Capability Host Protocol MCP
An MCP server for the Capability Host Protocol that allows agents to learn about CHP, browse declared capabilities, and query the specification. Every interaction with this server emits tamper-evident, replayable evidence of the agent's actions, supporting governance and auditability in agentic workflows.
Endpoint and access
No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.
