Verdicts

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.

Keycard

Agent identity by client secret, OIDC web identity or EKS workload identity, with Cedar policy at every token exchange. Early Access with sign-up by request, and no terms of service page.

Before you call either

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

Keycard

  1. Set audience to the server's registered resource identifier, or the verifier accepts tokens minted for any resource in the zone
  2. Check AccessContext.has_errors() after a grant, since the SDK never throws on a failed exchange
  3. Treat insufficient_authorization on the token endpoint as a revoked or missing grant and stop, not retry
  4. Keep credentials short-lived, because revocation only stops the next issuance
  5. Pin keycardai-mcp to a major version, since 1.0.0 and 2.0.0 shipped a day apart
