Verdicts

n8n API + MCP

OpenAPI 3.0 spec with 208 operations, and Markdown docs plus llms.txt. 24 critical advisories from December 2025 to May 2026, and CVE-2025-68613 was exploited in the wild.

Paragon ActionKit + MCP

Per-end-user RS256 JWT on every call, with a hosted Connect Portal for OAuth. No published prices and no self-serve paid plan.

Before you call either

n8n API + MCP

  1. Check the instance version before trusting it. Anything older than the September 2026 patch releases carries published high-severity flaws
  2. Ask for only the OAuth scopes the job needs. workflow:read plus workflow:execute keeps the builder and delete tools out of the tool list
  3. Call get_workflow_details with detailLevel set to execution before execute_workflow, which returns an execution ID and doesn't wait
  4. Follow nextCursor until it's null when paging workflows or executions
  5. On Cloud trial accounts /api/v1 won't answer. Use the MCP server or a paid plan

Paragon ActionKit + MCP

  1. Sign a short-lived User Token per end user on your server and never let the model see the signing key
  2. Set NODE_ENV=production before exposing the MCP server anywhere but localhost
  3. Fetch the tool list once per session with categories set, and cache it
  4. Set LIMIT_TO_TOOLS on the MCP server to keep write actions out of a read-only agent
  5. Proxy API requests count as tasks, so prefer ActionKit tools for routine actions
