An MCP (Model Context Protocol) server that enables Claude Code to send and receive messages via Telegram. This allows you to interact with Claude Code remotely through your Telegram app.

## Features

- Send text messages from Claude Code to Telegram
- Receive messages from Telegram in Claude Code
- Send photos/screenshots to Telegram
- Proxy support for regions where Telegram is blocked
- **NEW: Remote permission approval via hooks** - Approve/deny sensitive operations from your phone
- **NEW: Lock file mechanism** - Prevents multiple instance conflicts

## Prerequisites

- [Node.js](https://nodejs.org/) 18.0.0 or higher
- [Claude Code](https://claude.ai/code) installed
- A Telegram account

## Quick Start

### Step 1: Create a Telegram Bot

1. Open Telegram and search for [@BotFather](https://t.me/BotFather)
2. Send `/newbot` command
3. Follow the prompts to name your bot
4. **Save the bot token** - it looks like: `1234567890:ABCdefGHIjklMNOpqrsTUVwxyz`

### Step 2: Get Your Chat ID

1. Open Telegram and search for [@userinfobot](https://t.me/userinfobot)
2. Send any message to this bot
3. **Save the `Id` value** from the response - it looks like: `123456789`

### Step 3: Start Your Bot

**Important:** Before Claude Code can receive your messages, you must start a conversation with your bot:
1. Search for your bot by its username in Telegram
2. Click "Start" or send any message to it

### Step 4: Configure Claude Code

Add the MCP server to your Claude Code configuration.

**Option A: Using Claude Code settings command**
```bash
claude /settings
```
Then add the MCP server configuration.

**Option B: Edit configuration file directly**

The configuration file is located at:
- Windows: `%USERPROFILE%\.claude.json`
- macOS/Linux: `~/.claude.json`

## Configuration Examples

### Without Proxy

If you can access Telegram directly:

```json
{
  "mcpServers": {
    "telegram": {
      "command": "npx",
      "args": ["-y", "mcp-telegram-claudecode"],
      "env": {
        "TELEGRAM_BOT_TOKEN": "1234567890:ABCdefGHIjklMNOpqrsTUVwxyz",
        "TELEGRAM_CHAT_ID": "123456789"
      }
    }
  }
}
```

### With Proxy

If you need a proxy to access Telegram:

```json
{
  "mcpServers": {
    "telegram": {
      "command": "npx",
      "args": ["-y", "mcp-telegram-claudecode"],
      "env": {
        "TELEGRAM_BOT_TOKEN": "1234567890:ABCdefGHIjklMNOpqrsTUVwxyz",
        "TELEGRAM_CHAT_ID": "123456789",
        "HTTP_PROXY": "http://127.0.0.1:7890"
      }
    }
  }
}
```

**Common proxy ports:**
- Clash: `http://127.0.0.1:7890`
- V2Ray: `http://127.0.0.1:10808`
- Shadowsocks: `http://127.0.0.1:1080`

Replace with your actual proxy address and port.

## Environment Variables

| Variable | Required | Description |
|----------|----------|-------------|
| `TELEGRAM_BOT_TOKEN` | Yes | Bot token from @BotFather |
| `TELEGRAM_CHAT_ID` | Yes | Your chat ID from @userinfobot |
| `HTTP_PROXY` | No | HTTP proxy URL (e.g., `http://127.0.0.1:7890`) |
| `HTTPS_PROXY` | No | HTTPS proxy URL (alternative to HTTP_PROXY) |

---

## Available Tools

Once configured, Claude Code will have access to these tools:

### telegram_send_message
Send a text message to your Telegram.
```
Parameters:
- message (required): The text message to send
```

### telegram_get_messages
Retrieve recent messages from Telegram.
```
Parameters:
- limit (optional): Maximum number of messages to retrieve (default: 10)
```

### telegram_check_new
Quick check if there are new messages.
```
No parameters required
```

### telegram_send_photo
Send an image file to Telegram.
```
Parameters:
- photo_path (required): Absolute path to the image file
- caption (optional): Caption for the photo
```

---

## Usage Examples

After configuration, you can ask Claude Code to:

- "Send me a message on Telegram saying the task is complete"
- "Check if I sent any new messages on Telegram"
- "Send a screenshot of the current code to my Telegram"

---

## Troubleshooting

### "TELEGRAM_BOT_TOKEN must be configured"
Make sure you've added the bot token to your `.claude.json` configuration.

### "No new messages" but you sent messages
1. Make sure you started a conversation with your bot first
2. Check that your `TELEGRAM_CHAT_ID` is correct
3. If using a proxy, verify the proxy is working

### Connection timeout or network error
If you're in a region where Telegram is blocked:
1. Make sure your proxy software is running
2. Add the `HTTP_PROXY` environment variable to your configuration
3. Verify the proxy port is correct

### Bot not responding
1. Check that the bot token is correct (no extra spaces)
2. Make sure you've started a conversation with your bot
3. Try sending a message to your bot first, then check for messages

## Remote Permission Approval (Recommended)

Instead of using `--dangerously-skip-permissions`, you can use Claude Code hooks to approve sensitive operations remotely via Telegram.

### How It Works

```
┌─────────────┐     PreToolUse Hook     ┌─────────────────┐     Telegram API     ┌──────────┐
│ Claude Code │ ──────────────────────► │ Hook Script     │ ◄─────────────────► │ Telegram │
│ (sensitive  │                         │ (asks approval) │                      │ (you)    │
│  operation) │ ◄────────────────────── │                 │                      │          │
└─────────────┘     approve/deny        └─────────────────┘                      └──────────┘
```

1. Claude Code attempts a sensitive operation (Edit, Write, Bash)
2. PreToolUse hook sends details to your Telegram
3. You reply **Y** to approve or **N** to deny
4. Hook returns the decision to Claude Code

### Setup

1. Copy the hooks to your system (included in `hooks/` directory)
2. Configure Claude Code hooks via `/hooks` command or edit settings:

```json
{
  "hooks": {
    "PreToolUse": [
      {
        "matcher": "Bash|Edit|Write",
        "hooks": [
          "node /path/to/telegram-claude-mcp/hooks/pretool-approval.js"
        ]
      }
    ]
  }
}
```

3. Set environment variables (same as MCP server config)

See [hooks/README.md](hooks/README.md) for detailed setup instructions.

### Approval Responses

| Approve | Deny |
|---------|------|
| Y, yes, 1, approve | N, no, 0, deny |
| 是, 好, 可以 | 否, 不, 拒绝 |

---

## How It Works

### Architecture

This MCP server acts as a bridge between Claude Code and Telegram:

```
┌─────────────┐     MCP Protocol      ┌─────────────────┐     Telegram API     ┌──────────┐
│ Claude Code │ ◄──────────────────► │ MCP Server      │ ◄─────────────────► │ Telegram │
│             │                       │ (this project)  │                      │          │
└─────────────┘                       └─────────────────┘                      └──────────┘
```

### Auto-Polling & Terminal Injection (Experimental)

When the MCP server starts, it automatically begins polling for new Telegram messages. When a message is received, it attempts to inject the text into the active terminal window using:

1. **Clipboard**: Message is copied to system clipboard
2. **SendKeys (Windows)**: PowerShell script simulates Ctrl+V and Enter keystrokes
3. **Window Activation**: Attempts to find and activate terminal windows (Windows Terminal, cmd, PowerShell, VS Code)

**This is an experimental feature** - it enables "remote control" of Claude Code via Telegram, but has reliability limitations.

### Tools Available

| Tool | Description |
|------|-------------|
| `telegram_send_message` | Send text to Telegram |
| `telegram_get_messages` | Retrieve recent messages |
| `telegram_check_new` | Quick check for new messages |
| `telegram_send_photo` | Send images to Telegram |
| `telegram_start_polling` | Manually start auto-polling |
| `telegram_stop_polling` | Stop auto-polling |

## Known Issues & Limitations

### ✅ Multiple Claude Code Instances (Fixed in v1.4.0)

**Problem**: If you run multiple Claude Code windows, each will start its own MCP server instance.

**Solution**: Lock file mechanism now prevents multiple instances from polling simultaneously. Only the first instance will poll; others will skip polling automatically.

### ✅ Injection Failure Notification (Fixed in v1.4.0)

**Problem**: When SendKeys injection fails, you wouldn't know about it.

**Solution**: Failed injections now send a notification to Telegram, so you know when to check manually.

### ✅ Permission Prompts (Solved with Hooks)

**Problem**: Cannot approve sensitive operations remotely.

**Solution**: Use the included PreToolUse hooks for remote approval via Telegram. See [Remote Permission Approval](#remote-permission-approval-recommended) section.

### ⚠️ SendKeys Reliability (Windows)

The terminal injection feature uses `WriteConsoleInput` API for no-focus injection:

**How it works:**
- Uses Windows Console API to write directly to the console input buffer
- Does not require window focus
- Does not use clipboard
- Works when other applications are active

**Limitation - Single Terminal Only:**
- Works correctly when only one terminal window is open
- If multiple terminals are open, messages may go to the wrong terminal
- This is due to Windows Terminal's ConPTY architecture

**When it may fail**:
- Multiple terminal windows open simultaneously
- Remote desktop or virtual machine environments
- Screen is locked

**Workaround**: Use hooks instead of SendKeys for more reliable operation, or ensure only one terminal is open.

### ⚠️ Platform Support

| Platform | MCP Tools | Auto-Injection | Hooks |
|----------|-----------|----------------|-------|
| Windows | ✅ Full | ✅ SendKeys | ✅ Full |
| macOS | ✅ Full | ❌ Not implemented | ✅ Full |
| Linux | ✅ Full | ❌ Not implemented | ✅ Full |

**Recommendation**: Use hooks for cross-platform remote control.
