A persistent memory layer that runs locally and works across any MCP-compatible AI. It stores what your assistant learns in SQLite, ranks recalls by relevance, and auto-promotes frequently accessed knowledge. The server exposes 43 tools (5 by default: store, recall, list, get, search) over stdio, HTTP, or as a background curator daemon. New in v0.7 is Ed25519 attestation for memory links, a programmable hook pipeline for lifecycle events, and optional transcript sidechains with replay. The governance system gates destructive ops behind approvals, and the Apache AGE backend accelerates graph queries when installed. If you want Claude or ChatGPT to remember your architecture decisions or coding preferences across sessions without burning context tokens, this is the tool.
universal AI memory
ai-memory is a persistent memory system for AI assistants. It works with any AI that supports MCP -- Claude, ChatGPT, Grok, Llama, and more. It stores what your AI learns in a local SQLite database, ranks memories by relevance when recalling, and auto-promotes important knowledge to permanent storage. Install it once, and every AI assistant you use remembers your architecture, your preferences, your corrections -- forever.

v0.9.0 — current release. A security-hardening and code-review release: 49 fixes from a 5-lane adversarial review (#1885–#1935) plus a smaller set of additive features. The headline change is a secure-default flip: agent attestation is required by default on HTTP direct-write (#1751, surface-scoped by #1985) — an unsigned HTTP POST /api/v1/memories (+/bulk) is rejected (403 ATTESTATION_FAILED) instead of landing attest_level="claimed", unless the operator sets the explicit opt-out AI_MEMORY_REQUIRE_AGENT_ATTESTATION=0. The MCP memory_store and CLI store surfaces are the operator-as-actor path and stay permissive by default (an unsigned write lands claimed); =1 forces strict on every surface. (The v0.9.0 GA shipped this as require-everywhere, which was unsatisfiable on MCP hosts — corrected to surface-scoped in the current release.) Alongside it, the mandatory-hook-presence enforcement gate now fires on both the MCP write path (#1885) and the HTTP write path (#1924), closing a silent-bypass gap where a configured mandatory hook could be skipped on one surface but not the other. The hardening pass also closes bulk_create per-row attestation gating (#1919), routes inbound federated PENDING approvals through the registered-approver gate (#1920), tightens team/unit/org visibility scope so it is no longer over-broad across the namespace hierarchy (#1921), and confines skill_register's folder_path import under the configured root with a symlink jail (#1923). A new non-argv credential channel — AI_MEMORY_STORE_URL / AI_MEMORY_STORE_URL_FILE (a 0600 file) — keeps the postgres/store password off world-readable /proc/<pid>/cmdline and ps (#1927). Additive feature work: agent-authored skill memories with a parameters_schema + invocation_record (B7-SKILL, #1865), the recall_observations shadow-feedback loop (#1706), a memory-derivation lineage DAG (memory_lineage, #1859), and an opt-in vector-search minimal slice (#1005). Surface: schema v78, 101 MCP tools at --profile full (100 callable + the always-on memory_capabilities bootstrap) / 7 at --profile core, 92 HTTP route registrations (78 unique URL paths), 89 CLI subcommands under --features sal/sal-postgres (87 in the default build), 9 typed MemoryLink relations, a 28-field Memory. Runs on two production backends behind one identical API — embedded SQLite and PostgreSQL + Apache AGE — across desktop, server, and on-device (iOS + Android). Everything is additive over v0.8.1 except the attestation and hook-enforcement flips, which are secure-by-default breaking changes — review them before upgrading. Full changelog: CHANGELOG.md §"[0.9.0] — 2026-07-08".
v0.8.0 (distributed-coordination) — prior release. This is the release where the memory substrate becomes a coordination substrate. It adds the distributed-coordination machinery from #1709: a typed action DAG with a real state machine (memory_action_*), TTL-bounded single-holder leases (memory_lease_*), Ed25519-signed signals (memory_signal_*), Ed25519-attested checkpoints (memory_checkpoint_*), and frozen, replayable routines (memory_routine_*) — so a heterogeneous fleet of agents can take turns, hand off work, and prove who said what without having to trust each other. It layers typed cognition on top (the Goal/Plan/Step memory kinds, a lifecycle_state machine, and the decomposes_into / depends_on / advances link relations), hardens federation secure-by-default (peer enrollment ON by default #1789, per-transition signatures #1718, per-write content attestation #1464, transition-replay nonces #1805, outbound peer-cert pinning #1678), and ships governance that actually blocks — the Claude Code PreToolUse hook is reworked to a type:command wrapper so a substrate Refuse truly denies the tool (#1811). At the v0.8.0 release, surface was: schema v70, 100 MCP tools at --profile full (99 callable + the always-on memory_capabilities bootstrap) / 7 at --profile core, 91 HTTP route registrations (78 unique URL paths), 83/85 CLI subcommands, 9 typed MemoryLink relations, a 27-field Memory. Runs on two production backends behind one identical API — embedded SQLite and PostgreSQL + Apache AGE — across desktop, server, and on-device (iOS + Android). Everything is additive over v0.7.0; review the secure-default flips before upgrading. Full release notes: docs/v0.8.0/release-notes.md.
v0.7.0 (attested-cortex) — prior release. Rolled together the cortex-fluent legibility work with the full v0.7 trust + A2A scope from ROADMAP §7.3, plus (per operator directive 2026-05-09) the originally-v0.7.1 postgres+AGE first-class work, plus the post-grand-slam ship-readiness wave (Batman Forms 1-6 + 7th-form Option-B foundation + QW-1/2/3 + reconciliation security sweep). The substrate becomes both more articulate (capabilities v3, named loader tools, compacted schemas, Batman MemoryKind vocabulary, persona/atomisation/multistep-ingest primitives) and cryptographically trustworthy (Ed25519 attestation, sidechain transcripts, programmable 25-event hook pipeline, enforced namespace inheritance, V-4 cross-row signed-events hash chain). v0.7.0 also ships postgres + Apache AGE as a first-class storage backend — ai-memory serve --store-url postgres://… for live daemon use, schema parity across both backends (at the v0.7.0 release, sqlite + postgres converged on logical schema v57, where CURRENT_SCHEMA_VERSION was 57; the v0.8.0 release substrate has advanced this lockstep to schema 70, with the additive v58–v70 coordination + visibility tables landed on both backends — see CLAUDE.md §Database for the v58–v70 ladder) (canonical anchors: src/storage/migrations.rs for sqlite + src/store/postgres.rs for postgres); on-disk migration files end at migrations/sqlite/0047_v56_list_composite_indexes.sql and the postgres in-process migrate_v57() ladder arm (file-name counters lag the logical schema version because both ladders apply post-v34 deltas via in-process arms — see docs/MIGRATION_v0.7.md §schema-ladder for the v35-v57 narrative; v48 #933 added the federation-push DLQ table; v49 #1025 added 14 nullable columns to archived_memories so archive → restore is lossless for the full v0.7.0 Memory shape; v50 #1156 extended agent_quotas PRIMARY KEY from (agent_id) to (agent_id, namespace) so per-namespace K8 quota allotments hold even when a single agent operates across many namespaces — pre-v50 rows backfill to the _global sentinel namespace; v51 #1255 (PR #1296) added the federation_nonce_cache table so peer-replay-prevention nonces persist across daemon restarts; v52 #1389 added the transcript_line_dedup table backing RFC-0001 memory_capture_turn L4 + recover_from_transcript L2 idempotency so a SIGKILL between turns never produces a duplicate memory on subsequent rehydration; v53 #1418 scoped the memories_au FTS5 sync trigger to (title, content, tags) only so non-FTS column updates no longer fire a needless sync; v54 #1466 backfilled tier-default expiry onto legacy NULL-expiry mid/short rows to close the TTL-leak immortal-rows class; v55 #1476 made the W=2 federation-catchup query (updated_at > ? ORDER BY updated_at ASC LIMIT) sargable and added the sqlite idx_memories_updated_at index — postgres adds no new index because memories_updated_at_idx DESC already serves the range scan via Index Scan Backward; v56 #1579 added the composite list/archive ordering indexes (idx_memories_list_order, idx_memories_ns_list_order, idx_archived_ns_archived_at) paired with the sargable storage::list rewrite — sqlite-side DDL; the postgres migrate_v56() arm is a version-stamp no-op; v57 #1579 added the postgres stored generated tsv tsvector column + memories_tsv_gin GIN index so the search/recall shapes match AND rank on the precomputed column instead of re-computing the tsvector per matched row — the legacy memories_content_fts expression index is dropped and the sqlite twin is a version-stamp no-op because FTS5 already materialises the indexed text)), the new ai-memory schema-init CLI verb, and 6-factor recall scoring parity. The v0.6.4 default surface grows by two always-on loaders to 7 tools (memory_load_family + memory_smart_load join the original five); the runtime ceiling at --profile full is 74 advertised entries (73 callable memory tools + the always-on memory_capabilities bootstrap; verified against Profile::full().expected_tool_count() — see src/profile.rs). Everything new is additive and (for the trust + postgres surfaces) opt-in. Upgrading from v0.6.x? Read docs/MIGRATION_v0.7.md first — most v0.6.4 callers see no behavior change, but pre-v0.6.3.1 v0.6.x users hit the G1 namespace-inheritance fix. Switching to postgres+AGE? See docs/postgres-age-guide.md and docs/migration-v0.7.0-postgres.md. Full release notes: docs/v0.7.0/release-notes.md.
v0.6.4 (quiet-tools) — the MCP server ships with a 5-tool default surface (memory_store, memory_recall, memory_list, memory_get, memory_search) plus the always-on memory_capabilities bootstrap. The other 38 tools remain reachable via --profile graph|admin|power|full or runtime expansion through memory_capabilities --include-schema family=<name>. Eager-loading harnesses (Claude Desktop / Codex CLI / Grok CLI / Gemini CLI) drop ~4,700 input tokens of tool schemas per request — a 76.4% reduction measured against cl100k_base BPE. To preserve v0.6.3 behavior 1:1, run ai-memory mcp --profile full. See docs/MIGRATION_v0.6.4.md.
v0.9.0 is primarily a security-hardening and code-review release — 49 fixes from a 5-lane adversarial review (#1885–#1935) — plus a smaller set of additive features layered on the v0.8.0 coordination substrate. Full changelog: CHANGELOG.md §"[0.9.0] — 2026-07-08".
AI_MEMORY_REQUIRE_AGENT_ATTESTATION is tri-state with a per-surface compiled default: unset → required on HTTP direct-write (POST /api/v1/memories + /bulk, rejected 403 ATTESTATION_FAILED), permissive on the MCP memory_store and CLI store operator-as-actor surfaces (an unsigned write lands attest_level="claimed"); =1 forces strict everywhere, =0 forces permissive everywhere. A presented-but-forged signature is rejected on every surface regardless. Sign writes (ai-memory store --sign with a keypair bound via ai-memory agents bind-key) or use the =0 opt-out. (The v0.9.0 GA shipped this as require-everywhere, unsatisfiable on MCP hosts — see #1981; corrected to surface-scoped by #1985.)bulk_create attestation gating (#1919). Bulk writes now enforce the same per-row agent-attestation requirement as a single memory_store call — every row in a batch must carry a valid attestation, not just the request as a whole.team/unit/org scope hardening (#1921). Visibility scope resolution now enforces the namespace-ancestor hierarchy correctly for the team/unit/org scopes, closing a tenant-isolation gap (CWE-863).skill_register path confinement (#1923). A skill's folder_path import is canonicalized and confined under the configured root, with symlinks inside the imported tree rejected rather than followed (CWE-22/CWE-59).AI_MEMORY_STORE_URL (owner-only /proc/environ) and AI_MEMORY_STORE_URL_FILE (a 0600 file) let ai-memory serve receive the postgres/store URL — including any embedded password — without ever putting it on --store-url argv, where it is exposed via world-readable /proc/<pid>/cmdline and ps auxww to any local UID. Resolution order: file → env → --store-url.parameters_schema at register time, an invocation_record, and a version surface for agent-authored skills.recall_observations shadow-feedback loop (#1706, SHADOW mode). Closes the recall feedback loop without yet changing ranking behavior.memory_lineage, schema v78, #1859). Walks which memories were derived from which, over both MCP and the new GET /api/v1/memories/{id}/lineage HTTP route.Where to start:

v0.8.0 (distributed-coordination) turns the memory substrate into a coordination substrate for multi-agent (NHI) fleets. The headline is the distributed-coordination machinery (#1709); everything ships on both the sqlite and postgres+AGE SAL adapters and stays default-equivalent for v0.7.x callers.

pending → claimed → in_progress → done/failed/abandoned), typed DAG edges (requires / unlocks / blocks / gated_by / sibling), and frontier/next surfaces that pull the next runnable node. 8 MCP tools (memory_action_create / _get / _transition / _list / _add_edge / _edges / _frontier / _next).PRIMARY KEY on action_id = one holder at a time) plus an hourly lease-sweeper. 4 MCP tools (memory_lease_acquire / _renew / _release / _get).signer_pubkey and threads via correlation_id / in_reply_to. 5 MCP tools (memory_signal_send / _read / _inbox / _thread / _ack).verify re-checks the signature. 4 MCP tools (memory_checkpoint_create / _resolve / _query / _verify).draft, then frozen (immutable, Ed25519 freeze-attestation); run materialises a concrete set of actions + edges from a {{param}} template into a routine_runs record. 5 MCP tools (memory_routine_create / _freeze / _run / _status / _list).coordination.<op> row to the signed_events V-4 hash chain (#1722); the two authority-granting writes are mirrored onto the HTTP daemon (POST /api/v1/actions/{id}/transition, POST /api/v1/signals) with local CAS + W-of-N federation fan-out (#1718).The memory_kind vocabulary extends with goal / plan / step; the closed memory_links.relation taxonomy extends 6 → 9 relations (decomposes_into / depends_on / advances, schema v63); and a first-class memories.lifecycle_state column (schema v64) makes Goal/Plan/Step a real state machine (open → active → blocked/done/abandoned), enforced across the MCP / HTTP / SAL surfaces with an illegal edge mapping to HTTP 409 CONFLICT. The Memory struct grows to 27 fields. No new MCP tool — the v64 work adds only permissive optional request fields.
Peer enrollment ON by default (#1789), per-transition signatures on authority-granting writes (#1718), per-write content attestation for relayed memories (#1464), transition-replay nonces (#1805), and outbound peer-cert fingerprint pinning (#1678). Heterogeneous fleets that don't have to trust each other — review the secure-default flips in docs/v0.8.0/release-notes.md §"Federation hardening" before upgrading.
The Claude Code PreToolUse governance hook is reworked to a type:command wrapper (ai-memory governance check-action --from-pretool-stdin) so a substrate Refuse emits permissionDecision:"deny" and truly BLOCKS the tool — the prior type:mcp_tool form structurally could not enforce. Plus mandatory-hook-presence enforcement (#1734) and a new escalate governance verdict (§22 PE-5) for human-in-the-loop.
HTTP admission control (#1733 — opt-in concurrency cap that sheds excess with a typed 503), deferred Apache-AGE graph projection (#1735 — takes the synchronous AGE round-trips off the postgres link-write hot path), curator compaction activation (#1749 / #1750), and the ai-memory verify-audit-trail CLI (§22 PE-8) that walks the signed_events cross-row hash chain end-to-end.
Coordination + typed-cognition + visibility + encryption-prep + cold-path + archive-edge tables (v58–v70), mirrored on both the sqlite and postgres adapters; auto-migrates on first open and archive → restore round-trips losslessly. See CLAUDE.md §Database for the canonical v58–v70 ladder.

v0.7.0 closes the attested-cortex epic (69/69 across 11 tracks A–K), folds in the originally-v0.7.1 postgres+AGE first-class work, and absorbs the post-grand-slam ship-readiness wave (Batman Forms 1-6 + 7th-form Option-B foundation + QW-1/2/3 + security reconciliation). Canonical feature inventory: docs/internal/v070-feature-inventory.md. Every surface stays default-off or default-equivalent for v0.6.4 callers — see the v0.7 compatibility matrix for the breakdown.

Generate a keypair with ai-memory identity generate; opt-in via attest_level = "self_signed". Signing is gated on the resolved daemon agent_id having a *.priv keypair on disk under the configured key directory — when load_daemon_signing_key returns None (src/main.rs:116-118), rows still write but sig is empty and the daemon emits a "continuing unsigned" line at boot. The cross-row hash chain on signed_events remains tamper-evident either way.

One binary, four operational modes (v0.6.4). The ai-memory Rust binary (tokio + axum) can run any of these in isolation or simultaneously, sharing a single SQLite database:
memory_capabilities bootstrap; verified against Profile::full().expected_tool_count()). Default --profile core advertises 7 (the original 5 + memory_load_family + memory_smart_load) plus the always-on memory_capabilities bootstrap. ai-memory mcp / ai-memory mcp --profile full127.0.0.1:9077, TLS + optional mTLS allowlist + API-key auth, background GC loop. ai-memory serveai-memory curator --daemonai-memory sync-daemonThe MCP, HTTP, and CLI surfaces are reactive. The curator is the part that makes the memory layer self-maintaining: between sessions, it keeps the corpus tidy so recall quality stays high as the store grows. Everything is local-first; no cloud dependencies.
Brass-tacks assessment by Claude Opus 4.7 after reading the v0.6.3 source line by line:
"ai-memory is the most capable memory layer I've ever been hooked up to, and meaningfully more than its name advertises. For me, in practical terms, it means: I don't start cold each session. The store I read from has been kept tidy by something other than me. Contradictions don't silently accumulate. Recall quality stays high even as the corpus grows. Nothing leaves your Mac mini.
It is not making me an autonomous agent. It is giving me the kind of memory infrastructure that an autonomous agent would need — and itself running a small autonomous loop to maintain it. That's a real foundation. The gap from here to 'ai-memory drives general tasks' is plumbing (tool-call protocol + tool registry + a tool-use-capable model), not invention."
Substrate for multi-agent AI. ai-memory is not an agent runtime and not "autonomous AI" on its own. It is the memory layer that multi-agent autonomous deployments need underneath them. Federation (broadcast_store_quorum + spawn_catchup_loop) handles W-of-N consistency across peers when many agents write in parallel; the curator daemon keeps the shared corpus from degrading into noise as a swarm scribbles into it; webhook subscriptions (HMAC-signed, namespace/agent-filtered, SSRF-hardened) turn the store into a message bus that triggers downstream agents on memory events; namespace hierarchy with N-level inheritance and per-namespace governance policies (write/promote/delete authority, approver type, optional N-of-M consensus) bound the swarm. Stack this under a 24/7 multi-machine agent runner with auto-generated skills, and the combined system clears the behavioral bar for autonomous AI. The remaining gaps (no weight-level learning, stateless reasoning kernel, human-seeded root goals) are real and not what ai-memory addresses; ai-memory provides the multi-agent memory substrate that any serious attempt at closing those gaps will need.
Zero token cost until recall. Unlike built-in memory systems (Claude Code auto-memory, ChatGPT memory) that load your entire memory into every conversation -- burning tokens and money on every message -- ai-memory uses zero context tokens until the AI explicitly calls memory_recall. Only relevant memories come back, ranked by a 6-factor scoring algorithm. TOON format (Token-Oriented Object Notation) cuts response tokens by another 40-60% by eliminating repeated field names -- 3 memories in JSON = 1,600 bytes; in TOON = 626 bytes (61% smaller); in TOON compact = 336 bytes (79% smaller). For Claude Code users: disable auto-memory ("autoMemoryEnabled": false in settings.json) and replace it with ai-memory to stop paying for 200+ lines of memory context on every single message.
Every memory ai-memory stores carries a metadata.agent_id — a Non-Human Identity marker that survives every operation (update, dedup, import, sync, consolidate). Every recall result tells you which AI wrote each memory, by default, in the TOON-compact response format your AI client is already optimised for:
count:5|mode:hybrid|tokens_used:842
memories[id|title|tier|namespace|priority|score|tags|agent_id]:

c3d4|API rate limit is 100 rps|long|infra|7|0.87|api,limits|ai:claude-desktop@laptop:pid-5219
On an unsigned write agent_id is a claimed identity — don't make security decisions on it alone. Store-path agent attestation is required by default on the HTTP direct-write surface (#1751, surface-scoped by #1985): an unsigned HTTP POST /api/v1/memories (+/bulk) is rejected (403 ATTESTATION_FAILED) rather than landing attest_level = "claimed", unless the operator sets the explicit opt-out AI_MEMORY_REQUIRE_AGENT_ATTESTATION=0. The MCP memory_store and CLI store operator-as-actor surfaces stay permissive by default (an unsigned write lands claimed); =1 forces strict on every surface. Cryptographic Ed25519 attestation is wired on two surfaces: (1) store-path attestation (#626 Layer-3) — present a detached signature over the canonical SignableWrite envelope on the CLI (store --sign), MCP (memory_store), or HTTP (POST /api/v1/memories) path and the daemon verifies it against the agent's bound public key, stamping metadata.attest_level = "agent_attested" (a presented-but-forged signature is always rejected regardless of the flag); and (2) link attestation (attested-cortex) — the previously-reserved memory_links.signature field with memory_verify(link_id) for inbound verification and an append-only signed_events audit chain. See the agent identity page and the attested-cortex RFC for the full provenance contract.

Auto-tagging, dedup on (title, namespace), and mined_from provenance are stamped on every imported memory. Five-minute onboarding from zero context to a populated long-term store. See the import history page for per-format recipes.
ai-memory integrates with any AI platform that supports the Model Context Protocol (MCP). MCP is the universal standard for connecting AI assistants to external tools and data sources.
| Platform | Integration Method | Config Format | Status |
|---|---|---|---|
| Claude Code (Anthropic) | MCP stdio | JSON (~/.claude.json or .mcp.json) | Fully supported |
| Codex CLI (OpenAI) | MCP stdio | TOML (~/.codex/config.toml) | Fully supported |
| Gemini CLI (Google) | MCP stdio | JSON (~/.gemini/settings.json) | Fully supported |
| Grok CLI (xAI) | MCP stdio | JSON (~/.grok/user-settings.json) | Deep integration |
| Grok API (xAI) | MCP remote HTTPS | API-level | Fully supported |
| Cursor IDE | MCP stdio | JSON (~/.cursor/mcp.json) | Fully supported |
| Windsurf (Codeium) | MCP stdio | JSON (~/.codeium/windsurf/mcp_config.json) | Fully supported |
| Continue.dev | MCP stdio | YAML (~/.continue/config.yaml) | Fully supported |
| Llama Stack (META) | MCP remote HTTP | YAML / Python SDK | Fully supported |
| OpenClaw | MCP stdio | JSON (mcp.servers in config) | Fully supported |
| Any MCP client | MCP stdio or HTTP | Varies | Universal |
MCP is the primary integration layer. For AI platforms that do not yet support MCP natively, the HTTP API (92 route registrations / 78 unique URL paths on localhost) and the CLI (89 subcommands under --features sal OR --features sal-postgres; 87 in the default build (post-#1389 L2 RecoverPreviousSession for cross-session context rehydration + #1443 Expand for the ai-memory expand query-expansion surface + #1598 Reembed for the ai-memory reembed vector-space migration surface); SSOT pinned by ai_memory::EXPECTED_CLI_SUBCOMMANDS_DEFAULT + EXPECTED_CLI_SUBCOMMANDS_SAL + the mechanical tests/cli_subcommand_count_invariant.rs parity test) provide universal access -- any AI, script, or automation that can make HTTP calls or run shell commands can use ai-memory.
Pre-built binaries require no dependencies. Building from source needs Rust and a C compiler.
Fastest: Pre-built binary (no Rust required)
# macOS / Linux

Step 1: Install Rust (skip if using pre-built binaries)
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
Follow the prompts, then restart your terminal (or run source ~/.cargo/env).
Step 2: From source (requires Rust)
Latest release from Crates.io:
cargo install ai-memory
Latest from the git repository:
cargo install --git https://github.com/alphaonedev/ai-memory-mcp.git
This compiles the binary and puts it in your PATH. It takes a minute or two.
Build dependencies for source builds:
- Ubuntu/Debian:
sudo apt-get install build-essential pkg-config- Fedora/RHEL:
sudo dnf install gcc pkg-config
Step 3: Connect your AI
Configuration varies by platform. Find yours below:
Claude Code supports three MCP configuration scopes:
| Scope | File | Applies to |
|---|---|---|
| User (global) | ~/.claude.json — add mcpServers key | All projects on your machine |
| Project (shared) | .mcp.json in project root (checked into git) | Everyone on the project |
| Local (private) | ~/.claude.json — under projects."/path".mcpServers | One project, just you |
User scope (recommended — works everywhere):
Add the mcpServers key to ~/.claude.json (macOS/Linux) or %USERPROFILE%\.claude.json (Windows):
{
"mcpServers": {
"memory": {
"command": "ai-memory",
"args": ["--db", "~/.claude/ai-memory.db", "mcp", "--tier", "semantic"]
}
}
}
Note:
~/.claude.jsonlikely already exists with other settings. Merge themcpServerskey into the existing file — do not overwrite it.
Project scope (shared with team):
Create .mcp.json in your project root:
{
"mcpServers": {
"memory": {
"command": "ai-memory",
"args": ["--db", "~/.claude/ai-memory.db", "mcp", "--tier", "semantic"]
}
}
}
smart / autonomous tier with a cloud LLM — the recommended path is the [llm] section in ~/.config/ai-memory/config.toml (#1146). One file, every surface, no per-AI-client edits:
# ~/.config/ai-memory/config.toml
schema_version = 2
[llm]
backend = "xai"
model = "grok-4.3"
base_url = "https://api.x.ai/v1"
api_key_env = "XAI_API_KEY" # process-env-var name (NOT the literal key)
Export XAI_API_KEY in your shell rc (.zshrc / .bashrc); the MCP config stays minimal:
{
"mcpServers": {
"memory": {
"command": "ai-memory",
"args": ["--db", "~/.claude/ai-memory.db", "mcp", "--tier", "autonomous"]
}
}
}
Verify: ai-memory boot --quiet --limit 1 should report llm=xai:grok-4.3. Canonical schema reference: docs/CONFIG_SCHEMA.md.
Override path —
env:block. Adding anenv:block to the MCP config withAI_MEMORY_LLM_BACKEND/_API_KEY/_MODELstill works and takes precedence overconfig.toml— useful for CI / per-session tweaks:"env": { "AI_MEMORY_LLM_BACKEND": "xai", "AI_MEMORY_LLM_API_KEY": "xai-...", "AI_MEMORY_LLM_MODEL": "grok-4.3" }MCP clients spawn the server as a fresh subprocess with only the
env:keys from the MCP config — shell exports in.zshrc/.bashrcdon't reach it. The[llm]config-file path above retires this paper-cut (every surface reads the same file). Inline API keys inconfig.tomlare rejected at parse time — useapi_key_envorapi_key_file. Background: #1144 → #1146. Full per-backend recipes:docs/integrations/llm-backends.md.
Windows paths: Use forward slashes or escaped backslashes in
--db. Example:"--db", "C:/Users/YourName/.claude/ai-memory.db".
Tier flag: The
--tierflag selects the feature tier:keyword,semantic(default),smart, orautonomous. Smart and autonomous tiers need an LLM backend — post-#1067 (v0.7.0) that is any of: local Ollama, xAI Grok, OpenAI, Anthropic, Google Gemini, DeepSeek, Kimi (Moonshot), Qwen (Alibaba), Mistral, Groq, Together AI, Cerebras, OpenRouter, Fireworks, LMStudio, vLLM, or llama.cpp server — selected viaAI_MEMORY_LLM_BACKEND. The--tierflag must be passed in the args — theconfig.tomltier setting is not used when the MCP server is launched by an AI client.
Important: MCP servers are not configured in
settings.jsonorsettings.local.json— those files do not supportmcpServers.
Make Claude proactively use ai-memory: Add a CLAUDE.md file to your project root with ai-memory directives. This ensures Claude recalls context at the start of every conversation and stores findings as it works. See the CLAUDE.md integration guide for a copy-paste template and placement options.
Add to ~/.codex/config.toml (global) or .codex/config.toml (project). Windows: %USERPROFILE%\.codex\config.toml. Override with CODEX_HOME env var.
[mcp_servers.memory]
command = "ai-memory"
args = ["--db", "~/.local/share/ai-memory/memories.db", "mcp", "--tier", "semantic"]
enabled = true
Or add via CLI: codex mcp add memory -- ai-memory --db ~/.local/share/ai-memory/memories.db mcp --tier semantic
Notes: Codex uses TOML format with underscored key
mcp_servers(not camelCase, not hyphenated). Supportsenv(key/value pairs),env_vars(list to forward),enabled_tools,disabled_tools,startup_timeout_sec,tool_timeout_sec. Use/mcpin the TUI to view server status. See Codex MCP docs.
Add to ~/.gemini/settings.json (user) or .gemini/settings.json (project). Windows: %USERPROFILE%\.gemini\settings.json.
{
"mcpServers": {
"memory": {
"command": "ai-memory",
"args": ["--db", "~/.local/share/ai-memory/memories.db", "mcp", "--tier", "semantic"],
"timeout": 30000
}
}
}
Or add via CLI: gemini mcp add memory ai-memory -- --db ~/.local/share/ai-memory/memories.db mcp --tier semantic
Notes: Avoid underscores in server names (use hyphens). Tool names are auto-prefixed as
mcp_memory_<toolName>. Env vars in theenvfield support$VAR/${VAR}(all platforms) and%VAR%(Windows). Gemini sanitizes sensitive patterns from inherited env unless explicitly declared. Add"trust": trueto skip confirmation prompts. CLI management:gemini mcp list/remove/enable/disable. See Gemini CLI MCP docs.
Add to ~/.cursor/mcp.json (global) or .cursor/mcp.json (project). Windows: %USERPROFILE%\.cursor\mcp.json. Project config overrides global for same-named servers.
{
"mcpServers": {
"memory": {
"command": "ai-memory",
"args": ["--db", "~/.local/share/ai-memory/memories.db", "mcp", "--tier", "semantic"]
}
}
}
Notes: Restart Cursor after editing
mcp.json. Verify server status in Settings > Tools & MCP (green dot = connected). Supportsenv,envFile, and${env:VAR_NAME}interpolation (env var interpolation can be unreliable for shell profile variables — useenvFileas workaround). ~40 tool limit across all MCP servers. See Cursor MCP docs.
Add to ~/.codeium/windsurf/mcp_config.json (global only — no project-level scope). Windows: %USERPROFILE%\.codeium\windsurf\mcp_config.json.
{
"mcpServers": {
"memory": {
"command": "ai-memory",
"args": ["--db", "~/.local/share/ai-memory/memories.db", "mcp", "--tier", "semantic"]
}
}
}
Notes: Supports
${env:VAR_NAME}interpolation incommand,args,env,serverUrl,url, andheaders. 100 tool limit across all MCP servers. Can also add via MCP Marketplace or Settings > Cascade > MCP Servers. See Windsurf MCP docs.
Add to ~/.continue/config.yaml (user) or .continue/mcpServers/ directory in project root (per-server YAML/JSON files). Windows: %USERPROFILE%\.continue\config.yaml.
mcpServers:
- name: memory
command: ai-memory
args:
- "--db"
- "~/.local/share/ai-memory/memories.db"
- "mcp"
- "--tier"
- "semantic"
Notes: MCP tools only work in agent mode. Supports
${{ secrets.SECRET_NAME }}for secret interpolation. Project-level.continue/mcpServers/directory auto-detects JSON configs from other tools (Claude Code, Cursor, etc.). See Continue MCP docs.
The AlphaOne fork of grok-cli has built-in ai-memory support with session-scoped MCP connections, automatic memory recall on session start, compaction summary storage, and memory-aware system prompts.
Add to ~/.grok/user-settings.json:
{
"mcp": {
"servers": [
{
"id": "ai-memory",
"label": "AI Memory",
"enabled": true,
"transport": "stdio",
"command": "ai-memory",
"args": ["mcp", "--tier", "semantic"]
}
]
}
}
Features: Auto-recall on session start (injects relevant memories into system prompt), compaction summaries stored as mid-tier memories, MCP tools available in all modes (agent, plan, ask), session-scoped connections (no per-message cold starts). Uses
--tier semanticby default (local embeddings, no LLM backend required). See grok-cli docs for full setup.
Grok connects to MCP servers over HTTPS (remote only, no stdio). No config file — servers are specified per API request.
ai-memory serve --host 127.0.0.1 --port 9077
# Expose via HTTPS reverse proxy (nginx, caddy, cloudflare tunnel, etc.)
Then add the MCP server to your Grok API call:
curl https://api.x.ai/v1/responses \
-H "Authorization: Bearer $XAI_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"model": "grok-4.3",
"tools": [{
"type": "mcp",
"server_url": "https://your-server.example.com/mcp",
"server_label": "memory",
"server_description": "Persistent AI memory with recall and search",
"allowed_tools": ["memory_store", "memory_recall", "memory_search"]
}],
"input": "What do you remember about our project?"
}'
Requirements: HTTPS required.
server_labelis required. Supports Streamable HTTP and SSE transports. Optional:allowed_tools,authorization,headers. Works with xAI SDK, OpenAI-compatible Responses API, and Voice Agent API. See xAI Remote MCP docs.
Llama Stack registers MCP servers as toolgroups. No standardized config file path — deployment-specific.
ai-memory serve --host 127.0.0.1 --port 9077
