Tools

• get_me - Get bot identity.

• send_message - Send a text message to a chat.

• send_photo - Send a photo by URL or file ID.

Safety Notes

send_message, send_photo, answer_callback_query, and edit_message_text are user-visible. They can contact real Telegram users or groups and may trigger notifications. Confirm chat_id, message_id, callback IDs, and message contents before calling write tools.

Telegram bot tokens grant control of the bot. Do not commit tokens or chat exports.

Important DAuth Limitation

Telegram's official Bot API requires the token in the request URL:

https://api.telegram.org/bot<TOKEN>/<method>

dedalus_mcp 0.7.0 Connection supports secret injection into HTTP headers, not URL path templating. This repository still declares a DAuth connection named telegram-mcp with secret key TELEGRAM_BOT_TOKEN, but the implemented HTTP calls use a server-side TELEGRAM_BOT_TOKEN environment variable until path-secret support is available.

This means the current code is best deployed as a Type 2/3 server with a server or required credential environment value, not as a fully isolated path-templated DAuth server. Revisit this once Dedalus supports path credential templating for Telegram.

Environment

TELEGRAM_BOT_TOKEN=123456:ABC-DEF...
DEDALUS_AS_URL=https://as.dedaluslabs.ai

For _client.py:

DEDALUS_API_KEY=dsk-live-...
DEDALUS_API_URL=https://api.dedaluslabs.ai
DEDALUS_MCP_SERVER=dedalus-labs/telegram-mcp
TELEGRAM_TEST_CHAT_ID=...
TELEGRAM_TEST_MESSAGE_ID=...
TELEGRAM_TEST_CALLBACK_QUERY_ID=...

Run Locally

uv run python src/main.py

In another terminal:

MCP_SERVER_URL=http://127.0.0.1:8080/mcp uv run python src/_client.py

The client calls every tool. It intentionally includes write calls, so use a safe test chat.

Deploy

Publish as dedalus-labs/telegram-mcp, configure TELEGRAM_BOT_TOKEN securely, deploy, then run:

DEDALUS_MCP_SERVER_ONLY=1 DEDALUS_MCP_SERVER=dedalus-labs/telegram-mcp uv run python src/_client.py
