Solana MCP Server

A Model Context Protocol (MCP) server that provides comprehensive access to Solana blockchain data through Cline. This server implements a wide range of Solana RPC methods, making it easy to query blockchain information directly through natural language conversations.

Setup in Cline

1. Add the following configuration to your Cline MCP settings file (~/Library/Application Support/Code/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json on macOS):

{
  "mcpServers": {
    "solana": {
      "command": "cargo",
      "args": ["run"],
      "cwd": "/path/to/solana-mcp-server",
      "env": {
        "SOLANA_RPC_URL": "https://api.mainnet-beta.solana.com"  // Or your preferred RPC endpoint
      }
    }
  }
}

2. Restart Cline to load the new MCP server.

Usage Examples

Once configured, you can interact with the Solana blockchain through natural language in Cline. Here are some example queries:

• "What's the SOL balance of address Gh9ZwEmdLJ8DscKNTkTqPbNwLNNBjuSzaG9Vp2KGtKJr?"
• "Show me the current slot number"
• "Get information about the latest block"
• "What's the current inflation rate?"
• "Show me the token accounts owned by address ..."

Environment Variables

• SOLANA_RPC_URL: (Optional) The Solana RPC endpoint to use. Defaults to "https://api.mainnet-beta.solana.com" if not specified.
