## Which one, for what

### Node-RED (C)

Good for: Owners who want event-driven flows on their own machine or device, with a large library of community nodes, and an agent that deploys or edits flows as JSON.

Ahead on:
- Reliability, 90 against 67
- Payments & pricing, 60 against 0

Also in its favour:
- Open source

Watch for: No OpenAPI file, `llms.txt` or SDK. The Admin API is documented as 20 hand-written pages on nodered.org

### 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:
- Schema & documentation, 75 against 41
- Agent ergonomics, 63 against 44
- Security & auth, 59 against 51

Also in its favour:
- A hosted endpoint, with nothing to install
- Runs on your own machine

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

## Verdicts

**Node-RED.** Node-RED's Admin HTTP API covers flows, nodes and settings in 20 documented methods, with read and write permissions per resource and a revision check on deploys. It has no OpenAPI file, no pagination and no SDK, and a default install accepts API calls from anyone who can reach port 1880.

**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

### Node-RED

1. Call `GET /auth/login` first. An empty object means no authentication is set and every Admin API call is open
2. Send `Node-RED-API-Version: v2` and the last `rev` on `POST /flows`, and re-read the flows on a 409
3. Set `Node-RED-Deployment-Type` to `nodes` or `flows` to restart only what changed. The default `full` stops every node
4. Prefer `GET /flow/:id` and `PUT /flow/:id` for one tab. `GET /flows` returns every node in the runtime
5. Treat `flows.write` and `nodes.write` as code execution on the host. Function nodes run JavaScript and `POST /nodes` installs npm modules

### 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
