An MCP server that automates WeChat on macOS using the Accessibility API and screen capture. It enables LLMs to interact with WeChat chats programmatically. ## Features - 📨 Fetch recent messages from any chat (contact or group) - ✍️ Send automated replies based on chat history - 📷 Publish text-only Moments posts, with optional draft-only mode - 👥 Add contacts using WeChat ID with configurable privacy - 🔍 Smart chat search with exact name matching - 🤖 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 ⚠️ **Important**: Grant Accessibility permissions to your terminal: 1. Open **System Settings → Privacy & Security → 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 # Run with HTTP transport wechat-mcp --transport streamable-http # Run with SSE transport wechat-mcp --transport sse ``` ### Available MCP Tools - **`fetch_messages_by_chat`** - Get recent messages from a chat - **`reply_to_messages_by_chat`** - Send a reply to a chat - **`add_contact_by_wechat_id`** - Add a new contact using a WeChat ID and send a friend request - **`publish_moment_without_media`** - Publish a text-only Moments post (no photos or videos); optionally only prepare a draft without posting via `publish=False` See [detailed API documentation](docs/detailed-guide.md) for full tool specifications. ## Claude Code Sub-Agents This project includes 5 intelligent sub-agents designed specifically for WeChat automation.
