## Which one, for what

### Make API + MCP (C)

Good for: Teams who build in a visual editor and want an agent to run those scenarios as tools, cloud only.

Ahead on:
- Security & auth, 68 against 61
- Payments & pricing, 30 against 25

Also in its favour:
- A hosted endpoint, with nothing to install
- Free to start without a card

Watch for: No published OpenAPI file and no official SDK

### 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:
- Agent ergonomics, 69 against 63
- Maintenance & community, 76 against 36

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

## Verdicts

**Make API + MCP.** Hosted MCP server with OAuth, and scenario run tools on the free plan. No published OpenAPI file and no official SDK.

**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

### Make API + MCP

1. Find the organisation's zone first. It may be on make.com or make.celonis.com
2. Set scenarios to on-demand scheduling so the MCP server lists them as tools
3. Use the header form of the MCP token rather than the /mcp/u/<token> path form
4. On a 429, wait a full minute. The limit resets per minute and no Retry-After is sent
5. Check the `code` field on errors. IM002 means the token lacks rights, not that the resource is missing

### 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/`
