## 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 66

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

### Scalekit AgentKit (BB)

Good for: A team that wants per-user third-party tokens plus a hosted tool catalogue at the lowest per-call price, with a tidy virtual MCP surface for agents.

Ahead on:
- Reliability, 75 against 65
- Agent ergonomics, 83 against 72
- Transparency & trust, 65 against 60

Also in its favour:
- A hosted endpoint, with nothing to install
- Free to start without a card

Watch for: No rate limits or idempotency documented for Scalekit's own API

## 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.

**Scalekit AgentKit.** 500+ connectors, including remote MCP servers over OAuth 2.1 with DCR. No rate limits or idempotency documented for Scalekit's own API.

## 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

### Scalekit AgentKit

1. Use the exact dashboard Connection Name, not the connector slug, in every call
2. Call `POST /api/v1/tools:search` with top_k instead of listing every tool
3. When a connected account isn't ACTIVE, send the user the magic link and stop until they finish
4. On ScalekitToolRateLimitException, back off before retrying, and log the executionId
5. Mint a fresh virtual MCP session token per user per run and let it expire
