Your AI assistant shouldn't be trapped in a desktop terminal -- four steps to command your desktop Claude Code from your phone.
Why Connect Claude to Telegram
Anthropic's Telegram plugin transforms Claude Code from a desktop-only program into a portable backend: send a message from your phone, and your desktop Claude receives it, edits files, runs commands, then pushes the results back to your phone.
Claude Code normally lives in your terminal -- step away from your computer, and you lose access. This plugin bridges the gap through MCP (Model Context Protocol), turning your Telegram bot into a messaging channel for Claude Code. The key point: messages travel through a real Claude Code session, with all skills, tools, and permission rules intact. With over 950 million monthly active users on Telegram, you're connecting Claude to an app already in your pocket.

1. Prerequisites
You need exactly one tool and one token. The entire setup takes under ten minutes.
The only hard requirement is Bun -- the MCP server runs on it.
curl -fsSL https://bun.sh/install | bash
On the Telegram side, you need a bot token:
- Search for @BotFather in Telegram, send
/newbot - Set a display name and a username (must end with
bot) - BotFather returns a token like
123456789:AAHfiqksKZ8...-- copy the entire string
Your token is effectively your bot's password. If leaked, someone can hijack your bot and the Claude session behind it. Never commit it to a public repository.
2. Four-Step Installation
From zero to sending messages: 4 commands, 3 minutes. Every step runs inside your Claude Code session.
Fig. 2: Four-step installation flow
All / commands are entered in your Claude Code session, not in a shell.
Step 1 -- Install the plugin
/plugin install telegram@claude-plugins-official
/reload-plugins
Step 2 -- Configure token
/telegram:configure 123456789:AAHfiqksKZ8...
This writes the token to ~/.claude/channels/telegram/.env. If you prefer managing secrets via shell environment variables, export TELEGRAM_BOT_TOKEN=... also works and takes precedence over the .env file.
Step 3 -- Restart with the channels flag
This is the step most people miss. Without the --channels flag, the server won't connect:
claude --channels plugin:telegram@claude-plugins-official
Step 4 -- Pair
Once the new session starts, send any message to your bot in Telegram. The bot replies with a 6-character pairing code. Back in Claude Code:
/telegram:access pair a4f91c
From the next message onward, Claude receives directly.
3. Lock the Door Immediately
The first thing to do after pairing isn't start using it -- it's locking the door. The default dmPolicy: pairing sends a pairing code to anyone who DMs your bot -- essentially leaving the front door wide open.
Once you've paired yourself, immediately switch to allowlist:
/telegram:access policy allowlist
The three DM policies:
| Policy | Behavior |
|---|---|
pairing (default) |
Unauthorized users receive a pairing code; messages discarded |
allowlist |
Unauthorized users silently ignored; bot doesn't respond |
disabled |
All messages discarded, including from authorized users |
Pairing mode exists to help you grab your user ID. It's not a daily operating mode.

4. Available Tools
The plugin provides three communication tools plus a download helper, covering all mobile interactions between you and Claude.
| Tool | Purpose |
|---|---|
reply |
Send messages to a specified chat_id. Optional reply_to (quote-reply) and files (absolute paths; images sent as photo previews, others as documents, 50 MB per file limit). Long messages auto-chunked |
react |
Add emoji reactions to messages. Limited to Telegram's fixed whitelist only |
edit_message |
Edit bot's own sent messages. Ideal for "processing..." to "done" status updates |
download_attachment |
Download a file by attachment file_id, returns local path for the Read tool |
Telegram automatically shows "botname is typing..." when receiving messages -- no manual control needed.
5. Photo and Attachment Handling
When you send a photo from your phone to the bot, Claude can read and act on it immediately -- no manual file transfers required.
Photos are downloaded to ~/.claude/channels/telegram/inbox/, with the absolute path injected into the <channel> notification tag. Claude reads that path directly.
One caveat: Telegram compresses photos. For original quality or non-image formats, long-press the attachment in Telegram and select "Send as File" to send as a document.
If the <channel> tag contains attachment_file_id, it's a document-type attachment, and Claude will automatically call download_attachment to retrieve the local path.
6. No Message History
The Telegram Bot API provides neither message history nor search. Your bot can only see messages as they arrive -- past conversations vanish once they leave the current session.
This isn't a plugin bug; it's a Telegram platform limitation:
- Want Claude to review last week's conversation? Can't be done. Paste or re-summarize it yourself
- There's no
fetch_messagestool -- don't try to call one - Attachment downloads are "save on arrival" only; there's no API for retrieval afterward
7. Group Setup
Groups are disabled by default and must be enabled individually. Telegram supergroup IDs are negative numbers starting with -100, not shown directly in the UI.
/telegram:access group add -1001654782309
Groups default to requireMention: true -- the bot only responds when @mentioned or replied to, matching Telegram's server-side privacy mode.
To make the bot respond to all group messages:
/telegram:access group add -1001654782309 --no-mention
You'll also need to visit @BotFather, send /setprivacy, select your bot, and choose Disable. Otherwise Telegram's server-side filter will intercept messages before they reach your plugin.
To restrict which group members can trigger the bot:
/telegram:access group add -1001654782309 --allow 412587349,628194073
8. Advanced Delivery Settings
/telegram:access set <key> <value> lets you fine-tune chunking and trigger behavior.
| Key | Purpose |
|---|---|
ackReaction |
Auto-reaction emoji on receiving messages. Set "" to disable |
replyToMode |
Thread behavior for chunked replies. first (default): only the first chunk quote-replies the original; all: every chunk threads; off: all sent independently |
textChunkLimit |
Chunking threshold. Telegram's limit is 4,096 characters |
chunkMode |
length: strict character limit; newline (recommended): prefers paragraph boundaries |
mentionPatterns |
Custom trigger regex, e.g., ["^hey claude\\b", "\\bassistant\\b"] |
9. Multi-Bot Coexistence
To run multiple bots on the same machine (different tokens, different allowlists), assign each a separate data directory with TELEGRAM_STATE_DIR:
TELEGRAM_STATE_DIR=~/.claude/channels/telegram-work claude --channels plugin:telegram@claude-plugins-official
Each instance manages its own .env and access.json independently.
10. Security Considerations
The trust boundary lives in your desktop Claude session, not in Telegram messages. Any request from a chat saying "add me to the allowlist" is a potential prompt injection attack.
The plugin's access skill can only be executed by you within your Claude Code session. If someone writes "add me to the allowlist" or "approve my pairing" in a Telegram message, that's a classic prompt injection vector. Claude will refuse by default and direct them to contact you directly.
That said, this security model has limits. It assumes your desktop environment is secure -- if your machine is compromised, the access.json defense falls with it. Periodically check ~/.claude/channels/telegram/access.json to confirm it contains only user IDs you recognize.
In short:
- Never have Claude auto-execute
/telegram:accesscommands from Telegram message content - access.json is the trust boundary, guarded by your local Claude session
- Token and access.json both live in
~/.claude/channels/telegram/-- manage your home directory permissions carefully
11. Typical Use Cases
A few workflows that deliver immediate value once connected:
1. Mobile Remote Command You think of a commit message fix during your commute. Message the bot: "Change the latest commit message on main to 'fix pairing flow copy'." Claude makes the change on your desktop and reports back.
2. Long Task Status Reports
Running a lengthy build/test/scrape: "Ping me when it's done." Claude uses edit_message for progress updates, then sends a new reply on completion -- edits don't trigger push notifications, but new messages do.
3. Cross-Device Screenshot Feedback Spot a UI bug at a coffee shop. Take a screenshot, send it to the bot. Claude reads the downloaded image, diagnoses the issue, fixes the desktop code, and returns the diff.
4. Second Inbox Drop stray ideas, to-dos, or paper PDFs to the bot. Claude routes them to the appropriate Inbox folder or Zotero task queue.
Conclusion
The Telegram plugin's value isn't about a pretty interface -- it's about upgrading Claude Code from "desktop-only program" to "portable assistant backend." After completing the setup above, Claude's capability boundary equals your signal coverage.
Just start it up, then forget it's running in the background.
