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
      }
    }
  }
}
  1. 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 …”
