Features

Feature	Description
:building_construction: Dual Transport	Stdio for local MCP clients, HTTP for remote deploys (`http-auth` production, optional `http-no-auth` for dev)
:closed_lock_with_key: Multi-User Authentication	Shared `http-auth` server: one Bearer token per user, one Telegram account per MCP connection; session isolation and LRU cache
:dart: AI-Optimized	8 consolidated tools vs 80+ micro-tools — context-efficient design, LLM-friendly API, MCP ToolAnnotations
:globe_with_meridians: HTTP-MTProto Bridge	Direct curl access to any Telegram API method with entity resolution and safety guardrails
:shield: Session ACL	Opt-in per-principal limits on `http-auth` (`ACL_ENABLED`) — chat lanes, `read_only`, `blocked_peers`, `allow_mtproto`, `ACL_DENY_UNLISTED_PRINCIPALS`; see SECURITY.md
:tv: Web Setup Interface	Browser-based authentication flow with immediate config generation
:label: One Agent, Multiple Accounts	Optional `PREFIX_MCP_TOOLS_WITH_ACCOUNT` — when one agent uses several MCP connections (same server, different tokens), prefixes tool names so they do not collide; not needed for standard multi-user hosting
:rocket: MTProto Proxy Support	Connect via MTProto proxy with automatic Fake TLS (EE prefix) and standard proxy detection
:card_file_box: Unified Session Management	Single configuration system for setup and server; per-token session files on shared multi-user hosts
:mag_right: Intelligent Search	Global & per-chat message search with multi-query support and intelligent deduplication
:mag: Unified Message API	Single `get_messages` tool for search, browse, read by IDs, and replies - 5 modes in one
:speech_balloon: Universal Replies	Get replies from channel posts, forum topics, or any message with one parameter
:busts_in_silhouette: Smart Contact Discovery	Search users, groups, channels with uniform entity schemas, forum detection, profile enrichment
:file_folder: Folder Filtering	Filter chats by dialog folder (archived, custom folders) with integer ID or name matching
:envelope: Advanced Messaging	Send, edit, reply, post to forum topics, formatting, file attachments, and phone number messaging
:paperclip: Secure File Handling	Rich media sharing with SSRF protection, size limits, album support, optional HTTP attachment streaming
:outbox_tray: Inline File Uploads	Data: URI (base64) file uploads in `files` param — work in all transport modes, filenames preserved, images sent as photos
:microphone: Voice Transcription	Automatic speech-to-text for Premium accounts with parallel processing and polling
:zap: High Performance	Async operations, parallel queries, and memory-conscious batching
:shield: Production Reliability	Auto-reconnect, configurable logging, comprehensive error handling

Quick Start

1. Install and authenticate

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

Sessions are stored in ~/.config/fast-mcp-telegram/.

Bot token alternative: Set BOT_API_TOKEN instead of --phone-number to skip OTP. See Installation Guide.

2. Configure MCP Client

stdio mode (local):

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

http-auth mode (remote): See Installation Guide for deploying your own server and authenticating via web interface.

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.
