Telegram MCP 服务器

Telegram MCP Server

🤖 MCP in Action

Here's a demonstration of the Telegram MCP capabilities in Claude:

Basic usage example:

Example: Asking Claude to analyze chat history and send a response:

Successfully sent message to the group:

As you can see, the AI can seamlessly interact with your Telegram account, retrieving and displaying your chats, messages, and other data in a natural way.

A full-featured Telegram integration for Claude, Cursor, and any MCP-compatible client, powered by Telethon and the Model Context Protocol (MCP). This project lets you interact with your Telegram account programmatically, automating everything from messaging to group management.

Removed Functionality

Please note that tools requiring direct file path access on the server (send_file, download_media, set_profile_photo, edit_chat_photo, send_voice, send_sticker, upload_file) have been removed from main.py. This is due to limitations in the current MCP environment regarding handling file attachments and local file system paths.

Additionally, GIF-related tools (get_gif_search, get_saved_gifs, send_gif) have been removed due to ongoing issues with reliability in the Telethon library or Telegram API interactions.

📋 Requirements

Python 3.10+
Telethon
MCP Python SDK
Claude Desktop or Cursor (or any MCP client)

🔧 Installation & Setup

1. Fork & Clone

git clone https://github.com/chigwell/telegram-mcp.git
cd telegram-mcp

2. Create a Virtual Environment

python3 -m venv .venv
source .venv/bin/activate  # On Windows: .venv\Scripts\activate
pip install -r requirements.txt

3. Generate a Session String

python3 session_string_generator.py

Follow the prompts to authenticate and update your .env file.

4. Configure .env

Copy .env.example to .env and fill in your values:

TELEGRAM_API_ID=your_api_id_here
TELEGRAM_API_HASH=your_api_hash_here
TELEGRAM_SESSION_NAME=anon
TELEGRAM_SESSION_STRING=your_session_string_here

Get your API credentials at my.telegram.org/apps.

🐳 Running with Docker

If you have Docker and Docker Compose installed, you can build and run the server in a container, simplifying dependency management.

1. Build the Image

From the project root directory, build the Docker image:

docker build -t telegram-mcp:latest .

2. Running the Container

You have two options:

Option A: Using Docker Compose (Recommended for Local Use)

This method uses the docker-compose.yml file and automatically reads your credentials from a .env file.

Create .env File: Ensure you have a .env file in the project root containing your TELEGRAM_API_ID, TELEGRAM_API_HASH, and TELEGRAM_SESSION_STRING (or TELEGRAM_SESSION_NAME). Use .env.example as a template.
Run Compose:
docker compose up --build
- Use docker compose up -d to run in detached mode (background).
- Press Ctrl+C to stop the server.

Option B: Using docker run

You can run the container directly, passing credentials as environment variables.

docker run -it --rm \
  -e TELEGRAM_API_ID="YOUR_API_ID" \
  -e TELEGRAM_API_HASH="YOUR_API_HASH" \
  -e TELEGRAM_SESSION_STRING="YOUR_SESSION_STRING" \
  telegram-mcp:latest

Replace placeholders with your actual credentials.
Use -e TELEGRAM_SESSION_NAME=your_session_file_name instead of TELEGRAM_SESSION_STRING if you prefer file-based sessions (requires volume mounting, see docker-compose.yml for an example).
The -it flags are crucial for interacting with the server.

⚙️ Configuration for Claude & Cursor

MCP Configuration

Edit your Claude desktop config (e.g. ~/Library/Application Support/Claude/claude_desktop_config.json) or Cursor config (~/.cursor/mcp.json):

{
  "mcpServers": {
    "telegram-mcp": {
      "command": "uv",
      "args": [
        "--directory",
        "/full/path/to/telegram-mcp",
        "run",
        "main.py"
      ]
    }
  }
}

📝 Tool Examples with Code & Output

Below are examples of the most commonly used tools with their implementation and sample output.

Getting Your Chats

@mcp.tool()
async def get_chats(page: int = 1, page_size: int = 20) -> str:
    """
    Get a paginated list of chats.
    Args:
        page: Page number (1-indexed).
        page_size: Number of chats per page.
    """
    try:
        dialogs = await client.get_dialogs()
        start = (page - 1) * page_size
        end = start + page_size
        if start >= len(dialogs):
            return "Page out of range."
        chats = dialogs[start:end]
        lines = []
        for dialog in chats:
            entity = dialog.entity
            chat_id = entity.id
            title = getattr(entity, "title", None) or getattr(entity, "first_name", "Unknown")
            lines.append(f"Chat ID: {chat_id}, Title: {title}")
        return "\n".join(lines)
    except Exception as e:
        logger.exception(f"get_chats failed (page={page}, page_size={page_size})")
        return "An error occurred (code: GETCHATS-ERR-001). Check mcp_errors.log for details."

Example output:

Chat ID: 123456789, Title: John Doe
Chat ID: -100987654321, Title: My Project Group
Chat ID: 111223344, Title: Jane Smith
Chat ID: -200123456789, Title: News Channel

Sending Messages

@mcp.tool()
async def send_message(chat_id: int, message: str) -> str:
    """
    Send a message to a specific chat.
    Args:
        chat_id: The ID of the chat.
        message: The message content to send.
    """
    try:
        entity = await client.get_entity(chat_id)
        await client.send_message(entity, message)
        return "Message sent successfully."
    except Exception as e:
        logger.exception(f"send_message failed (chat_id={chat_id})")
        return "An error occurred (code: SENDMSG-ERR-001). Check mcp_errors.log for details."

Example output:

Getting Chat Invite Links

The get_invite_link function is particularly robust with multiple fallback methods:

@mcp.tool()
async def get_invite_link(chat_id: int) -> str:
    """
    Get the invite link for a group or channel.
    """
    try:

            result = await client(functions.messages.ExportChatInviteRequest(
                peer=entity
            ))
            return result.link
        except AttributeError:
            # If the function doesn't exist in the current Telethon version
            logger.warning("ExportChatInviteRequest not available, using alternative method")
        except Exception as e1:

            logger.warning(f"ExportChatInviteRequest failed: {e1}")
            
        # Alternative approach using client.export_chat_invite_link
        try:
            invite_link = await client.export_chat_invite_link(entity)
            return invite_link
        except Exception as e2:
            logger.warning(f"export_chat_invite_link failed: {e2}")
            
        # Last resort: Try directly fetching chat info
        try:
            if isinstance(entity, (Chat, Channel)):
                full_chat = await client(functions.messages.GetFullChatRequest(
                    chat_id=entity.id
                ))
                if hasattr(full_chat, 'full_chat') and hasattr(full_chat.full_chat, 'invite_link'):
                    return full_chat.full_chat.invite_link or "No invite link available."
        except Exception as e3:
            logger.warning(f"GetFullChatRequest failed: {e3}")
            
        return "Could not retrieve invite link for this chat."
    except Exception as e:
        logger.exception(f"get_invite_link failed (chat_id={chat_id})")
        return f"Error getting invite link: {e}"

Joining Chats via Invite Links

@mcp.tool()
async def join_chat_by_link(link: str) -> str:
    """

    """
    try:

🧠 Error Handling & Robustness

This implementation includes comprehensive error handling:

Session management: Works with both file-based and string-based sessions
Error reporting: Detailed errors logged to mcp_errors.log
Graceful degradation: Multiple fallback approaches for critical functions
User-friendly messages: Clear, actionable error messages instead of technical errors
Account type detection: Functions that require bot accounts detect and notify when used with user accounts
Invite link processing: Handles various link formats and already-member cases

The code is designed to be robust against common Telegram API issues and limitations.

🛠️ Contribution Guide

Fork this repo: chigwell/telegram-mcp
Clone your fork:
git clone https://github.com/<your-github-username>/telegram-mcp.git
Create a new branch:
git checkout -b my-feature
Make your changes, add tests/docs if needed.
Push and open a Pull Request to chigwell/telegram-mcp with a clear description.
Tag @chigwell or @l1v0n1 in your PR for review.

🔒 Security Considerations

Never commit your .env or session string.
The session string gives full access to your Telegram account—keep it safe!
All processing is local; no data is sent anywhere except Telegram's API.
Use .env.example as a template and keep your actual .env file private.
Test files are automatically excluded in .gitignore.

🛠️ Troubleshooting

Check logs in your MCP client (Claude/Cursor) and the terminal for errors.
Detailed error logs can be found in mcp_errors.log.
Interpreter errors? Make sure your .venv is created and selected.
Database lock? Use session string authentication, not file-based sessions.
iCloud/Dropbox issues? Move your project to a local path without spaces if you see odd errors.
Regenerate session string if you change your Telegram password or see auth errors.
Bot-only functions will show clear messages when used with regular user accounts.
Test script failures? Check test configuration in .env for valid test accounts/groups.
