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
- Read the API Base URL and token from the tenant's Profile page. Tokens last 1 hour by default, so plan to refresh
- Send
X-Aembit-ResourceSeton Cloud API, Edge API and MCP calls outside the default Resource Set, or the request runs against the default set - Cache the Edge API access token from
/edge/v1/authuntil near expiry before calling/edge/v1/credentials. Both endpoints can answer 429 - Point MCP clients at
https://<gateway-host>/mcp. The/mepath is deprecated - Expect tool names prefixed with the Server Workload name behind the MCP Identity Gateway, and keep
perPageat 100 or less on the Aembit MCP Server
Scalekit AgentKit
- Use the exact dashboard Connection Name, not the connector slug, in every call
- Call
POST /api/v1/tools:searchwith top_k instead of listing every tool - When a connected account isn't ACTIVE, send the user the magic link and stop until they finish
- On ScalekitToolRateLimitException, back off before retrying, and log the executionId
- Mint a fresh virtual MCP session token per user per run and let it expire
