fast-mcp-telegram

Telegram MCP Server — Model Context Protocol (MCP) gateway for Telegram. 8 context-efficient tools, multi-tenant, MTProto bridge.

Canonical GitHub repository: alexeyleshchenko/fast-mcp-telegram. This is the same project previously published under leshchenko1979/fast-mcp-telegram. The old GitHub URL is a public 404. Install remains pip install fast-mcp-telegram or uvx --from fast-mcp-telegram; PyPI is the stable pointer.

Try the Demo

1. Open https://tg-mcp.l1979.ru/setup
2. Scan the QR code from Telegram mobile (Settings → Devices → Scan QR) — no phone typing, no OTP, no 2FA. Or enter your phone number as fallback.
3. Copy your Bearer token from the success page

Then choose your path:

MCP Client (AI assistants)

• From the setup page, download the mcp.json file
• Add the server to your AI client and ask: "send hello to my saved messages in telegram"

Direct API (curl)

• Run the command below (replace TOKEN with yours):

curl -X POST "https://tg-mcp.l1979.ru/mtproto-api/messages.SendMessage" \
  -H "Authorization: Bearer TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"params": {"peer": "me", "message": "Hello!"}}'

How It Works

This server sits between your AI agent and Telegram's API:

Your agent → MCP/HTTP → this server → MTProto → Telegram

What it does: Authenticates you with Telegram (QR or phone/bot token), exposes 8 AI-friendly tools instead of 80+ micro-APIs, and bridges raw MTProto for power users. Multi-tenant — one server, many users, isolated sessions.

Features

Prerequisite: Install uv — see docs if you don't have it. Or use Docker (see Installation Guide).

Quick Start

1. Install and authenticate

Quickest path (remote server): Open /setup → scan QR → copy token (see Try the Demo).

CLI path (local stdio): Run fast-mcp-telegram-setup once to create a Telegram session — then fast-mcp-telegram serves it:

uvx --from fast-mcp-telegram fast-mcp-telegram-setup \
  --api-id="your_api_id" \
  --api-hash="your_api_hash" \
  --phone-number="+123456789"

Bot token alternative (no phone, no OTP): Set BOT_API_TOKEN instead of --phone-number. See Installation Guide.

2. Configure MCP Client

stdio mode (local): Add to your MCP client config (e.g. claude_desktop_config.json) — stdio (standard input/output) is the default transport for local MCP clients:

{
  "mcpServers": {
    "telegram": {
      "command": "uvx",
      "args": ["fast-mcp-telegram"],
      "env": {
        "API_ID": "your_api_id",
        "API_HASH": "your_api_hash"
      }
    }
  }
}

http-auth mode (remote): Add to your MCP client config (e.g. claude_desktop_config.json):

{
  "mcpServers": {
    "telegram": {
      "url": "https://tg-mcp.l1979.ru/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_TOKEN"
      }
    }
  }
}

Get your token by scanning the QR code on the setup page or see Installation Guide for deploying your own server.

3. Start Using

{"tool": "search_messages_globally", "params": {"query": "hello", "limit": 5}}
{"tool": "get_messages", "params": {"chat_id": "me", "limit": 10}}
{"tool": "send_message", "params": {"chat_id": "me", "message": "Hello!"}}

Deploy to Remote Server

Deploy your own MCP server on a VDS — see Installation Guide for step-by-step instructions.

Telemetry

Anonymous tool telemetry since v0.30.1 — heartbeat every 6h, no credentials or message content collected. Opt out with DO_NOT_TRACK=1. See ADR 0005.

Auth flow telemetry since v0.38.0 — atomic events during setup (phone, QR, bot token, reauthorize). Buffered flush on flow completion. See ADR 0008.
