Which one, for what

Aembit BB

Good for A security team that wants one policy and audit point between AI agents or workloads and the services they call, with credentials kept away from the agent.

Ahead on

  • Schema & documentation, 85 against 78
  • Maintenance & community, 80 against 74

Watch for

No rate limit figures in the reviewed documentation. The Edge API lists 429 responses without limits or Retry-After guidance

Descope Agentic Identity Hub A

Good for A team that wants one vendor for both directions, holding users' third-party tokens and acting as the authorisation server for its own MCP server, with policy per agent.

Ahead on

  • Reliability, 100 against 65
  • Agent ergonomics, 80 against 72
  • Transparency & trust, 67 against 60

Also in its favour

  • A hosted endpoint, with nothing to install
  • Free to start without a card

Watch for

No tool catalogue, so you write every provider call yourself

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.

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.

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

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, since the Agent Auth SDK's own retry waits under a second
  4. Ask for a tenant token, not a user token, for organisation-wide API keys
  5. Install the Agent Auth SDK from github.com/descope/descope-agent-auth, since pip install descope-agent-auth and npm install @descope/agent-auth fail because neither package is published
