✨ Key Features

• 🔑 Instant Session Switching (tg-cli auth <path.session>): Pass any existing Telethon .session file directly. Automatically validates SQLite integrity, detects the target server cluster, and aligns settings.
• 🤖 Bot Testing & Automation: Send text payloads, trigger slash commands (e.g. /start), inspect responses, and click inline keyboard buttons.
• 🛡️ Environment Mismatch Shield: Automatically detects whether your session belongs to the Test Server (Sandbox) or Production Server and protects against cross-environment auth revocation.
• 🔒 Process-Level Session Guard: Prevents concurrent duplicate connections (/tmp/telegram-mcp.lock) to eliminate AuthKeyDuplicatedError.
• 📁 Rich Terminal Display: Colorized output, message panels, button trees, and clean tabular diagnostics powered by rich.
• ⚡ Arbitrary MTProto Execution (tg-cli exec): Direct command-line evaluation of Python MTProto snippets with live client injection.

🚀 Quick Start

1. Installation

From PyPI (Recommended):

pip install telegram-mcp-cli

From Source:

git clone https://github.com/Telegram-mcp/telegram-mcp-cli.git
cd telegram-mcp-cli
pip install -e .

2. Configure Authentication

To set up or switch active sessions directly:

# Option A: Point to an existing Telethon .session file
tg-cli auth /path/to/my_account.session

# Option B: Run interactive phone / QR login
tg-cli auth login

3. Verify Connection

tg-cli status

💻 Command Reference

🛡️ Safety & Session Protection

• File Locking: tg-cli uses /tmp/telegram-mcp.lock to ensure no two processes use the session concurrently.
• Environment Matching: Test Server sessions (DC 2 Sandbox) and Production sessions cannot be cross-connected. The CLI will abort with a clear warning before Telegram revokes the key.

🧪 Testing

Run the automated unit test suite with pytest:

python3 -m pytest tests -v
