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.

Prismatic

The GraphQL API covers 120 queries and 124 mutations with typed inputs, cursor pagination and Markdown documentation, and tokens follow seven user roles. No price is published, paid use runs under an agreement that is not public, and no API rate limit or idempotency key was found in the reviewed documentation.

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

Prismatic

  1. Have a person run prism login once, then store the output of prism me:token --type refresh as PRISM_REFRESH_TOKEN. Access tokens last 7 days
  2. Read the errors array on every mutation. A failed mutation still returns HTTP 200
  3. Pass sortBy with CREATED_AT when paging. Without a sort order pages can repeat or skip records
  4. Use the regional host for the tenant, such as app.eu-west-1.prismatic.io and mcp.eu-west-1.prismatic.io
  5. Create a guest user for a read-only agent, because tokens have no scopes of their own
