Whistle MCP Server

English | 中文

Project Introduction

Whistle MCP Server is a Whistle proxy management tool based on the Model Context Protocol (MCP), allowing AI assistants to directly operate and control local Whistle proxy servers. Through this tool, AI can help users manage rules, groups, values, monitor network requests, replay and modify requests, etc., without requiring manual operation of the Whistle interface. It greatly simplifies the process of network debugging, API testing, and proxy rule management, enabling users to complete complex network proxy configuration tasks through natural language interaction with AI.

Features

• Rule Management: Create, update, rename, delete, and enable/disable Whistle rules
• Group Management: Create, rename, delete groups, and associate operations between rules and groups
• Value Management: Create, update, rename, and delete values, with support for value group management
• Proxy Control: Enable/disable proxy, HTTP/HTTPS interception, HTTP/2 protocol, etc.
• Request Interception: View intercepted network request information, with URL filtering support
• Request Replay: Support for replaying captured requests with custom request parameters
• Multi-Rule Mode: Support for enabling/disabling multi-rule mode
