## 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:
- Security & auth, 84 against 67

Also in its favour:
- Agent-ready, a grade of BB or better
- No incidents deducted, where Nango loses 5 points for them

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

### Nango (B)

Good for: A product that connects many users to many SaaS APIs and wants tokens, refresh, syncs and a per-tenant MCP surface in one place, with source you can read.

Ahead on:
- Reliability, 78 against 65
- Maintenance & community, 90 against 80
- Transparency & trust, 76 against 60

Also in its favour:
- A hosted endpoint, with nothing to install

Watch for: Audit trail only on Enterprise, and logs kept 15 days on every plan

## 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.

**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.

## 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

### 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
