**To configure WeChat article reading in Agent Reach, install the Exa MCP search backend via mcporter, set up the Camoufox browser and miku_ai extraction libraries, and clone the wechat-article-for-ai helper repository.**

Agent Reach provides a dedicated WeChat channel that enables searching and reading public WeChat Official Account articles. This workflow integrates the Exa search API for content retrieval and Camoufox for headless browser automation when needed. Following the complete setup ensures full access to both search and read capabilities for WeChat content.

## Run the Automated Installer

Agent Reach provides a single command that executes the complete configuration workflow. Running `agent-reach install --channels=wechat` triggers three internal routines defined in [`agent_reach/cli.py`](https://github.com/Panniantong/Agent-Reach/blob/main/agent_reach/cli.py):

### Configure the Exa MCP Backend

The installer first ensures the **Exa** MCP (Model Context Protocol) search service is configured. In [`agent_reach/cli.py`](https://github.com/Panniantong/Agent-Reach/blob/main/agent_reach/cli.py), the `_install_mcporter()` function (lines 1212-1254) checks for the `mcporter` binary and runs:

```bash
mcporter config add exa https://mcp.exa.ai/mcp

```

This establishes the free Exa search endpoint as the primary backend for WeChat article discovery and full-text extraction.

### Install WeChat Python Packages

Next, the `_install_wechat_deps()` function (lines 992-1022) automatically detects and installs required packages:

- **camoufox**: GeoIP-enabled headless browser for JavaScript rendering
- **miku_ai**: Article text extraction engine
- **markdownify**, **beautifulsoup4**, **httpx**: HTML parsing and HTTP utilities

The installer builds the appropriate `pip install` command and verifies successful imports before proceeding.

### Clone the Helper Repository

Finally, the installer clones the **wechat-article-for-ai** repository into `~/.agent-reach/tools/wechat-article-for-ai` (lines 842-860). This external CLI tool contains the low-level logic for navigating WeChat's public article infrastructure and extracting clean text content.

## Verify the Installation

Once installation completes, run the diagnostic command to verify all components are properly integrated:

```bash
agent-reach doctor

```

This executes `WeChatChannel.check()` in [`agent_reach/channels/wechat.py`](https://github.com/Panniantong/Agent-Reach/blob/main/agent_reach/channels/wechat.py) (lines 38-63), which returns one of two states:

- **"ok"**: Both Exa and Camoufox are present, enabling full search and read capabilities
- **"warn"**: Only one component is available, indicating limited functionality

The check ensures that the MCP server configuration, Python dependencies, and helper tool are all accessible before attempting operations.

## Read and Search WeChat Articles

With the channel reporting "ok" status, you can process WeChat content through either the Python API or CLI interface.

### Using the Python Library

Import the core AgentReach class and invoke the read method with any public WeChat article URL:

```python
from agent_reach.core import AgentReach

ar = AgentReach()
article = ar.read("https://mp.weixin.qq.com/s?__biz=...")
print(article)

```

The `WeChatChannel.read()` implementation in [`agent_reach/channels/wechat.py`](https://github.com/Panniantong/Agent-Reach/blob/main/agent_reach/channels/wechat.py) prefers Exa for full-text extraction, automatically falling back to Camoufox when the MCP service cannot retrieve the content.

### Using the Command Line Interface

For quick operations or shell scripting, use the CLI commands:

```bash

# Fetch a specific article

agent-reach read https://mp.weixin.qq.com/s?__biz=...

# Search for articles by keyword

agent-reach search wechat "machine learning conference"

```

The CLI routes requests through the central logic in [`agent_reach/core.py`](https://github.com/Panniantong/Agent-Reach/blob/main/agent_reach/core.py), which selects `WeChatChannel` when detecting WeChat URL patterns via the `can_handle` method.

## Summary

- **Install the Exa backend**: The `_install_mcporter()` function in [`agent_reach/cli.py`](https://github.com/Panniantong/Agent-Reach/blob/main/agent_reach/cli.py) configures the MCP search service at `https://mcp.exa.ai/mcp`
- **Install Python dependencies**: `_install_wechat_deps()` handles camoufox, miku_ai, and supporting libraries automatically
- **Clone the helper tool**: The installer pulls wechat-article-for-ai to `~/.agent-reach/tools/` for low-level article fetching
- **Verify with doctor**: Execute `agent-reach doctor` to trigger `WeChatChannel.check()` and confirm "ok" status
- **Start reading**: Use `agent-reach read <url>` or the Python `AgentReach().read()` method to extract article content

## Frequently Asked Questions

### What is the purpose of the Exa MCP service in WeChat article reading?

The **Exa** MCP (Model Context Protocol) service provides the primary search and content extraction backend for WeChat articles. According to the source code in [`agent_reach/cli.py`](https://github.com/Panniantong/Agent-Reach/blob/main/agent_reach/cli.py), the `_install_mcporter()` function configures Exa to handle both article discovery and full-text retrieval. When Exa is unavailable, the system falls back to Camoufox for direct browser rendering.

### Why does the installation require both Exa and Camoufox?

**Exa** serves as the preferred method for content extraction due to its specialized search capabilities and MCP integration, while **Camoufox** acts as a fallback for articles that require JavaScript rendering or when Exa cannot access specific content. The `WeChatChannel.check()` method in [`agent_reach/channels/wechat.py`](https://github.com/Panniantong/Agent-Reach/blob/main/agent_reach/channels/wechat.py) verifies both components are present to report "ok" status, ensuring robust access to WeChat's public article ecosystem.

### Where does Agent Reach store the WeChat helper tool?

Agent Reach clones the **wechat-article-for-ai** repository into `~/.agent-reach/tools/wechat-article-for-ai` during the installation process. This path is hardcoded in [`agent_reach/cli.py`](https://github.com/Panniantong/Agent-Reach/blob/main/agent_reach/cli.py) lines 842-860 within the installation routine. The helper contains the low-level CLI logic for fetching articles that the main Agent Reach channel interfaces with.

### How do I troubleshoot a "warn" status from the WeChat channel?

A "warn" status from `agent-reach doctor` indicates that only one of the two required components (Exa or Camoufox) is properly installed. Check the output logs from the installation commands to see which dependency failed. You can manually verify Exa configuration by checking `mcporter` settings, or reinstall specific components by running `agent-reach install --channels=wechat` again to trigger the `_install_wechat_deps()` and `_install_mcporter()` routines.
