IDE Config MCP Server

A Python-based MCP Server that provides tools for modifying IDE configuration files (currently supports VS Code only). MCP allows Large Language Models (LLMs) to directly call these tools to manipulate IDE settings.

Features

• Get IDE configuration file content
• Update IDE configuration files
• Get configuration item by key
• Set configuration item by key
• Compliant with MCP standard, can be directly called by LLMs

Notes

1. The server automatically accesses the corresponding VS Code configuration file based on the operating system:

   • Windows: %APPDATA%\Code\User\settings.json
   • macOS: ~/Library/Application Support/Code/User/settings.json
   • Linux: ~/.config/Code/User/settings.json

2. Ensure your LLM supports MCP protocol for automatic tool discovery and invocation.
