Create an Agent Knowledge MCP session
Issues a five-minute, read-only Streamable HTTP MCP capability for an active Agent in the verified Organization. Requires agents:read and knowledge:read. Use the returned token as Authorization: Bearer when calling the returned URL from an MCP client. It searches only the Agent’s current assigned documents; it cannot access business tools. Treat the token as a secret. Retrying issues another temporary capability; no persistent session is created.

}Authorizations
Organization-scoped Auth0 user access token issued to an approved first-party client or exchanged by a trusted OBO resource server.
Path Parameters
Opaque Arbol resource identifier; the endpoint and tenant-scoped lookup determine its resource type.
64^[a-z][a-z0-9]{1,15}_[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}$"agt_018f47a2-4f4d-7d61-9e2c-1d7b8e9a0c31"
Body
The body is of type object.
Response
OK
Five-minute read-only MCP bearer capability. Send token in the Authorization: Bearer header to url. Keep it secret; it grants only this active Agent's current document allowlist, never business tools. Mint a new session after expiry.
