ProxyPin MCP Server

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"]
    }
  }
}

Variable	Description	Default
PROXYPIN_DATA_DIR	ProxyPin history directory	auto-detect
PROXYPIN_HAR_LIMIT	max HAR files scanned	50

• limit (int, optional, default 20)
• detail (string: summary | key | full)
• domain (string, optional)
• method (string, optional)
• status (int, optional)

get_request

Get a single request detail by ID.

Parameters:

• request_id (string, required)
• include_body (boolean, optional, default true)

search_requests

Search requests by keyword.

Parameters:

• keyword (string, required)
