📦 Installation

Configuration 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 chosen RPC endpoint
      }
    }
  }
}

2. Restart Cline to load the new MCP server.

💻 Usage Examples

After configuration, you can interact with the Solana blockchain in Cline using natural language. Here are some example queries:

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

Environment Variables

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