MCP Server Setup

Trafexia features an integrated MCP (Model Context Protocol) Server that communicates via SSE (Server-Sent Events). This allows AI assistants (such as Claude Desktop, Cursor, and Copilot) to inspect and reason about captured network traffic logs directly.

1. How It Works

When enabled in Trafexia's Desktop Settings:

• The desktop app starts a local SSE-based server on port 8890.
• The endpoint is exposed at http://localhost:8890/sse.
• Large Language Models (LLMs) can call tools exposed by this server to read captured request details or clear logging histories.

2. Supported Tools

Trafexia's MCP Server exposes 3 main tools for LLM agents:

1. list_requests:
   • Description: Lists captured HTTP/HTTPS request headers and properties, sorted descending by timestamp.
   • Parameters: limit (max number of requests), search (filter by URL/Host/Path), method (filter by GET/POST/etc).
2. get_request_details:
   • Description: Retrieves full request/response header and body content for a specific transaction ID.
   • Parameters: id (numeric request ID, required).
3. clear_requests:
   • Description: Clears all request logs from Trafexia's local database.

3. Configuration for Claude Desktop

To add Trafexia tools into Claude Desktop:

1. Open or create the Claude Desktop config file:
   • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
   • Windows: %APPDATA%\Claude\claude_desktop_config.json
2. Add trafexia to the mcpServers object:

{
  "mcpServers": {
    "trafexia": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-sse",
        "http://localhost:8890/sse"
      ]
    }
  }
}

3. Restart Claude Desktop. The MCP connection plug icon will light up, allowing you to ask queries like: "Show me the latest API calls captured by Trafexia."

4. Configuration for Cursor IDE

Cursor allows integrating MCP servers to let code assistants build models based on live API calls:

1. Open Cursor Settings > Features > scroll down to MCP.
2. Click "+ Add New MCP Server".
3. Fill in the options:
   • Name: Trafexia
   • Type: Select SSE
   • URL: Enter http://localhost:8890/sse
4. Click Save. The server status will show a green dot (Active). You can now reference @Trafexia in Cursor Chat to write API integration code using real payloads.
