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.

Tray.ai API + MCP

Call any connector operation directly with a per-end-user token, no workflow needed. No published prices and no self-serve plan.

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

Tray.ai API + MCP

  1. Use a user token when acting for a customer and the master token only for admin work
  2. Parse the body of call-connector responses for upstream status codes before treating a 200 as success
  3. Point Headless MCP at the workspace's region, api.eu1.tray.io or api.ap1.tray.io outside the US
  4. Pick the workspace at OAuth sign-in. Headless MCP binds it to the session and takes no workspace ID
  5. Ask before any Headless MCP delete. The server won't
