Connects Claude to 9,500 cryptographically verified compliance nodes spanning EU AI Act, GDPR, HIPAA, DORA, NIST, MITRE ATT&CK, and 34 other regulatory frameworks. Nine tools let you search nodes by keyword, fetch dependency chains, cross-walk frameworks (like GDPR Article 17 to CCPA right-to-delete), pull jurisdiction-specific bundles, and run pre-flight compliance checks on natural language actions. Every node traces to primary legal sources with an average of seven citations and includes machine-executable workflows instead of summaries. Discovery tier is free over streamable HTTP with no API key. Reach for this when you need deterministic regulatory answers tied to actual legal instruments, not LLM inference.
10,000+ source-verified regulatory compliance nodes across 39 sovereign pillars. Built to reduce hallucination by grounding every node in primary legal sources.
Actively maintained. Last reviewed 2026-07-19 - 10,000+ nodes across 39 pillars, 25 MCP tools (server v1.6.0). Live counts always available via list_pillars() and GET https://bidda.com/mcp.
Bidda is a sovereign compliance intelligence registry. Every node traces to a primary legal source (avg 7 citations per node) and contains machine-executable deterministic logic, not summaries, not PDFs, not paraphrased commentary.
Pillars covered: EU AI Act · GDPR · NIST AI 600-1 · Basel III · HIPAA · DORA · FATF · SOC 2 · ISO 27001 · CCPA · PIPEDA · APRA CPS 234 · MiCA · POPIA · plus a MITRE layer across ATT&CK Enterprise/Mobile/ICS, D3FEND, ATLAS and CAPEC, and 150+ others across 39 compliance domains.

| Tool | Description |
|---|---|
list_pillars | List all 39 compliance pillars with live node counts |
search_nodes | Search by keyword across 10,000+ nodes; returns title, ID, pillar, and BLUF (plain-language obligation) |
get_node | Fetch a specific node by ID; returns summary plus link to machine-executable workflow |
get_dependency_chain | Walk the prerequisite chain for a node (1 to 4 hops). Plan a full compliance posture from one entry node. |
get_crosswalk | Cross-framework mapping dimensions for a node (e.g. GDPR Art 17 to CCPA right-to-delete to POPIA Sec 24) |
get_latest_changes | Regulatory change feed: most recently updated nodes, optional pillar filter |
get_jurisdiction_bundle | All nodes that apply in a specific jurisdiction (EU, US, UK, AU, SG, IN, CA, CN, ZA, JP, BR and others) |
get_mitre_mapping | MITRE technique ID to Bidda node plus mapped NIST/ISO/PCI/HIPAA/NIS2/DORA controls. Across 6 frameworks. |
check_action_compliance | Pre-flight runtime check. Describe an intended action in natural language; get ranked applicable regulations plus LOW/MODERATE/HIGH risk indicator. |
browse_topics | Browse the registry by cross-cutting compliance topic (e.g. data breach notification, AI transparency) across every pillar and jurisdiction |
api_key; a free trial counts)| Tool | Description |
|---|---|
compare_jurisdictions | Compare how jurisdictions address a topic side by side, including where their numeric thresholds differ (e.g. a breach-notification deadline of 72 hours versus 30 days). Does not rank which is stricter. |
create_attestation | Create a signed, time-stamped record of which rules a person or AI agent relied on for a decision, with a public verify URL |
point_in_time | Signed record of which committed version of a rule was authoritative at a past date, anchored to the public history chain |
watch_changes | Subscribe to email or webhook alerts when a watched rule or pillar's primary source changes |
open_run | Open a run ledger for a whole task or conversation (for example a support-bot chat). Returns a run_id. |
record_run_entry | Append one tamper-evident entry to an open run: the rules consulted, the decision, and the user input as text or a private hash |
seal_run | Seal a run into one signed run receipt covering every entry, with a public verify URL anyone can check against Bidda's public key |
get_run | Fetch a run and its entries; a sealed run is publicly readable and reports whether its signature is valid |
consult_node | Governed runs: fetch a full node and record a verified, hash-pinned entry in an open run in one call, so the sealed receipt proves exactly which version of the rule the agent read |
get_audit_pack | Export a sealed run as one auditor-ready evidence pack: the signed receipt, the entry chain, and an independent integrity self-check |
drift_check | Check whether a cached compliance snapshot is still current: pass node ids (optionally with version or content hash) and get fresh, drifted, or withdrawn per node |
create_control_attestation | Signed record mapping one of your internal controls to the Bidda obligations it addresses, with owner, framework, status, and a public verify URL. An audit trail, not a determination of compliance. |
gap_check | Walk the public dependency graph from the nodes you cover to surface prerequisite obligations you may be missing |
obligation_deltas | Obligation-level feed of which primary sources changed or were withdrawn since a date, filterable by pillar or node |
oscal_assessment_results | Export a sealed governed run as a NIST OSCAL assessment-results document for GRC tooling |
The discovery responses for every free tool are free. Full vault unlock (deterministic_workflow, actionable_schema, full primary_citations) costs $0.01 per node via Skyfire JWT or USDC on Base. The subscriber tools require an active Bidda subscription, which includes a free trial.

That is it: no install, no API key, no config file for the discovery tier. The full server-info manifest is available at GET https://bidda.com/mcp (open in a browser to inspect available tools).
This repo also ships a runnable local stdio MCP server (server.js) that declares the full 25-tool surface. The free discovery and intelligence tools run locally by calling the public Bidda REST API, with no API key. The subscriber and governance tools are declared with their full schemas and execute on the hosted endpoint at https://bidda.com/mcp with your Bidda key. Use it when you want the server running on your own machine or CI.
With Node (18+):
npm install
node server.js
With Docker:
docker build -t bidda-mcp .
docker run -i --rm bidda-mcp
Claude Desktop / Cursor config:
{
"mcpServers": {
"bidda": {
"command": "node",
"args": ["/absolute/path/to/bidda-mcp/server.js"]
}
}
}
The local server declares all 25 tools. Ten run locally with no API key: list_pillars, search_nodes, get_node, get_dependency_chain, get_crosswalk, get_mitre_mapping, get_jurisdiction_bundle, browse_topics, get_latest_changes, and check_action_compliance. compare_jurisdictions uses your Bidda key when the comparison is gated. The remaining subscriber and governance tools (attestations, the run ledger, change alerts, drift checks, and OSCAL export) require a Bidda subscription key and execute on the hosted endpoint at https://bidda.com/mcp; a free trial counts.

Nodes are produced by Bidda's internal deterministic pipeline: source parsers and verification scripts do the heavy lifting, AI assists only in a small, tightly-gated drafting step, and every node passes multiple independent verification gates before publication. The whole design exists to keep drift to a minimum.
Every node has:
/api/v1/registry-health.jsonNo inference without a regulatory anchor. No blog posts. No secondary commentary. No Wikipedia. Bidda is an information tool, not legal advice; review each rule and its primary source before relying on it.
Bidda has publicly attested to the CISA Secure by Design Pledge, the seven public goals the U.S. Cybersecurity and Infrastructure Security Agency asks software manufacturers to commit to. Additional Bidda and CISA mappings:
