Solana MCP Server 🌱

What is Solana MCP Server?

A Model Context Protocol (MCP) server that enables interaction with the Solana blockchain using your own private key. It is designed for developers and users who want to query data and execute transactions on Solana via MCP‑capable clients.

How to use Solana MCP Server?

Install automatically via Smithery (npx -y @smithery/cli install @Grandbusta/solana-mcp --client claude) or manually by cloning the repository, installing dependencies (npm install), and building (npm run build). After creating a keypair.json file with your private key, run the server using /path/to/run.sh /path/to/keypair.json. Integration with Cursor is done by adding a new MCP server with that command.

It acts as a bridge between MCP clients (like Claude Desktop or Cursor) and the Solana blockchain, allowing you to perform read and write operations using your own keypair.
