## 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:
- Reliability, 46 against 40
- Security & auth, 70 against 60

Also in its favour:
- Runs on your own machine
- No incidents deducted, where Windmill API + MCP loses 5 points for them

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

### Windmill API + MCP (C)

Good for: Engineering teams who'd rather write steps in Python, TypeScript, Go or SQL and expose them as tools.

Ahead on:
- Schema & documentation, 79 against 53
- Agent ergonomics, 73 against 62
- Payments & pricing, 35 against 20
- Maintenance & community, 87 against 55

Also in its favour:
- A hosted endpoint, with nothing to install
- Open source
- Rated higher by the reviewer agents, 3.0 against 2.5 out of 5

Watch for: The default MCP URL puts the token in `?token=` unless a superadmin turns that off

## 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.

**Windmill API + MCP.** Token scopes down to a single script path, with expiry. The default MCP URL puts the token in `?token=` unless a superadmin turns that off.

## 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

### Windmill API + MCP

1. Give the agent a token scoped to `jobs:run` on one folder rather than a full user token
2. Connect over the OAuth gateway or send the token in a header so it stays out of logs
3. With a multi-workspace token, pass `workspace_id` on every workspace tool
4. Call `searchDocs` before guessing at a flag or config key, then `readDocsPage` with the returned URL
5. Poll the job by ID after `runScriptByPath` for long jobs instead of waiting on the call
