ProxyPin Server

MCP Badge

ProxyPin MCP Server is based on the Model Context Protocol (MCP). It works with the open source project ProxyPin to expose your local capture history to MCP-capable clients.

Docs: English | 中文

Features

• Read local ProxyPin history (HAR)
• List/search/detail tools for captured requests
• API structure analysis and code generation
• Works with mainstream MCP clients (Windsurf / Cursor / Claude Desktop / Codex)

Prerequisites

1. Install and open ProxyPin
2. In ProxyPin History settings, enable “Cache Date” (required)
3. Ensure some capture history exists
4. Node.js (for npx) and uv (launcher supports both uvx and uv tool run)

Installation

Run with npx

npx -y proxypin-mcp@latest

The NPX bridge tries uvx first, then automatically falls back to uv tool run.

Usage

Add the following configuration to your MCP client configuration file:

{
  "mcpServers": {
    "proxypin": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "proxypin-mcp@latest"]
    }
  }
}

[!TIP] If your client does not support type, remove the field.
