Verdicts

Aembit

Agents and workloads get short-lived credentials by attestation, and MCP clients sign in through OAuth 2.1 with policy checked on every request. Both APIs have public OpenAPI files. No rate limit figures or SLA are published, the managed gateway endpoint is requested through an Aembit representative, and no DPA or sub-processor list was found.

Auth0 for AI Agents (Token Vault)

Standard grants throughout, RFC 8693 token exchange, CIBA with RAR and DPoP. Only works when Auth0 is the identity provider for your users.

Before you call either

Aembit

  1. Read the API Base URL and token from the tenant's Profile page. Tokens last 1 hour by default, so plan to refresh
  2. Send X-Aembit-ResourceSet on Cloud API, Edge API and MCP calls outside the default Resource Set, or the request runs against the default set
  3. Cache the Edge API access token from /edge/v1/auth until near expiry before calling /edge/v1/credentials. Both endpoints can answer 429
  4. Point MCP clients at https://<gateway-host>/mcp. The /me path is deprecated
  5. Expect tool names prefixed with the Server Workload name behind the MCP Identity Gateway, and keep perPage at 100 or less on the Aembit MCP Server

Auth0 for AI Agents (Token Vault)

  1. Turn off refresh token rotation on the application before using the refresh token exchange
  2. Treat a 401 from the exchange as a missing connected account and send the user through the Connected Accounts flow
  3. Pass login_hint when a user has linked two accounts from the same provider
  4. Use CIBA for purchases or deletes and wait for the approval instead of asking in chat
  5. Read X-RateLimit-Reset on a 429 and back off until then
