## Which one, for what

### Activepieces API + MCP (C)

Good for: A team that wants an MIT-licensed builder it can self-host or embed, with an agent that builds flows through MCP.

Ahead on:
- Schema & documentation, 80 against 68
- Payments & pricing, 35 against 25

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

Watch for: Docs say API keys come from the platform dashboard in Platform and Enterprise editions, while the pricing page lists the API on every plan

### 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 55

Also in its favour:
- No incidents deducted, where Activepieces API + MCP loses 6 points for them

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

## Verdicts

**Activepieces API + MCP.** MIT core, self-hostable, with the enterprise parts clearly separated. Docs say API keys come from the platform dashboard in Platform and Enterprise editions, while the pricing page lists the API on every plan.

**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

### Activepieces API + MCP

1. Run `ap_validate_flow` before publishing a flow
2. Use `ap_search_actions` with a plain task description rather than listing pieces
3. Turn off the Flow Building and Tables groups for a project the agent should only read
4. Page with `limit` and `cursor` and stop when `next` is null
5. Cloud runs stop at 10 minutes of active time. Waits and approvals don't count

### 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/`
