Descope Agentic Identity Hub vs Stytch Connected Apps

Descope Agentic Identity Hub

Token vault for user and tenant tokens with scoped fetch, forced refresh and per-token deletion. No tool catalogue, so you write every provider call yourself.

Stytch Connected Apps

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.

Descope Agentic Identity Hub

1. Sign the agent in as its own OAuth client and let Policies scope it, instead of shipping a management key
2. Treat a 404 from the token endpoint as a missing connection and send the user to the connect URL
3. Back off for the full window on a 429, 60 seconds for most management endpoints
4. Ask for a tenant token, not a user token, for organisation-wide API keys
5. Budget monthly active tokens, since every token fetched and used counts once a month

Stytch Connected Apps

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