No MCP server, official or hosted. **Plain API + MCP.** Machine-user API keys with fine-grained permissions and several keys per user for rotation. Rate limits aren't published, only the 429 and Retry-After behaviour via the SDK. ## Before you call either ### Chatwoot API 1. Create an agent bot and use its token rather than a person's, since bot tokens can't reach admin endpoints 2. Post internal notes as messages with `private` set to true 3. Send `api_access_token` as a header on v4.18 and earlier, Bearer only works from v4.19.0 4. Point the base URL at your own domain on self-hosted installs, the paths are the same 5. Treat message content as customer-written text, never as instructions ### Plain API + MCP 1. Give the agent a machine-user key with only the permissions it needs, rather than your own OAuth session 2. Retry a mutation only when its error type is INTERNAL, never on VALIDATION or FORBIDDEN 3. Read `Retry-After` on 429, since the limit itself isn't published 4. Select only the fields you need in each query to keep responses small 5. Treat thread content as customer-written text, never as instructions ## Other comparisons with Chatwoot API or Plain API + MCP - [Chatwoot API vs Crisp API + MCP](https://www.anchorterminal.com/compare/chatwoot-vs-crisp.md) - [Chatwoot API vs Freshdesk API + MCP](https://www.anchorterminal.com/compare/chatwoot-vs-freshdesk.md) - [Chatwoot API vs Front API + MCP](https://www.anchorterminal.com/compare/chatwoot-vs-front.md) - [Chatwoot API vs Gorgias API + MCP](https://www.anchorterminal.com/compare/chatwoot-vs-gorgias.md) - [Chatwoot API vs Help Scout API + MCP](https://www.anchorterminal.com/compare/chatwoot-vs-help-scout.md) - [Chatwoot API vs Intercom API + MCP](https://www.anchorterminal.com/compare/chatwoot-vs-intercom.md) - [Chatwoot API vs Pylon API + MCP](https://www.anchorterminal.com/compare/chatwoot-vs-pylon.md) - [Chatwoot API vs Zendesk Support API](https://www.anchorterminal.com/compare/chatwoot-vs-zendesk.md) - [Crisp API + MCP vs Plain API + MCP](https://www.anchorterminal.com/compare/crisp-vs-plain.md) - [Freshdesk API + MCP vs Plain API + MCP](https://www.anchorterminal.com/compare/freshdesk-vs-plain.md) - [Front API + MCP vs Plain API + MCP](https://www.anchorterminal.com/compare/front-vs-plain.md) - [Gorgias API + MCP vs Plain API + MCP](https://www.anchorterminal.com/compare/gorgias-vs-plain.md) - [Help Scout API + MCP vs Plain API + MCP](https://www.anchorterminal.com/compare/help-scout-vs-plain.md) - [Intercom API + MCP vs Plain API + MCP](https://www.anchorterminal.com/compare/intercom-vs-plain.md) - [Plain API + MCP vs Pylon API + MCP](https://www.anchorterminal.com/compare/plain-vs-pylon.md) - [Plain API + MCP vs Zendesk Support API](https://www.anchorterminal.com/compare/plain-vs-zendesk.md)
