## Which one, for what

### Activepieces API + MCP (C)

Good for: A team that wants an MIT-licensed builder it can self-host or embed, with an agent that builds flows through MCP.

Ahead on:
- Schema & documentation, 80 against 75
- Security & auth, 64 against 59
- Payments & pricing, 35 against 0
- Transparency & trust, 73 against 65

Also in its favour:

Watch for: Docs say API keys come from the platform dashboard in Platform and Enterprise editions, while the pricing page lists the API on every plan

### 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 55

Also in its favour:
- Runs on your own machine
- No incidents deducted, where Activepieces API + MCP loses 6 points for them

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

## Verdicts

**Activepieces API + MCP.** MIT core, self-hostable, with the enterprise parts clearly separated. Docs say API keys come from the platform dashboard in Platform and Enterprise editions, while the pricing page lists the API on every plan.

**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

### Activepieces API + MCP

1. Run `ap_validate_flow` before publishing a flow
2. Use `ap_search_actions` with a plain task description rather than listing pieces
3. Turn off the Flow Building and Tables groups for a project the agent should only read
4. Page with `limit` and `cursor` and stop when `next` is null
5. Cloud runs stop at 10 minutes of active time. Waits and approvals don't count

### 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
