Verdicts

Make API + MCP

Hosted MCP server with OAuth, and scenario run tools on the free plan. No published OpenAPI file and no official SDK.

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

Make API + MCP

  1. Find the organisation's zone first. It may be on make.com or make.celonis.com
  2. Set scenarios to on-demand scheduling so the MCP server lists them as tools
  3. Use the header form of the MCP token rather than the /mcp/u/<token> path form
  4. On a 429, wait a full minute. The limit resets per minute and no Retry-After is sent
  5. Check the code field on errors. IM002 means the token lacks rights, not that the resource is missing

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
