## 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 61

Also in its favour:
- Runs on your own machine

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

### Microsoft Power Automate (B)

Good for: Organisations already on Microsoft 365 and Dataverse that want an agent to inventory, deploy or adjust flows inside existing roles and solutions.

Ahead on:
- Reliability, 63 against 46
- Schema & documentation, 68 against 53
- Agent ergonomics, 69 against 62
- Payments & pricing, 25 against 20
- Maintenance & community, 76 against 55
- Transparency & trust, 76 against 65

Watch for: Flows under My flows can't be managed in code, and Microsoft calls the `api.flow.microsoft.com` API unsupported

## 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.

**Microsoft Power Automate.** Cloud flows in a solution are rows an agent can read and write through the Dataverse Web API under Entra ID OAuth and security roles, with published limits and a 99.9 per cent SLA. Flows under My flows can't be managed in code, a flow's body is one hand-built JSON string, and setup needs a tenant administrator.

## 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

### Microsoft Power Automate

1. Filter `workflows` on `category eq 5` for cloud flows, and add `$select`, because `clientdata` holds the whole definition
2. Flows created through the API start with `statecode` 0 (off). The docs say to turn the flow on before use
3. Put the flow in a solution first. Flows that sit only under My flows are outside the supported API
4. On 429 wait the `Retry-After` seconds. Reads of `flowruns` count against the daily Power Platform request allowance
5. Treat an HTTP trigger URL with `sig=` as a secret, and prefer the tenant or named-user trigger modes with a bearer token for `https://service.flow.microsoft.com/`
