Bidda Sovereign Intelligence MCP Server

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.

What is Bidda?

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.

MCP Endpoint

POST https://bidda.com/mcp
GET  https://bidda.com/mcp   (server info, open this in a browser to inspect)

Transport: Streamable HTTP (MCP 2025-03-26). No API key required for the discovery tier.

Tools (25)

Free discovery and intelligence (no key required)

Subscriber tools (pass your Bidda key as api_key; a free trial counts)

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.

Quick Start: Claude.ai / Claude Desktop / Cursor / any MCP HTTP client

Point your MCP client at:

https://bidda.com/mcp

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).

Run it locally (Node or Docker)

This repo also ships a small local stdio MCP server (server.js) that implements the free discovery and intelligence tools by calling the public Bidda REST API - no API key required. 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 exposes seven tools: list_pillars, search_nodes, get_node, get_dependency_chain, get_latest_changes, browse_topics, and check_action_compliance. The subscriber, vault, and attestation tools are available only on the hosted endpoint at https://bidda.com/mcp.

How Bidda reduces hallucination

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:

• Primary legal citations: real instruments, real URLs, real section numbers (avg 7 per node)

• Deterministic workflow: machine-executable steps, not prose summaries

• Integrity hash: a cryptographic fingerprint of the node content

• Source integrity watcher: regular TLS and content fingerprint checks against live regulator URLs, results published at /api/v1/registry-health.json

• Verbatim mandate on amendments: every regulatory amendment is quote-justified against the source text before it can change a node

No 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.

CISA Secure by Design

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:

• CISA CPG crosswalk: bidirectional mapping between Bidda compliance nodes and CISA's Cybersecurity Performance Goals: bidda.com/cisa/cpg-crosswalk

• CISA Free Tools catalogue: no-cost capabilities Bidda offers federal, SLTT and critical-infrastructure defenders: bidda.com/cisa/free

Live integrity-check results: source URL liveness, verification coverage percentage, regulatory change detection categories, with a public timestamp on the last sweep.
