**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
