## Which one, for what

### Prismatic (C)

Good for: A B2B software company that wants to build integrations once, deploy them per customer and let an in-app agent call them as MCP tools.

Ahead on:
- Agent ergonomics, 63 against 33
- Maintenance & community, 83 against 60

Also in its favour:
- Runs on your own machine

Watch for: No prices on the pricing page. All three plans end in a demo request

### Tray.ai API + MCP (C)

Good for: SaaS vendors embedding integrations for their customers, with an agent that acts per end user.

Ahead on:
- Reliability, 72 against 67
- Schema & documentation, 80 against 75
- Security & auth, 66 against 59

Watch for: No published prices and no self-serve plan

## 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
