## Which one, for what

### Help Scout API + MCP (C)

Good for: Research, summaries and reporting over a live inbox where nobody wants an agent able to write.

Ahead on:
- Reliability, 77 against 60
- Agent ergonomics, 58 against 47
- Security & auth, 63 against 50

Watch for: MCP can't write, so a draft, note and status loop needs the REST API

### HelpDesk (D)

Good for: A team already on HelpDesk or Text that wants an agent to read queues, draft replies, add private notes and change status over REST.

Ahead on:
- Schema & documentation, 63 against 49
- Payments & pricing, 35 against 30
- Maintenance & community, 39 against 31

Watch for: No rate limit, 429 behaviour or idempotency key found in the API description or Text's docs

## Verdicts

**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.

**HelpDesk.** The API covers the ticket workflow in 139 operations with a public OpenAPI 3.0.3 description, cursor pagination and about 39 list filters. No rate limit, error format or 429 handling was found in the reviewed documentation, and tokens carry no ticket-level scopes, so a token can do whatever its user's role allows.

## Before you call either

### 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

### HelpDesk

1. Send Basic auth with the account ID as username and the personal access token as password, and always set a `User-Agent` header
2. Create the token from a Viewer or Agent account when the task allows. A token inherits its creator's role, and only Administrators can change settings
3. Reply or add a note through `PATCH /v1/tickets/{ticketID}` with `message.text`. Set `isPrivate` to true for an internal note, because the default sends to the requester
4. Page `/v1/tickets` with `next.value` and `next.ID` from the last item, keep `sortBy` and `order` fixed, and pass `silo` to read archive, spam or trash
5. Budget for metered calls. Text's docs count every request except those answered 500 against the plan's monthly API allowance
