169/169 Bot API methods with Zod validation, token masking, tool annotations, and zero bloat (2 dependencies).

Features

• 169/169 Bot API methods — messages, media, polls, chats, forums, stickers, payments, business, stories, gifts, games, inline, managed bots
• Bot API 9.6 (April 2026) — managed bots, revoting polls, shuffle options, poll descriptions
• Meta-mode — 2 tools instead of 169, saves ~99% context tokens
• Rate limiting — global (30 req/sec) + per-chat (20 msg/min), token bucket with async mutex
• Circuit breaker — 3-state (closed/open/half-open), auto-recovery
• Retry with backoff — respects Telegram 429 retry_after, exponential backoff on 5xx
• Zod validation — every parameter validated before hitting Telegram API
• Token masking — bot token never appears in responses, logs, or error messages
• File upload security — path traversal protection, configurable allowed directories
• Tool annotations — all 169 methods annotated (readOnly, destructive, idempotent, openWorld)
• Response truncation — 100K char limit to prevent context overflow
• Zero bloat — only 2 dependencies: @modelcontextprotocol/sdk + zod

Quick Start

Claude Code

claude mcp add telegram -- npx telegram-api-mcp -e TELEGRAM_BOT_TOKEN=your_token

With meta-mode (recommended for large conversations):

claude mcp add telegram -- npx telegram-api-mcp \
  -e TELEGRAM_BOT_TOKEN=your_token \
  -e TELEGRAM_META_MODE=true

Claude Desktop

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "telegram": {
      "command": "npx",
      "args": ["telegram-api-mcp"],
      "env": {
        "TELEGRAM_BOT_TOKEN": "your_token_from_botfather"
      }
    }
  }
}

With default chat (skip chat_id in every call)

{
  "mcpServers": {
    "telegram": {
      "command": "npx",
      "args": ["telegram-api-mcp"],
      "env": {
        "TELEGRAM_BOT_TOKEN": "your_token",
        "TELEGRAM_DEFAULT_CHAT_ID": "-1001234567890"
      }
    }
  }
}

From source

git clone https://github.com/timoncool/telegram-api-mcp.git
cd telegram-api-mcp
npm install && npm run build
TELEGRAM_BOT_TOKEN=your_token node dist/index.js

Environment Variables

Variable	Required	Default	Description
TELEGRAM_BOT_TOKEN	Yes	—	Bot token from @BotFather
TELEGRAM_DEFAULT_CHAT_ID	No	—	Default chat ID for all tools
TELEGRAM_DEFAULT_THREAD_ID	No	—	Default forum topic thread ID
TELEGRAM_META_MODE	No	false	Use 2 meta-tools instead of 169
TELEGRAM_GLOBAL_RATE_LIMIT	No	30	Max requests/sec (Telegram limit)
TELEGRAM_PER_CHAT_RATE_LIMIT	No	20	Max messages/min per group (Telegram limit)
TELEGRAM_MAX_RETRIES	No	3	Retry attempts on transient errors
TELEGRAM_CB_THRESHOLD	No	5	Failures before circuit opens
TELEGRAM_CB_COOLDOWN	No	30000	Circuit breaker cooldown (ms)
TELEGRAM_ALLOWED_UPLOAD_DIRS	No	—	Comma-separated allowed upload paths
TELEGRAM_MAX_FILE_SIZE	No	52428800	Max upload file size (50MB)

Meta Mode

When TELEGRAM_META_MODE=true, the server exposes only 2 tools instead of 169:

• telegram_find — search methods by keyword or category
• telegram_call — call any method by name with JSON params

This saves ~99% of context tokens while keeping full API access:

User: "Post a poll in my channel"
AI: → telegram_find(query: "poll")
AI: → telegram_call(method: "sendPoll", params: { chat_id: ..., question: "...", options: [...] })

Design principles

• Declarative registry — each method is pure data (name, params, types, annotations). One generic handler serves all 169 methods. Adding a new method = one array entry.
• Zod validation — every parameter validated before reaching Telegram. Clear error messages with hints instead of opaque API 400s.
• Token bucket rate limiting — no race conditions (async mutex). Defaults match Telegram's official limits: 30 req/sec global, 20 msg/min per group.
• Circuit breaker — 429 (rate limit) is NOT counted as failure. Only real errors (5xx, network) trip the breaker. Half-open probe recovers automatically.
• Tool annotations — every method has MCP annotations (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) so AI clients know which tools are safe to auto-approve.
• Response truncation — responses capped at 100K chars to prevent context window overflow.

Security

• Bot token never appears in MCP tool responses or error messages (masked as ***)
• File upload paths validated against allowed directories (TELEGRAM_ALLOWED_UPLOAD_DIRS)
• Path traversal attacks blocked (resolve + normalize + separator check)
• No eval(), no Function(), no dynamic imports
• No external requests except api.telegram.org
• No telemetry, no analytics, no phone-home
• Zero bloat: only 2 runtime dependencies (@modelcontextprotocol/sdk + zod)
