Verdicts

Paragon ActionKit + MCP

Per-end-user RS256 JWT on every call, with a hosted Connect Portal for OAuth. No published prices and no self-serve paid 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

Paragon ActionKit + MCP

  1. Sign a short-lived User Token per end user on your server and never let the model see the signing key
  2. Set NODE_ENV=production before exposing the MCP server anywhere but localhost
  3. Fetch the tool list once per session with categories set, and cache it
  4. Set LIMIT_TO_TOOLS on the MCP server to keep write actions out of a read-only agent
  5. Proxy API requests count as tasks, so prefer ActionKit tools for routine actions

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/
