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. Ahead on: - Schema & documentation, 72 against 49 - Agent ergonomics, 67 against 58 - Payments & pricing, 40 against 30 - Maintenance & community, 63 against 31 - Transparency & trust, 79 against 66 Also in its favour: - Free to start without a card Watch for: No SLA found, and the Terms of Service disclaim uninterrupted service ## Score by category | Category | Weight | Help Scout API + MCP | Zoho Desk | Edge | | --- | --- | --- | --- | --- | | Reliability | 16% (20 this run) | 77 | 75 | Help Scout API + MCP +2 | | Performance | 10%, pending | pending | pending | not scored in this run | | Schema & documentation | 13% (16.2 this run) | 49 | 72 | Zoho Desk +23 | | Agent ergonomics | 13% (16.2 this run) | 58 | 67 | Zoho Desk +9 | | Security & auth | 14% (17.5 this run) | 63 | 66 | Zoho Desk +3 | | Payments & pricing | 10% (12.5 this run) | 30 | 40 | Zoho Desk +10 | | Task success | 10%, pending | pending | pending | not scored in this run | | Maintenance & community | 7% (8.8 this run) | 31 | 63 | Zoho Desk +32 | | Transparency & trust | 7% (8.8 this run) | 66 | 79 | Zoho Desk +13 | | Negative events | ≤15 | 0 | 0 | | | **Total** | | **56.1 · C** | **66.6 · B** | | ## Facts side by side | Fact | Help Scout API + MCP | Zoho Desk | | --- | --- | --- | | Kind | HTTP API | HTTP API | | Vendor | Help Scout | Zoho | | Hosted endpoint | `https://api.helpscout.net/v2` | no (local only) | | Transports | HTTP, Streamable HTTP | HTTP | | Auth | OAuth | OAuth | | Pricing | Freemium | Freemium | | x402 | no | no | | Licence | none | Proprietary service under Zoho's Terms of Service.

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 ` 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 ## Questions ### Which is better for AI agents, Help Scout API + MCP or Zoho Desk?
