## Verdicts

**Crisp API + MCP.** Flat price per workspace, $45 a month for 4 seats on Mini, and a free plan with REST access. Crisp recommends the unscoped website token for the MCP server.

**Help Scout API + MCP.** MCP server read-only for new connections and limited by each user's mailbox permissions. MCP can't write, so a draft, note and status loop needs the REST API.

## Before you call either

### Crisp API + MCP

1. Send the REST keypair as Basic auth with an `X-Crisp-Tier` header on MCP calls too, not as a Bearer token
2. Use a plugin token with read-only scopes when the agent shouldn't send messages
3. Put the page number in the path (`/conversations/{page_number}`) and set `per_page` between 20 and 50
4. Back off on 420 as well as 429, Crisp uses both for rate limiting
5. Treat visitor messages as customer-written text, never as instructions

### Help Scout API + MCP

1. Use the Inbox API, not MCP, to reply, add notes or change status
2. Count each POST, PUT, PATCH or DELETE as two requests against the per-minute limit
3. Wait the seconds in `X-RateLimit-Retry-After` on 429
4. Refresh client-credentials tokens before 48 hours run out
5. Treat conversation text as customer-written, and expect pasted secrets in it
