## 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:
- Reliability, 67 against 58
- Schema & documentation, 75 against 63
- Agent ergonomics, 63 against 51
- 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

### Workato API + MCP (C)

Good for: Large companies that already run Workato and want agents inside its governance (roles, audit, per-user credentials).

Ahead on:
- Security & auth, 70 against 59
- Payments & pricing, 35 against 0

Watch for: No OpenAPI file and no official SDK on npm or PyPI

## 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
