  • Schema & documentation, 68 against 63
  • Agent ergonomics, 69 against 51
  • Maintenance & community, 76 against 60

Verdicts

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.

Workato API + MCP

API client tokens scoped by role and project, with legacy full-access keys removed on 14 October 2025. No OpenAPI file and no official SDK on npm or PyPI.

Before you call either

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/

Workato API + MCP

  1. Use the base URL for the workspace's data centre, and app.trial.workato.com for Free or Pro
  2. Give the agent an API client whose role lists only the endpoints it needs. The MCP server exposes those as tools
  3. Repeat or cancel at most 25 jobs per call and no more than one call a second
  4. Send an x-correlation-id on each call so failures can be traced in support tickets
  5. Every action step in a recipe is a task, so collapse loops before running at volume
