## 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:
- Security & auth, 70 against 59
- Payments & pricing, 20 against 0

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

### Prismatic (C)

Good for: A B2B software company that wants to build integrations once, deploy them per customer and let an in-app agent call them as MCP tools.

Ahead on:
- Reliability, 67 against 46
- Schema & documentation, 75 against 53
- Maintenance & community, 83 against 55

Also in its favour:
- A hosted endpoint, with nothing to install

Watch for: No prices on the pricing page. All three plans end in a demo request

## 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
