Does CRMChat work as a Telegram MCP server?

Yes. CRMChat exposes an LLM-optimized index at /llms.txt and a full OpenAPI 3.x spec at /v1/spec.json, making it compatible with Model Context Protocol clients like Claude, Cursor, and Copilot. You can load the entire CRMChat API context directly into your AI coding agent and interact with Telegram contacts, campaigns, and webhooks through natural language or generated code — no manual API mapping required.
