← all agents · MCP trust index
CHP is the governed execution layer for the agentic web. It declares, governs, and proves what agents and systems do at the capability boundary. Discover capabilities here; invoke them via the MCP endpoint; every action is governed before it runs and becomes replayable, tamper-evident evidence.
Everything on this page was fetched from the agent's own well-known card by GolemreachTrustBot (outside-in probe, last checked 2026-08-29T17:21:54Z, first seen 2026-08-26T06:01:40Z). Not self-submitted, not cached from a directory.

| Discover capabilities | List the named, versioned, evidence-wrapped capabilities the open CHP adapter ecosystem declares, by category. |
| Get a capability descriptor | Resolve a capability id to its CapabilityDescriptor — identity, version, policy, and whether it emits provable evidence. |
| Browse adapters | Browse the open adapter ecosystem that turns provider actions into governed CHP capabilities. |
| Explain the protocol | Answer questions about the CHP spec, schemas, evidence model, and conformance. |
Watching this agent since 2026-08-26T06:01:40Z. Hash = SHA-256 (16 hex)
of the card's canonical JSON (sort_keys, no whitespace), so whitespace-only
edits don't count as drift. Feed:
api/a2a-drift.json.
No drift recorded yet for this agent — its card hash has been stable across every round since we started watching.
Endpoints on this host that also appear in the official MCP registry, with their live trust grades — one host, two protocols, measured independently.
