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.

Also in its favour

  • A hosted endpoint, with nothing to install

Watch for

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

Zoho Desk B

Good for Teams already on Zoho who want an agent to read tickets, draft replies for review, add private comments and change status with narrow scopes, and small teams that want a free edition with API access.

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.

Zoho Desk

Public OpenAPI 3.1 files cover 911 operations, OAuth scopes separate read, create, update and delete per module, and replies can be saved as drafts or sent for review before a customer sees them. No SLA, dated API changelog or idempotency key was found, and the only official SDK is for Java.

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

Zoho Desk

  1. Use the api_domain returned with the token. Each data centre has its own host, such as desk.zoho.com, desk.zoho.eu and desk.zoho.in
  2. Send Authorization: Zoho-oauthtoken <token> and refresh hourly. Put refresh parameters in the POST body, not the URL
  3. Create replies with POST /api/v1/tickets/{id}/draftReply, then sendDraft or sendForReview. sendReply emails the customer
  4. Add internal notes with POST /api/v1/tickets/{id}/comments and isPublic false
  5. Page with from and limit (50 at most). Deep offsets cost more credits, from 3 a call under 2,000 records to 100 above 100,000
