Chatroost — unofficial Telegram MCP server: MCP server

What Chatroost — unofficial Telegram MCP server does

According to its repository: “Unofficial Telegram MCP server — read, search, reply and react in your own Telegram account.”

The Model Context Protocol (MCP) is a standard plug between an AI agent and an outside service: once the server is connected, its tools show up in the agent, which decides when to call them. Chatroost — unofficial Telegram MCP server is listed under Code execution, a category of 32 servers in the directory, where it ranks #21 by stars.

Topics declared by the repository: ai-tools, claude, gramjs, mtproto, telegram, typescript.

Installing and connecting Chatroost — unofficial Telegram MCP server

Distribution modes declared in the official MCP registry:

• npm package (Node.js, usually started with npx)
• remote server (streamable-http): you connect to it by URL, with nothing to install locally

It works with any MCP-compatible client (Claude Desktop, Claude Code, Cursor, VS Code, Codex and most recent agents). You add one entry to the client's MCP configuration: server name, start command or URL, environment variables. Project language: TypeScript.

The registry lists 2 secret variables to provide (API key, access token). Keep them in the client's environment variables, never in a shared file or a repository.

Security: what to check

Connecting an MCP server means installing software that talks straight to your agent: it runs with your rights and the model trusts its tool descriptions. The risk therefore depends on what it can touch and how far its code can be trusted.

Points found for Chatroost — unofficial Telegram MCP server:

• System access: the Code execution category gives the agent control over files, a terminal, code or a browser. A booby-trapped instruction in content the agent reads (prompt injection) can then turn into an action.
• Secrets: the server acts with your credentials. Create a dedicated key with minimum rights and an expiry date.

Good practice: grant only the rights needed (least privilege), require human approval for irreversible actions, and run the AI agent security check.

Project activity and maintenance

Created on March 10, 2026, the mcp-telegram/mcp-telegram repository has 56 stars and 21 forks, with 16 open issues. It has more stars than 54% of the servers in the directory. It received changes this month. Version published in the registry: 1.43.6 (October 13, 2026).

Stars measure attention, not quality: a recent, heavily promoted project can collect them fast, while a useful but niche server will have few.
