1,000+ APIs with OAuth, API key and client-credentials auth handled. Audit trail only on Enterprise, and logs kept 15 days on every plan.

OAuth 2.1 authorisation server with DCR, CIMD and PKCE out of the box. No outbound token vault, so it can't hold your users' third-party tokens.

Create one agent session per tenant from your backend and pass only the mcp_url and session_token to the agent
Tag connections with your own user and organisation IDs so sessions can select them
Listen for the refresh-failure webhook and send the user a reconnect link instead of retrying
Read the rate-limit headers on a 429 and wait for the reset before resuming
Run 0.71.6 or later when self-hosting, and keep the runner port off the network

Fetch {project-domain}/.well-known/oauth-authorization-server first and use the endpoints it returns, not hard-coded paths
Register with token_endpoint_auth_method none and PKCE S256 when the agent can't keep a secret
Expect a 401 with protected resource metadata from the MCP server, then register and authorise
Ask only for scopes the user's roles can grant, or the consent page will refuse them
Back off exponentially on a 429, since no Retry-After header is documented
