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

## 🚀 Quick Start

### 1. Install from PyPI
```bash
pip install fast-mcp-telegram
```

### 2. Authenticate with Telegram
```bash
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):**
```json
{
  "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):**
```json
{
  "mcpServers": {
    "telegram": {
      "url": "https://your-server.com",
      "headers": {
        "Authorization": "Bearer AbCdEfGh123456789KLmnOpQr..."
      }
    }
  }
}
```

### 4. Start Using!
```json
// 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!"}}
```

## 🌐 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
```bash
# 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}}'
```
