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/
