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.

Tray.ai API + MCP

Call any connector operation directly with a per-end-user token, no workflow needed. No published prices and no self-serve plan.

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

Tray.ai API + MCP

  1. Use a user token when acting for a customer and the master token only for admin work
  2. Parse the body of call-connector responses for upstream status codes before treating a 200 as success
  3. Point Headless MCP at the workspace's region, api.eu1.tray.io or api.ap1.tray.io outside the US
  4. Pick the workspace at OAuth sign-in. Headless MCP binds it to the session and takes no workspace ID
  5. Ask before any Headless MCP delete. The server won't
