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
