Verdicts

Gumloop

Gumloop's REST API has a public OpenAPI file with 105 operations, Markdown docs and a changelog with 28 dated releases since 9 July 2026. API keys need the $37 Pro plan, the trial needs a card, the key can travel in the URL, and self-serve content may be used to train Gumloop's models.

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

Gumloop

  1. Send the key as Authorization: Bearer and, for a personal key, add the x-auth-key header with the user ID. Do not put api_key in the URL
  2. Create sessions with POST /agents/{agent_id}/sessions, then poll GET /sessions/{session_id}. A 202 means processing or queued, and the reply is not in the response
  3. Supply your own session_id when creating a session. A repeat returns 409, which makes a retry safe
  4. For streamed output send the same body with stream: true to ws.gumloop.com. api.gumloop.com answers 400 to it
  5. Treat a webhook trigger URL as a password. It returns {"success": true} at once and never carries the agent's output

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
