## Which one, for what

### Microsoft Copilot Studio MCP (D)

Good for: Teams already on Copilot Studio that want a coding agent or CLI to build, test, deploy and monitor Copilot Studio agents and workflows, and to set up their connectors.

Ahead on:
- Security & auth, 70 against 50
- Transparency & trust, 65 against 57

Also in its favour:
- Runs on your own machine

Watch for: First published on 16 October 2026, with two releases and no release notes or changelog

### 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 46
- Schema & documentation, 83 against 53
- Maintenance & community, 77 against 55

Also in its favour:
- A hosted endpoint, with nothing to install

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

## Verdicts

**Microsoft Copilot Studio MCP.** Entra sign-in with per-resource scopes, tokens kept only in memory, and a plan-then-confirm step before connector writes. The package is a day old, the linked MIT repository holds no source, no changelog or support channel exists, the five cloud tools' schemas are visible only after sign-in, and workflow tests run live workflows billed in Copilot Credits.

**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.

## Before you call either

### Microsoft Copilot Studio MCP

1. Call `copilot_studio_status` first and reuse a ready session. Don't reconnect or reselect an environment to start a new task
2. Read an action's contract with `discover_resources` and `action=describe_actions` before building unfamiliar `parameters`
3. Ask the person before testing a workflow. Tests run published, enabled workflows and can have real effects
4. Never retry an uncertain write. Inspect the agent, workflow or connection first, as the error text says
5. Expect a browser sign-in after every restart. Tell the person a window is opening and never ask for credentials in chat

### 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
