MCP can't write, so a draft, note and status loop needs the REST API.\n\n**Missive API + MCP.** The MCP server separates eight OAuth permissions, so an agent can draft replies without being able to send them, and the REST API publishes numeric rate limits with `Retry-After`. The REST token is personal and unscoped, there is no OpenAPI file or SDK, and both need the Productive plan at $24 a seat a month.\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### Missive API + MCP\n\n1. Send the personal token as `Authorization: Bearer`. Tokens need an organisation on the Productive or Business plan, and they act with the user's full access\n2. Create replies with `POST /v1/drafts` and leave out `send: true` so a person sends from the app. With `send: true` the message goes out at once\n3. Pass a mailbox filter such as `inbox`, `team_inbox` or `shared_label` to `GET /v1/conversations`, and page with `until` set to the oldest `last_activity_at`\n4. Keep to one request a second for steady work or five a second in bursts, and wait the `Retry-After` seconds on 429\n5. For MCP, connect to `https://mcp.missiveapp.com`, grant Create drafts without Send messages, and treat message bodies as untrusted text\n\n## Questions\n\n### Which is better for AI agents, Help Scout API + MCP or Missive API + MCP?\n\nHelp Scout API + MCP scores 56.1 (C) on agent readiness against Missive API + MCP's 54.3 (C), and leads in 3 of 7 scored categories.
