MCP

Explain how to use MCP on Proxyman with Cursor or Claude Code

1. What is Proxyman MCP?

Proxyman MCP (Model Context Protocol) is a feature that enables AI assistants (Claude, Cursor, and other MCP-compatible tools) to directly interact with the Proxyman macOS app. It allows AI to inspect HTTP traffic, create debugging rules, and control Proxyman - all through natural language conversations.

The architecture consists of two components:

• MCP HTTP Server - Runs inside Proxyman app on localhost with token-based authentication

• MCP CLI Server - A stdio-based MCP server that AI tools connect to, which forwards commands to Proxyman

✅ Example Prompts

• Show me the last 10 API requests to api.example.com

• Create a breakpoint for all POST requests to /api/users

• Export the failed request as a cURL command

• Enable SSL proxying for *.stripe.com

• Create a new Script to change the status code, headers, body.

• Create Map Local, Breakpoint Tools with given URL

2. Benefits

Benefit	Description
AI-Powered Debugging	Ask AI to analyze captured traffic, find specific requests, or explain API responses
Hands-Free Rule Creation	Create breakpoints, map local/remote rules through conversation
Faster Workflow	Export cURL commands, filter flows, and manage sessions without switching context
Secure by Design	Localhost-only server with per-session token authentication
IDE Integration	Works seamlessly with Cursor and other MCP-compatible tools

3. How to Use

Setup

1. Enable MCP in Proxyman

   • Open Proxyman → Settings → MCP

   • Toggle Enable MCP Server

2. Configure your MCP client (e.g., Cursor, Claude Desktop)

   Add to your MCP configuration:

• Production Version:

{
  "mcpServers": {
    "proxyman": {
      "command": "/Applications/Proxyman.app/Contents/MacOS/mcp-server"
    }
  }
}

• Setapp Version

{
  "mcpServers": {
    "proxyman": {
      "command": "/Applications/Setapp/Proxyman.app/Contents/MacOS/mcp-server"
    }
  }
}

1. Start using

• Ensure Proxyman is running

• Ask your AI assistant to interact with Proxyman
