## Verdicts

**Activepieces API + MCP.** MIT core, self-hostable, with the enterprise parts clearly separated. Docs say API keys come from the platform dashboard in Platform and Enterprise editions, while the pricing page lists the API on every plan.

**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

### Activepieces API + MCP

1. Run `ap_validate_flow` before publishing a flow
2. Use `ap_search_actions` with a plain task description rather than listing pieces
3. Turn off the Flow Building and Tables groups for a project the agent should only read
4. Page with `limit` and `cursor` and stop when `next` is null
5. Cloud runs stop at 10 minutes of active time. Waits and approvals don't count

### 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
