🔍 MCP Inspector

To inspect and debug your MCP server, you can use the MCP Inspector tool:

npx @modelcontextprotocol/inspector

This will launch the MCP Inspector interface, allowing you to:

• Monitor MCP messages in real-time
• Debug tool and resource calls
• Inspect server responses
• Test server functionality

🌐 Server Transport

The server uses Server-Sent Events (SSE) transport, making it compatible with:

• Web browsers and HTTP clients
• Traditional MCP clients
• Custom integrations

Connection Details

• SSE Endpoint: http://127.0.0.1:8000/sse (for establishing SSE connection)
• Message Endpoint: http://127.0.0.1:8000/messages/ (for posting MCP messages)
• Transport: SSE (Server-Sent Events)
• Protocol: MCP (Model Context Protocol)

Web Client Example

// Establish SSE connection
const eventSource = new EventSource('http://127.0.0.1:8000/sse');
eventSource.onmessage = function(event) {
    const mcpMessage = JSON.parse(event.data);
    // Handle MCP protocol messages
};

// Send MCP messages
async function sendMCPMessage(message) {
    const response = await fetch('http://127.0.0.1:8000/messages/', {
        method: 'POST',
        headers: {
            'Content-Type': 'application/json',
        },
        body: JSON.stringify(message)
    });
    return response.json();
}
