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
