Wechat Dev Mcp
Overview
WeChat Developer Tools MCP Server
This is a Model Context Protocol (MCP) server that connects to WeChat Developer Tools via miniprogram-automator. It allows you to control the IDE and the mini-program from an MCP client (like Claude Desktop or an AI agent).
Prerequisites
- Node.js: Version 18+ is recommended (though it may work on older versions with some polyfills, this project is set up for modern Node).
- WeChat Developer Tools: Must be installed and running.
- Enable Automation: In WeChat Developer Tools, go to Settings -> Security Settings and enable Service Port (CLI/HTTP invocation).
Quick Start
Using with Claude Desktop (Recommended)
Add the following to your claude_desktop_config.json (e.g., ~/Library/Application Support/Claude/claude_desktop_config.json on macOS):
{
"mcpServers": {
"wechat-devtools": {
"command": "npx",
"args": [
"-y",
"wechat-dev-mcp"
]
}
}
}
Manual Installation
To install globally:
npm install -g wechat-dev-mcp
Then configure:
{
"mcpServers": {
"wechat-devtools": {
"command": "wechat-dev-mcp",
"args": []
}
}
}
