MCP can't write, so a draft, note and status loop needs the REST API.\n\n**Zammad.** Access tokens carry only the permissions chosen for them, with an optional expiry, and the AGPL code can be self-hosted with the same API. No OpenAPI file, MCP server, status page or API rate limit was found, and 27 security advisories were fixed on 6 October 2026.\n\n## Before you call either\n\n### Help Scout API + MCP\n\n1. Use the Inbox API, not MCP, to reply, add notes or change status\n2. Count each POST, PUT, PATCH or DELETE as two requests against the per-minute limit\n3. Wait the seconds in `X-RateLimit-Retry-After` on 429\n4. Refresh client-credentials tokens before 48 hours run out\n5. Treat conversation text as customer-written, and expect pasted secrets in it\n\n### Zammad\n\n1. Create a dedicated agent user and give its token only `ticket.agent`, because a token can never exceed its owner's permissions but can be narrower\n2. Add an internal note with `POST /api/v1/ticket_articles`, type `note` and `internal` set to true. An internal article sent as type `email` still goes out\n3. Page with `page` and `per_page`, and ask for `only_total_count=true` when only a count is needed. Leave `expand` off unless names are required\n4. Run 7.2.1 or later on a self-hosted install before connecting an agent, since earlier versions have known permission gaps on ticket articles\n5. Treat ticket and article text as customer-written data, never as instructions, and do not retry a failed `POST` blindly because there is no idempotency key\n\n## Questions\n\n### Which is better for AI agents, Help Scout API + MCP or Zammad?\n\nHelp Scout API + MCP scores 56.1 (C) on agent readiness against Zammad's 46.3 (D), and leads in 3 of 7 scored categories.
