## Which one, for what

### Pipedream API + MCP (B)

Good for: Best when an agent acts in many third-party apps on behalf of your own users and you don't want to run OAuth yourself.

Ahead on:
- Agent ergonomics, 73 against 63
- Payments & pricing, 40 against 0
- Transparency & trust, 75 against 65

Watch for: Public changelog's last entry is 1 October 2025

### 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.

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

## Verdicts

**Pipedream API + MCP.** Managed OAuth per end user across 3,000+ apps, through API, SDK or MCP. Public changelog's last entry is 1 October 2025.

**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

### Pipedream API + MCP

1. Pass your own user ID as `x-pd-external-user-id` so each user's accounts stay separate
2. Send `x-pd-app-slug` to load one app's tools rather than 10,000
3. Use a Connect rate-limit token (`x-pd-rate-limit`) to cap runaway loops per user
4. Check `isError` on tool results before treating a call as done
5. Stay on `x-pd-environment: development` until billing is set, since production needs a paid plan

### 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
