Common questions

Is Tolk MCP Server safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 9 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code.

What can I use instead?

tolk-mcp-server

MCP server for the Tolk smart contract compiler. Compile, validate, and explore TON smart contracts from any MCP-compatible AI assistant (Claude Desktop, Cursor, Windsurf, etc.).

Features

Tools:

  • get_compiler_version — Returns the Tolk compiler version
  • compile_tolk — Compiles Tolk source code to Fift + BoC with full compiler options (optimization level, stack comments, experimental flags)
  • check_tolk_syntax — Quick syntax validation without full output

Resources:

  • tolk://reference — Tolk language quick reference (syntax, types, differences from FunC)
  • tolk://examples/hello-world — Counter contract example
  • tolk://examples/wallet — Wallet contract example
  • tolk://examples/jetton — Jetton (token) contract skeleton

Prompts:

  • write_smart_contract — Guided prompt for writing a new TON smart contract
  • review_smart_contract — Guided prompt for security review and optimization analysis

Quick Start

Claude Desktop

Add to claude_desktop_config.json:

{

"mcpServers": { "tolk": { "command": "npx", "args": ["-y", "tolk-mcp-server"] } } }

Cursor / Windsurf

Add to your MCP settings:

{

"tolk": { "command": "npx", "args": ["-y", "tolk-mcp-server"] } }

From Source
git clone https://github.com/oxgeneral/tolk-mcp-server.git

cd tolk-mcp-server npm install npm run build npm start

Usage Examples

Compile a contract
> Use the compile_tolk tool to compile this contract:

fun onInternalMessage(myBalance: int, msgValue: int, msgFull: cell, msgBody: slice) { }

get fun hello(): int { return 42; }

The tool returns:

  • Fift assembly code
  • BoC (Bag of Cells) in base64 — ready for deployment
  • Code hash — unique identifier of the compiled code
  • Warnings (if any)
Check syntax quickly
> Use check_tolk_syntax to validate my contract before deploying

Returns OK + code hash, or a detailed error with line/column info.

Multi-file contracts

Pass all files in the sources parameter:

{

"entrypointFileName": "main.tolk", "sources": { "main.tolk": "import \"./utils.tolk\";\nfun onInternalMessage(...) { ... }", "utils.tolk": "fun helper(): int { return 1; }" } }

Standard library imports (@stdlib/*) are resolved automatically by the compiler.

Compiler Options

OptionTypeDefaultDescription
optimizationLevel0-220 = none, 1 = basic, 2 = full
withStackCommentsboolfalseAdd stack layout comments to Fift output
experimentalOptionsstring""Space-separated experimental compiler flags
