Verdicts

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.

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

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

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
