Fast MCP Telegram Server - Production-ready Telegram integration for AI assistants with comprehensive search, messaging, and direct API access capabilities.

🌐 Demo

1. Open https://tg-mcp.l1979.ru/setup to begin the authentication flow.
2. After finishing, you'll receive a ready-to-use mcp.json with your Bearer token.
3. Use the config with your MCP client to check out this MCP server capabilities.
4. Or try the HTTP‑MTProto Bridge right away with curl (replace TOKEN):

curl -X POST "https://tg-mcp.l1979.ru/mtproto-api/messages.SendMessage" \
  -H "Authorization: Bearer TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"params": {"peer": "me", "message": "Hello from Demo!"}}'

🎯 Design Philosophy

Save context space for LLMs by making tools as general-purpose as possible. Fewer, more capable tools consume less of the AI's context window than many narrow-purpose tools. We consolidate functionality (e.g. get_messages handles search, browse, read-by-ID, and replies in one tool; invoke_mtproto provides raw API access for edge cases), use uniform schemas across tools so responses can be automatically processed when possible, and keep descriptions concise. We accept more parameters per tool and slightly more complex signatures in exchange for fewer tools and less context. When adding capabilities, we prefer extending existing tools over introducing new ones.

🛠️ Available Tools

📖 For detailed tool documentation with examples, see Tools Reference

🚀 Quick Start

1. Install from PyPI

pip install fast-mcp-telegram

2. Authenticate with Telegram

fast-mcp-telegram-setup --api-id="your_api_id" --api-hash="your_api_hash" --phone-number="+123456789"

🌐 Prefer a browser? Run the server and open /setup to authenticate and download a ready‑to‑use mcp.json. You can also reauthorize existing sessions through the same interface.

3. Configure Your MCP Client

STDIO Mode (Development with Cursor IDE):

{
  "mcpServers": {
    "telegram": {
      "command": "fast-mcp-telegram",
      "env": {
        "API_ID": "your_api_id",
        "API_HASH": "your_api_hash",
        "PHONE_NUMBER": "+123456789"
      }
    }
  }
}

HTTP_AUTH Mode (Production with Bearer Token):

{
  "mcpServers": {
    "telegram": {
      "url": "https://your-server.com",
      "headers": {
        "Authorization": "Bearer AbCdEfGh123456789KLmnOpQr..."
      }
    }
  }
}

4. Start Using!

// Global search across all chats
{"tool": "search_messages_globally", "params": {"query": "hello", "limit": 5}}

// Get latest messages from a chat
{"tool": "get_messages", "params": {"chat_id": "me", "limit": 10}}

// Search within a specific chat
{"tool": "get_messages", "params": {"chat_id": "@username", "query": "project"}}

// Read specific messages by ID
{"tool": "get_messages", "params": {"chat_id": "me", "message_ids": [123, 124]}}

// Get replies (channel posts, forum topics, or message replies)
{"tool": "get_messages", "params": {"chat_id": "-1001234567890", "reply_to_id": 42}}

// Send a message
{"tool": "send_message", "params": {"chat_id": "me", "message": "Hello from AI!"}}

🏗️ Server Modes

🌐 HTTP-MTProto Bridge

Direct curl access to any Telegram API method - Execute any Telegram MTProto method via HTTP requests with automatic entity resolution and safety guardrails.

Quick Examples

# Send message with automatic entity resolution
curl -X POST "https://your-domain.com/mtproto-api/messages.SendMessage" \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"params": {"peer": "@username", "message": "Hello from curl!"}}'

# Send message using params_json (works with n8n and other tools)
curl -X POST "https://your-domain.com/mtproto-api/messages.SendMessage" \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"params_json": "{\"peer\": \"@username\", \"message\": \"Hello from curl!\"}"}'

# Get message history with peer resolution
curl -X POST "https://your-domain.com/mtproto-api/messages.getHistory" \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"params": {"peer": "me", "limit": 10}}'
