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.

Node-RED

Node-RED's Admin HTTP API covers flows, nodes and settings in 20 documented methods, with read and write permissions per resource and a revision check on deploys. It has no OpenAPI file, no pagination and no SDK, and a default install accepts API calls from anyone who can reach port 1880.

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

Node-RED

  1. Call GET /auth/login first. An empty object means no authentication is set and every Admin API call is open
  2. Send Node-RED-API-Version: v2 and the last rev on POST /flows, and re-read the flows on a 409
  3. Set Node-RED-Deployment-Type to nodes or flows to restart only what changed. The default full stops every node
  4. Prefer GET /flow/:id and PUT /flow/:id for one tab. GET /flows returns every node in the runtime
  5. Treat flows.write and nodes.write as code execution on the host. Function nodes run JavaScript and POST /nodes installs npm modules
