Seojeom Mcp

Seojeom MCP Server

Canonical repo location: packages/seojeom-mcp

During the Godot-only decommission transition, apps/desktop/mcp-server may already be absent. New work should treat this package path as the source of truth. If a deprecated local lane still needs the old path to exist, recreate the minimal metadata-wrapper with pnpm apply:legacy-compat-wrapper.

Local-first MCP server for Claude and Codex.

seojeom-mcp binds to the project currently opened by the Seojeom desktop app or Godot launcher through a shared registry directory, then serves that project's local wiki and graph data over stdio.

Quickstart

Claude Code

claude mcp add -s local \
  -e SEOJEOM_SHARED_REGISTRY_DIR=/mnt/c/Users/<you>/.seojeom/registry \
  seojeom -- npm exec --yes --package=seojeom-mcp seojeom-mcp -- \
  --router \
  --host-kind auto \
  --approval-mode prompt

Claude Desktop

Add this to claude_desktop_config.json and restart Claude Desktop:

{
  "mcpServers": {
    "seojeom": {
      "command": "npm",
      "env": {
        "SEOJEOM_SHARED_REGISTRY_DIR": "<shared-registry-dir>"
      },
      "args": [
        "exec",
        "--yes",
        "--package=seojeom-mcp",
        "seojeom-mcp",
        "--",
        "--router",
        "--host-kind", "auto",
        "--approval-mode", "prompt"
      ]
    }
  }
}

Print the exact onboarding command first

npm exec --yes --package=seojeom-mcp seojeom-mcp -- --print-claude-onboarding

What it provides

• project binding to the currently active desktop/Godot project
• local wiki read/search/write tools
• local graph read/search/query tools
• core graph mutation/proposal tools for local authoring tasks
• approval-gated mutating operations

The exact tool surface is discovered at runtime through MCP tools/list.

Runtime contract

• primary transport: stdio
• primary install path: npm exec --yes --package=seojeom-mcp seojeom-mcp --
• recommended mode: shared-registry router mode
• expected runtime: Node >=20.20.0
• public npm package shape: standalone stdio entrypoint only

Source build contract

Running pnpm build in this package is a dual-output build:

• dist/index.js and the rest of dist/** stay available as the local source/runtime HTTP sidecar surface used by Godot and other repo-local lanes
• .public-package/dist/standalone.js is the staged npm publish surface

After a successful build, you can verify both lanes with:

pnpm smoke:build-layout

Godot-side source verification can also run the local HTTP sidecar smoke directly from the canonical package root:

pnpm smoke:sidecar-health

Surface tiers

seojeom-mcp is not one uniform surface. Treat these as separate contracts:

1. npm public package

• audience: external Claude/Codex users installing from npm
• transport: stdio
• mode: shared-registry router
• published shape: LICENSE, README.md, bin/seojeom-mcp, dist/standalone.js, package.json
• capability promise: public tools only
• non-goals: internal prompts, internal resources, full authoring harness, desktop UI shell

This is the only contract guaranteed by the published npm package.

2. local full runtime

• audience: local maintainers running from source
• transport: stdio plus local sidecar HTTP runtime paths
• profile: full authoring surface
• includes: prompts, resources, specialized graph/wiki authoring flows, internal playbooks

This source-tree runtime is intentionally larger than the public package.

3. desktop-coupled runtime

• audience: local desktop/Godot-integrated operation
• product default: app-bundled sidecar runtime
• depends on: shared registry writer, approval queue UI, review shell, sidecar health surface
• examples: approval review pane, desktop approval alerts, graph IPC bearer-token flows
• debug override: sidecar entry override is reserved for debug-only startup paths

These desktop-coupled capabilities are not part of the standalone npm guarantee.

Registry

• MCP Registry identifier target: io.github.seojeom/seojeom-mcp
• planned publish mode: GitHub Actions Trusted Publishing + npm publish --provenance

Notes

• This package is still a preview release and the tool surface may evolve between versions.
• Router mode is the recommended public path. Direct per-project standalone flags remain as a compatibility fallback.
• The public package defaults to a core authoring tool surface. Prompts, resources, and more specialized orchestration surfaces are reserved for non-public/internal profiles.
• Public package documentation intentionally stays focused on installation and end-user usage. Internal release automation and repository-specific operator workflows are not part of the package contract.
