Verdicts

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.

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

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

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
