Descope Agentic Identity Hub vs Nango

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.

Nango

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.

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

Nango

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