概要

What is Open Primitive Mcp?

The MCP server for the Open Primitive Protocol (OPP), providing 13 tools for Claude, Cursor, and MCP-compatible agents. OPP defines how data providers make their data agent-consumable, verifiable, and discoverable through provider manifests, response envelopes, and a standardized query interface.

How to use Open Primitive Mcp?

Run npx open-primitive-mcp to start the server, then query OPP providers using MCP-compatible clients. For example, fetch drug data with parameters like ?name=aspirin and receive a signed envelope containing citations and provenance.

Key features of Open Primitive Mcp

  • 13 tools for Claude, Cursor, and MCP-compatible agents
  • Every response carries domain, source, freshness, confidence, citation, and Ed25519 signature
  • Three conformance levels: Basic, Cited, and Verified
  • Reference implementation covering 16 US federal data domains across 11 agencies
  • SDKs for client consumption, provider implementation, and conformance validation

Use cases of Open Primitive Mcp

  • Agents retrieving FDA adverse event reports with verifiable provenance
  • Data providers wrapping existing APIs in the OPP envelope for agent consumption
  • Validating that a provider’s responses meet OPP conformance levels

よくある質問

1

How do I start the server?

Use `npx open-primitive-mcp` with Node.js installed.

2

What data does the reference implementation provide?

16 US federal data domains across 11 agencies, all Level 3 (Verified) compliant with cryptographic signatures.

3

How is data authenticity guaranteed?

Every response includes an Ed25519 signature with `proof.type: "DataIntegrityProof"`.

4

Can I use OPP for my own data?

Yes – create a `/.well-known/opp.json` manifest, wrap responses in the OPP envelope, and optionally sign with Ed25519.

5

What transport does the server use?

Standard HTTP GET endpoints with predictable query parameters.
