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.
