Tolk MCP server

Lets your AI write, check, compile and prepare TON smart contracts in Tolk right inside the chat.

This is a small helper that plugs the Tolk compiler into your AI assistant. Tolk is a language for writing smart contracts on the TON blockchain. If you are learning TON or writing contracts, this lets you stay in the chat instead of switching between tools.

What is an MCP server? The 30-second version

On its own, your AI can only chat. An MCP server is a small helper program that gives your AI a new skill or a connection to another tool. This one connects your AI to the Tolk compiler for TON smart contracts. Once it is set up, your AI can compile your code, check it for mistakes, and prepare a link to deploy it, all when you ask.

What this MCP server does

You paste some Tolk code into the chat and ask your AI to compile it. The AI sends the code to this helper, which runs the Tolk compiler on your computer. The compiler checks the code and turns it into the format TON needs. The AI then shows you the result, the contract's code hash, and the compiler version. If you want to put the contract on the blockchain, the AI can also build a deployment link for your wallet.

Flow diagram: you ask your AI “Compile this Tolk contract and check for errors”, on your own computer the Tolk MCP server works with your computer, and you get back compiler output and code hash.

What you can do with it

Compile a Tolk smart contract and see the result in the chat
Check your Tolk code for syntax and type errors before compiling
Ask for the version of the Tolk compiler being used
Generate a ton:// or Tonkeeper link to deploy a compiled contract
Get help writing a new contract from a plain description
Ask for a security review of a contract you already have
Get help fixing a compilation error

Try asking your AI

“Compile this Tolk smart contract and tell me if there are any errors”
“Write a simple counter contract for TON that stores a number and lets anyone increment it”
“Review this contract for security issues”
“I'm getting this error when compiling: unexpected token 'fun'. Here's my code, can you fix it?”
“Generate a deployment link for the contract we just compiled”

What it gives back to you

You get answers in the chat, not files on your desktop. For a compile, you see the compiler output, the code hash, and the compiler version. For a syntax check, you get a short list of errors or a note that everything is fine. For a deploy link, you get a ton:// link and a Tonkeeper link you can open in your wallet.

Before you start

What you need

Node.js version 18 or newer on your computer
An MCP client such as Claude Desktop, Claude Code, Cursor, Windsurf or VS Code with Copilot

Good to know

A deployment link can lead to spending real TON when you open it in your wallet, so check the amount and the contract address before confirming.

Install it with your AI

Add Tolk MCP server to your AI, no technical skills needed

You don't install anything by hand. You copy one prompt, paste it into an AI that can work on your computer, and it checks, installs and connects the server for you, asking you when it needs something.

Sign in to get the install prompt

Members get a ready-made prompt that lets the Claude desktop app check Tolk MCP server, install it and connect it for them, step by step. You don't need any technical skills: you copy, paste and answer a few questions. Your connected AI can also find and install any of the 4,066 MCP servers here for you.
