This is the reference MCP server for the Open Primitive Protocol, a spec for wrapping data in verifiable envelopes with provenance chains and Ed25519 signatures. The 33 tools connect to 30 US federal data domains across agencies like FDA, EPA, and USGS. Every response includes freshness timestamps, confidence scores, citations, and cryptographic proofs. You'd reach for this when you need Claude to pull authoritative government data with full audit trails, whether that's drug adverse events from FAERS, EPA air quality readings, or USGS earthquake reports. The protocol itself is MIT licensed and designed for any data provider to implement, but this server gives you immediate access to federal datasets with Level 3 conformance.
