Why This Exists

After trying email, SMS, and Google Chat integrations, Telegram emerged as the best solution for:

• ✅ Standardized MCP Integration - Works with any Claude instance automatically
• ✅ Instant two-way communication
• ✅ Free and reliable
• ✅ Works on all devices
• ✅ Simple setup
• ✅ No carrier dependencies

Features

• 💬 Two-Way Communication - Send messages to Claude, get responses back
• ❓ Question/Answer Flow - Claude can ask you questions and wait for answers
• 📬 Message Queue - Messages queue up when Claude is busy, get answered ASAP
• 🔔 Priority Notifications - Different icons for info, success, warning, error, question
• 🌐 HTTP API - Easy integration from any app/project
• 🚀 Background Service - Runs independently, always available
• 🔧 MCP Protocol - Works as a standard MCP server in any Claude project

How It Works

This is a standard MCP server that works like any other MCP tool. Once installed and configured:

1. Bridge runs as a background service (connects to Telegram)
2. MCP server is auto-started by Claude when needed
3. Claude discovers 5 tools automatically
4. You communicate via Telegram in real-time

Quick Start

1. Create Your Telegram Bot

1. Open Telegram and search for @BotFather
2. Send /newbot
3. Follow the prompts:
   • Choose a name for your bot (e.g., "My Claude Bridge")
   • Choose a username (e.g., "my_claude_bridge_bot")
4. Save your bot token - BotFather will give you a token like:

   1234567890:ABCdefGHIjklMNOpqrsTUVwxyz
   

5. Find your bot in Telegram using the username you created

2. Install and Configure

# Clone or download this repo
cd innervoice

# Install dependencies
pnpm install

# The .env file is created automatically!
# Just edit it and add your bot token
# TELEGRAM_BOT_TOKEN=your_token_here

Edit .env:

TELEGRAM_BOT_TOKEN=1234567890:ABCdefGHIjklMNOpqrsTUVwxyz
TELEGRAM_CHAT_ID=  # Leave empty - auto-set on first use
PORT=3456
HOST=localhost
ENABLED=true

3. Build and Start

# Build the project
pnpm build

# Start the bridge service
pnpm dev

# Or run as background daemon
pnpm daemon

4. Initialize Your Bot

1. Open Telegram and find your bot
2. Send /start to your bot
3. The bot will reply and save your chat ID automatically
4. Test with /status to verify it's working

5. Add MCP Server to Claude

✨ Auto-Start Feature: The MCP server now automatically starts the Telegram bridge when needed - no need to run it separately!

Option A: Claude Code CLI (Recommended)

Note: Using claude mcp add automatically adds the server globally (available in all projects). This is the recommended approach.

For Mac and Linux:

# Navigate to the innervoice directory
cd /path/to/innervoice

# Add the MCP server globally (available in all projects)
claude mcp add --transport stdio telegram \
  --env TELEGRAM_BRIDGE_URL=http://localhost:3456 \
  -- node "$(pwd)/dist/mcp-server.js"

# Verify it was added globally
claude mcp list

For Windows (PowerShell):

# Navigate to the innervoice directory
cd C:\path\to\innervoice

# Add the MCP server globally
claude mcp add --transport stdio telegram `
  --env TELEGRAM_BRIDGE_URL=http://localhost:3456 `
  -- node "$((Get-Location).Path)\dist\mcp-server.js"

# Verify it was added
claude mcp list

For Windows (Command Prompt):

# Navigate to the innervoice directory
cd C:\path\to\innervoice

# Add the MCP server globally
claude mcp add --transport stdio telegram --env TELEGRAM_BRIDGE_URL=http://localhost:3456 -- node "%CD%\dist\mcp-server.js"

# Verify it was added
claude mcp list

Option B: Manual Config File Setup

Add to your Claude Code MCP settings:

Mac/Linux: ~/.claude.json Windows: %USERPROFILE%\.claude.json

{
  "mcpServers": {
    "telegram": {
      "command": "node",
      "args": [
        "/ABSOLUTE/PATH/TO/innervoice/dist/mcp-server.js"
      ],
      "env": {
        "TELEGRAM_BRIDGE_URL": "http://localhost:3456"
      }
    }
  }
}

Find your absolute path:

Mac/Linux:

cd innervoice && pwd
# Use output: <result>/dist/mcp-server.js

Windows (PowerShell):

cd innervoice
(Get-Location).Path
# Use output: <result>\dist\mcp-server.js

Windows (Command Prompt):

cd innervoice
cd
# Use output: <result>\dist\mcp-server.js

6. Available Tools

Once configured, Claude can automatically use:

• telegram_notify - Send notifications
• telegram_ask - Ask questions and wait for answers
• telegram_get_messages - Check for messages from you
• telegram_reply - Reply to your messages
• telegram_check_health - Check bridge status
• telegram_toggle_afk - Toggle AFK mode (enable/disable notifications)

View detailed tool info:

pnpm tools
# or
node scripts/list-tools.js

7. AFK Mode - Control Your Notifications

Use the /afk slash command to toggle notifications on/off:

# In Claude Code, just type:
/afk

This is perfect for:

• Enabling when you step away from your computer (get notified via Telegram)
• Disabling when you're actively working (no interruptions)

The toggle state is preserved while the bridge is running, and you'll get a Telegram message confirming each change.

8. Verify Global Setup

After adding the MCP server, verify it's available globally:

# Check that telegram appears in the list
claude mcp list

# Should show:
# ✓ telegram: Connected

Troubleshooting: If telegram only appears in one project but not others, it was added to a project-specific config instead of globally. To fix:

1. Open ~/.claude.json in your editor
2. Find the telegram server config under projects → your-project-path → mcpServers
3. Move it to the root-level mcpServers section (same level as other global servers)
4. Remove the telegram entry from the project-specific section

Example structure:

{
  "mcpServers": {
    "telegram": {
      "type": "stdio",
      "command": "node",
      "args": ["/path/to/innervoice/dist/mcp-server.js"],
      "env": {"TELEGRAM_BRIDGE_URL": "http://localhost:3456"}
    }
  },
  "projects": {
    "/your/project/path": {
      "mcpServers": {}  // Should be empty or not contain telegram
    }
  }
}

9. Test It

Restart Claude Code, then tell Claude:

"Send me a test notification via Telegram"

Claude will automatically discover and use the telegram_notify tool!

MCP Tools Reference

Git Setup (For Sharing)

If you want to push this to your own Git repository:

# Initialize git (if not already done)
git init

# Add all files (gitignore protects secrets)
git add .

# Commit
git commit -m "Initial commit: Telegram MCP server"

# Add your remote
git remote add origin https://github.com/yourusername/innervoice.git

# Push
git push -u origin main

What's Safe to Share:

• ✅ All source code
• ✅ .env.example (template)
• ✅ Documentation
• ✅ Configuration templates

What's Protected (in .gitignore):

• 🔒 .env (your bot token and secrets)
• 🔒 node_modules/
• 🔒 dist/

For Others Cloning Your Repository

When someone clones your repo, they need to:

1. Create their own Telegram bot with @BotFather
2. Copy the template: cp .env.example .env
3. Add their bot token to .env
4. Install and build: pnpm install && pnpm build
5. Follow the Quick Start guide above

Legacy HTTP API (For Direct Integration)

If you want to use the HTTP API directly (without MCP), you can:

// Simple notification
await fetch('http://localhost:3456/notify', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({
    message: 'Scraping complete! Found 500 skills.',
    priority: 'success'
  })
});

// Question with markdown
await fetch('http://localhost:3456/notify', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({
    message: '*Question:*\nContinue scraping sets?\n\nReply: yes/no',
    priority: 'question',
    parseMode: 'Markdown'
  })
});

Priority Levels

• info - ℹ️ General information
• success - ✅ Task completed
• warning - ⚠️ Warning message
• error - ❌ Error occurred
• question - ❓ Needs your input

Bot Commands

Type these in Telegram to control the bridge:

• /start - Initialize connection and save your chat ID
• /help - Show all available commands and how to use the bridge
• /status - Check bridge status (enabled, unread messages, pending questions)
• /test - Send a test notification to verify it's working

How Two-Way Communication Works

You → Claude

1. Send any message to the bot in Telegram
2. Bot acknowledges with "💬 Message received - responding..."
3. Claude checks messages and responds when available
4. You get the response in Telegram

Claude → You (Notifications)

Claude sends you updates via the /notify API endpoint with different priorities

Claude → You (Questions)

1. Claude sends a question via /ask API
2. You see "❓ [question]" in Telegram
3. Your next message is automatically treated as the answer
4. Claude receives your answer and continues
