Solana Model Context Protocol (MCP) Demo

This repository demonstrates a simple implementation of a Model Context Protocol (MCP) server for Solana development.

What is MCP?

The Model Context Protocol (MCP) is a standardized interface for AI models to interact with tools and resources. This demo showcases a simple MCP server implementation that provides:

1. Basic RPC methods for Solana (getBalance, getAccountInfo, getTransaction)
2. Some helpful prompts for Solana development

Prerequisites

• Node.js (v16 or higher recommended)
• pnpm package manager (v9.10.0 or compatible)

Installation

Clone this repository and install dependencies:

git clone https://github.com/solana-foundation/solana-dev-mcp.git
cd solana-dev-mcp
pnpm install

To run this server in the MCP inspector, use:

npx @modelcontextprotocol/inspector ts-node index.ts

Getting Started

1. Explore the code: The main implementation is in index.ts, which sets up an MCP server with simple fetching tools and some prompts.

2. Modify the server: You can extend the server by adding more tools, resources, and prompts.

3. Get ideas for extensions: Check out the Ideas Extending MCP for Solana Development section to get inspiration for new tools and resources to add.

Example Usage

This section explains how to use the Solana MCP server in Claude. Follow the same steps to use the Solana MCP server in Windsurf and Cursor.

Generate the configuration file

To use this Solana MCP server, you need to generate a configuration file that Claude can use to connect to the server. Run one of the following commands to generate the configuration file:

• pnpm generate-config if you have ts-node installed globally
• pnpm build && pnpm generate-config:js if you don’t have ts-node installed globally

This will print a JSON config with the following content:

If you have ts-node:

{
  "mcpServers": {
    "solana-dev": {
      "command": "ts-node",
      "args": ["/index.ts"]
    }
  }
}

If you don’t have ts-node installed globally:

{
  "mcpServers": {
    "solana-dev": {
      "command": "node",
      "args": ["/dist/index.js"]
    }
  }
}

Project Structure

• index.ts - Main server implementation
• package.json - Project dependencies and metadata
• tsconfig.json - TypeScript configuration

Ideas Extending MCP for Solana Development

This MCP server implementation provides a foundation that you can extend or fork for your own Solana development needs. Here are some ideas to get you started:
