- βοΈ Send automated replies based on chat history
- π· Publish text-only Moments posts, with optional draft-only mode
- π₯ Add contacts using WeChat ID with configurable privacy
- π Smart chat search with exact name matching
- π€ 5 specialized Claude Code sub-agents for smart WeChat automation
## Quick Start
### Installation
```bash
pip install wechat-mcp-server
```
### Setup with Claude Code
```bash
# If installed via pip
claude mcp add --transport stdio wechat-mcp -- wechat-mcp
# If using uv for development
claude mcp add --transport stdio wechat-mcp -- uv --directory $(pwd) run wechat-mcp
```
Setup with Claude Desktop
```json
// If installed via pip
{
"mcpServers": {
"wechat-mcp": {
"type": "stdio",
"command": "wechat-mcp"
}
}
}
// If using uv for development
{
"mcpServers": {
"wechat-mcp": {
"type": "stdio",
"command": "uv",
"args": [
"--directory",
"{path/to/wechat-mcp}",
"run",
"wechat-mcp"
],
}
}
}
```
Setup with Codex
```bash
# If installed via pip
codex mcp add wechat-mcp -- wechat-mcp
# If using uv for development
codex mcp add wechat-mcp -- uv --directory $(pwd) run wechat-mcp
```
### macOS Permissions
β οΈ **Important**: Grant Accessibility permissions to your terminal:
1. Open **System Settings β Privacy & Security β Accessibility**
2. Add your terminal application (Terminal.app, iTerm2, etc.)
3. Ensure WeChat is running before using the server
## Usage
### Basic Commands
```bash
# Run with default stdio transport
wechat-mcp --transport stdio
