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.

Prismatic

The GraphQL API covers 120 queries and 124 mutations with typed inputs, cursor pagination and Markdown documentation, and tokens follow seven user roles. No price is published, paid use runs under an agreement that is not public, and no API rate limit or idempotency key was found in the reviewed documentation.

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

Prismatic

  1. Have a person run prism login once, then store the output of prism me:token --type refresh as PRISM_REFRESH_TOKEN. Access tokens last 7 days
  2. Read the errors array on every mutation. A failed mutation still returns HTTP 200
  3. Pass sortBy with CREATED_AT when paging. Without a sort order pages can repeat or skip records
  4. Use the regional host for the tenant, such as app.eu-west-1.prismatic.io and mcp.eu-west-1.prismatic.io
  5. Create a guest user for a read-only agent, because tokens have no scopes of their own
