The TON Access MCP Server provides a production-ready implementation of the Model Context Protocol (MCP) for the TON blockchain. This server enables AI assistants to interact with TON blockchain data by offering standardized context, tools, and prompts following Anthropic's open protocol specification.

Features

  • Full MCP Implementation: Implements the complete MCP specification for connecting AI assistants to the TON blockchain
  • Decentralized Access: Uses multiple nodes for reliability and decentralization
  • Health Checking: Automatically checks node health and selects healthy nodes
  • Load Balancing: Uses weighted random algorithm to distribute requests
  • Multiple Networks: Supports both mainnet and testnet
  • Multiple Protocols: Supports different RPC protocols (TonCenter HTTP API v2, TonHub HTTP API v4)

Installation

To install the TON Access MCP Server, follow these steps:

# Clone the repository
git clone https://github.com/your-org/ton-access-mcp.git
cd ton-access-mcp

# Install dependencies
npm install

# Build the project
npm run build

# Start the server
npm start

Quick Start

Here's how to create and start the server using TypeScript:

import { TonAccessMCPServer } from 'ton-access-mcp';

// Create and start the server
const server = new TonAccessMCPServer({
  port: 3000,
  host: 'localhost'
});

server.start().then(() => {
  console.log('TON Access MCP Server is running on http://localhost:3000');
});

Available Tools

The TON Access MCP server provides several tools for interacting with the TON blockchain:

Blockchain Query Tools

  • ton.getBalance: Get the balance of a TON wallet address
  • ton.getTransaction: Get details of a TON blockchain transaction
  • ton.getBlock: Get details of a TON blockchain block
  • ton.callGetter: Call a getter method on a TON smart contract
  • ton.getMasterchainInfo: Get current information about the TON masterchain
  • ton.getAccountState: Get the current state of a TON account

Configuration Options

When initializing the TonAccessMCPServer, you can configure the following options:

  • port: The port number for the server (default: 3000)
  • host: The hostname for the server (default: 'localhost')

For more advanced configuration, refer to the documentation in the docs directory of the repository.

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "ton-access" '{"command":"npx","args":["-y","ton-access-mcp"]}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "ton-access": {
            "command": "npx",
            "args": [
                "-y",
                "ton-access-mcp"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

  • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
  • Windows: %APPDATA%\Claude\claude_desktop_config.json
  • Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "ton-access": {
            "command": "npx",
            "args": [
                "-y",
                "ton-access-mcp"
            ]
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
