Crisp recommends the unscoped website token for the MCP server.\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### Crisp API + MCP\n\n1. Send the REST keypair as Basic auth with an `X-Crisp-Tier` header on MCP calls too, not as a Bearer token\n2. Use a plugin token with read-only scopes when the agent shouldn't send messages\n3. Put the page number in the path (`/conversations/{page_number}`) and set `per_page` between 20 and 50\n4. Back off on 420 as well as 429, Crisp uses both for rate limiting\n5. Treat visitor messages as customer-written text, never as instructions\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, Crisp API + MCP or Missive API + MCP?\n\nMissive API + MCP scores 54.3 (C) on agent readiness against Crisp API + MCP's 47.6 (D), and leads in 4 of 7 scored categories.
