Claude Channels Telegram

The missing outbound layer for Claude Channels. Adds photos, files (PDFs, source code), keyboards, Telegram Stars, and TON tools to Claude Code — safely coexisting with Channels via CHANNELS_MODE (no polling conflicts).

What This Is

Claude Channels handles inbound Telegram messages and provides reply, react, and edit_message for outbound. That's it. Any richer response — a photo, a file, a button, a payment invoice — requires this toolkit.

Example: Claude Code coding session, results delivered to Telegram

Claude does	Tool
Generates a chart or graph	send_photo → image in Telegram
Edits a source file	send_document → file delivered to Telegram
Produces a test result report (PDF)	send_document → PDF in Telegram
Takes a screenshot during web testing	send_photo → screenshot in Telegram

Claude Channels built-in	This toolkit adds
reply — plain text response	send_keyboard — inline buttons (URL or callback)
react — emoji reaction	send_photo, send_document — media
edit_message — edit sent message	send_invoice — Telegram Stars payment
(inbound handled automatically)	register_commands, set_bot_description — BotFather setup
—	16 TON blockchain tools incl. TON Connect

Why not just use any Bot API MCP?

Other Bot API MCP servers (TONresistor/telegram-mcp, tsgram-mcp, ton-agent-kit) also provide outbound tools — but they all poll getUpdates continuously. Running them alongside Claude Channels causes offset conflicts: messages get dropped or delivered twice.

CHANNELS_MODE=true disables all polling in this toolkit. Channels owns the inbound; this toolkit handles the outbound. No conflicts.

Primary mode: CHANNELS_MODE

CHANNELS_MODE (CHANNELS_MODE=true) — the intended use case, alongside Claude Channels:

• Inbound: handled by Channels automatically
• Outbound: all 30 send/TON tools available
• Polling disabled — no offset conflicts with Channels

Standalone (no Channels) — also supported, without the Channels plugin:

• Inbound: get_updates / get_pending_messages available
• All 33 tools available

MCP Tools — 30 in CHANNELS_MODE / 33 standalone

Quick Start

git clone https://github.com/Masashi-Ono0611/claude-channels-telegram-mcp.git
cd claude-channels-telegram-mcp && bun install

Configure MCP

Add to your project's .mcp.json:

{
  "mcpServers": {
    "telegram-toolkit": {
      "command": "bun",
      "args": ["run", "/path/to/claude-channels-telegram-mcp/src/index.ts"],
      "env": {
        "TELEGRAM_BOT_TOKEN": "<your-bot-token>",
        "TON_API_BASE_URL": "https://testnet.tonapi.io",
        "CHANNELS_MODE": "true"
      }
    }
  }
}

Operating Modes

Mode	When to use	Tools
CHANNELS_MODE (recommended)	With Claude Channels plugin	30 tools (polling excluded)
Standalone	Without Claude Channels	33 tools (polling included)

Set CHANNELS_MODE=true in your .mcp.json env (shown above — already included in the example).

Environment Variables

# Required
TELEGRAM_BOT_TOKEN=<bot-token-from-botfather>
CHANNELS_MODE=true   # set to true when using alongside Claude Channels plugin

# TON network (auto-detects testnet/mainnet from URL)
TON_API_BASE_URL=https://testnet.tonapi.io    # testnet (default)
TON_API_BASE_URL=https://tonapi.io            # mainnet
TON_API_KEY=<optional-api-key>               # increases rate limits

# Agent wallet (required for send_ton / transfer_jetton)
AGENT_MNEMONIC_PATH=/path/to/mnemonic.txt
TONCENTER_ENDPOINT=<override-if-needed>      # auto-derived from TON_API_BASE_URL
TONCENTER_API_KEY=<optional-toncenter-key>

If TON env vars are not set, TON tools return "not configured" errors. Telegram tools work regardless.

Architecture

Claude Code
  │
  ├── Claude Channels (built-in plugin)
  │   └── reply, react, edit_message (inbound + outbound messaging)
  │
  └── claude-channels-telegram-mcp (this MCP server)
      ├── Telegram: send, keyboards, media, commands, invoice, callbacks, polling
      └── TON: balance, price, swap, transfer, payment links, tx history, jetton, wallet connect

Key design: In CHANNELS_MODE, only send-only APIs are active — no polling conflicts with Channels. In standalone mode, get_updates + send_message + answer_callback_query provide a full receive-respond loop. TON read tools use tonapi.io; write tools use TonCenter RPC. Network (testnet/mainnet) is auto-detected from TON_API_BASE_URL.

Complete Response Pipeline (standalone)

User presses inline button → get_updates → callback_query received
→ answer_callback_query("Processing...") → send_invoice(Stars)
→ User pays → pre_checkout_query received
→ answer_pre_checkout_query(ok=true) → send_message("Payment complete!")

Payment Link Flow (CHANNELS_MODE or standalone)

generate_ton_payment_link + send_keyboard enables a user-pays flow without exposing the agent wallet:

Claude → generate_ton_payment_link → send_keyboard with URL button
User taps button → TonKeeper / any TON wallet opens → user signs & sends
Claude → get_transactions → verify payment received

TON Connect Flow (user wallet)

generate_tonconnect_link + send_keyboard connects a user's own wallet (TonKeeper) without exposing any agent private key:

Claude → generate_tonconnect_link → { session_id, tonkeeper_link }
Claude → send_keyboard with URL button (tonkeeper_link)
User taps → TonKeeper opens → user approves connection
Claude → check_tonconnect_session(session_id) → { status: "connected", address }
Claude → request_ton_payment(session_id, to, "0.5") → user approves in TonKeeper → { boc }
Claude → disconnect_wallet(session_id)

Session state is persisted to ~/.ctt/sessions/<session_id>.json, so connection survives across MCP calls.

CHANNELS_MODE: What Works and What Doesn't

In CHANNELS_MODE (CHANNELS_MODE=true), the three polling tools are disabled at both ListTools and CallTool level to prevent offset conflicts with the Channels plugin.

⚠️ reply vs send_message — not interchangeable

	Channels reply	toolkit send_message
Responds in conversation thread	✅	❌ (sends a new standalone message)
Requires chat_id	❌ (implicit)	✅ (must provide)
Available in CHANNELS_MODE	✅	✅

Use Channels reply for all conversational responses. Use send_message only for proactive or scheduled sends (e.g. notifications).

⚠️ Callback buttons don't work in CHANNELS_MODE

Callback buttons (callback_data) require get_updates to receive the callback event back from Telegram. Since polling is disabled in CHANNELS_MODE, the callback data is never delivered to Claude.

Button type	CHANNELS_MODE	Standalone
URL button (url field) — opens a link	✅ works	✅ works
Callback button (callback_data) — returns data to bot	❌ data never arrives	✅ works

In CHANNELS_MODE, use URL buttons for all interactive elements (payment links, TonKeeper connect, external pages).
