## 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

Also in its favour:
- Runs on your own machine
- No incidents deducted, where n8n API + MCP loses 12 points for them

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

### n8n API + MCP (D)

Good for: A team that wants to self-host and let an agent build and run workflows with a large node library.

Ahead on:
- Schema & documentation, 92 against 53
- Agent ergonomics, 75 against 62
- Payments & pricing, 30 against 20
- Maintenance & community, 80 against 55
- Transparency & trust, 80 against 65

Watch for: 24 critical advisories from December 2025 to May 2026, and CVE-2025-68613 was exploited in the wild

## 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.

**n8n API + MCP.** OpenAPI 3.0 spec with 208 operations, and Markdown docs plus llms.txt. 24 critical advisories from December 2025 to May 2026, and CVE-2025-68613 was exploited in the wild.

## 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

### n8n API + MCP

1. Check the instance version before trusting it. Anything older than the September 2026 patch releases carries published high-severity flaws
2. Ask for only the OAuth scopes the job needs. `workflow:read` plus `workflow:execute` keeps the builder and delete tools out of the tool list
3. Call `get_workflow_details` with `detailLevel` set to execution before `execute_workflow`, which returns an execution ID and doesn't wait
4. Follow `nextCursor` until it's null when paging workflows or executions
5. On Cloud trial accounts `/api/v1` won't answer. Use the MCP server or a paid plan
