MCP

MCP proxy (no streams)

GET/mcp/proxy/:uid

Answers 405: the proxy answers each request with one response and relays no server-initiated streams.

#Authentication

Agent key

An agent-scoped key (ask_...) bound to exactly one agent, or an OAuth access token (aat_...) issued to an MCP client for that agent, sent as Authorization: Bearer. An agent key may ask, poll and settle. It can never approve, widen a mandate or lift a freeze.

#Path parameters
