## Which one, for what

### Gumloop (C)

Good for: A team that wants hosted agents with connectors, approvals and triggers, driven or configured by an outside agent through the API or MCP server.

Ahead on:
- Reliability, 82 against 63
- Schema & documentation, 83 against 66
- Maintenance & community, 77 against 36

Watch for: API keys and the `gumloop_api` OAuth scope need the Pro plan at $37 a month. The 14-day trial needs a card

### Make API + MCP (C)

Good for: Teams who build in a visual editor and want an agent to run those scenarios as tools, cloud only.

Ahead on:
- Security & auth, 68 against 50
- Payments & pricing, 30 against 20
- Transparency & trust, 72 against 57

Also in its favour:
- Free to start without a card

Watch for: No published OpenAPI file and no official SDK

## 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.

**Make API + MCP.** Hosted MCP server with OAuth, and scenario run tools on the free plan. No published OpenAPI file and no official SDK.

## 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

### Make API + MCP

1. Find the organisation's zone first. It may be on make.com or make.celonis.com
2. Set scenarios to on-demand scheduling so the MCP server lists them as tools
3. Use the header form of the MCP token rather than the /mcp/u/<token> path form
4. On a 429, wait a full minute. The limit resets per minute and no Retry-After is sent
5. Check the `code` field on errors. IM002 means the token lacks rights, not that the resource is missing
