-# Reddit 代理配置指南
+# Reddit 配置指南
 
 ## 功能说明
-Reddit 封锁了大量服务器 IP，直接访问会返回 403。需要 ISP 代理（Residential/ISP Proxy）才能读取完整的 Reddit 帖子和评论。
 
-**注意**：即使没有代理，也可以通过 Exa 搜索找到 Reddit 内容（只需要配 Exa API key）。代理只是用于读取完整帖子+评论。
+Reddit 封锁了几乎所有非浏览器的直接访问（包括数据中心和 ISP 代理 IP），JSON API 返回 403。
+
+Agent Reach 通过 **Exa** 实现 Reddit 的搜索和阅读功能：
+- **搜索**：`web_search_exa` + `includeDomains: ["reddit.com"]`
+- **阅读完整帖子+评论**：`crawling_exa` 读取 Reddit URL 的缓存内容
+
+免费，无需代理，无需 API Key。
 
 ## Agent 可自动完成的步骤
 
-1. 检查当前状态：
+1. 检查 Exa 是否可用：
 ```bash
-agent-reach doctor | grep "Reddit"
+agent-reach doctor | grep -E "Reddit|Exa"
 ```
 
-2. 如果用户提供了代理，测试连通性：
+2. 如果 Exa 未安装，自动安装：
 ```bash
-curl -s --proxy "用户提供的代理" \
-  -H "User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36" \
-  "https://www.reddit.com/r/test.json?limit=1" \
-  -o /dev/null -w "%{http_code}"
+npm install -g mcporter
+mcporter config add exa https://mcp.exa.ai/mcp
 ```
-返回 200 = 可用，403 = 代理被封，其他 = 配置错误
 
-3. 写入配置：
-```python
-from agent_reach.config import Config
-c = Config()
-c.set("reddit_proxy", "http://用户名:密码@IP:端口")
+或一键安装：
+```bash
+agent-reach install --env=auto
+```
+
+## 使用示例
+
+搜索 Reddit 内容：
+```bash
+mcporter call 'exa.web_search_exa(query: "python best practices", numResults: 5, includeDomains: ["reddit.com"])'
+```
+
+阅读完整帖子和评论：
+```bash
+mcporter call 'exa.crawling_exa(urls: ["https://www.reddit.com/r/python/comments/xxx/"], maxCharacters: 10000)'
 ```
 
 ## 需要用户手动做的步骤
 
-请告诉用户：
-
-> 要完整阅读 Reddit 帖子和评论，需要一个 ISP 代理（约 $3-10/月）。
->
-> 推荐代理服务商（选一个就行）：
-> 1. **Smartproxy** (https://smartproxy.com) — ISP 代理，按流量计费
-> 2. **Bright Data** (https://brightdata.com) — 大厂，ISP 代理
-> 3. **IPRoyal** (https://iproyal.com) — 便宜，适合入门
-> 4. **ProxyEmpire** (https://proxyempire.io) — 有 Reddit 专用代理
->
-> 购买时选择：
-> - 类型：**ISP Proxy**（不要选 Datacenter，会被封）
-> - 地区：**美国**
-> - 协议：**HTTP**
->
-> 购买后你会得到一个代理地址，格式类似：
-> `http://用户名:密码@IP地址:端口号`
->
-> 把这个地址发给我就行。
->
-> ⚠️ 如果不想花钱，可以跳过。我仍然可以通过搜索引擎找到 Reddit 上的内容，只是不能读完整的帖子和评论。
-
-## Agent 收到代理后的操作
-
-1. 测试代理：用 curl 测试 reddit.com 是否返回 200
-2. 如果成功，写入配置：`config.set("reddit_proxy", proxy_url)`
-3. 反馈："✅ Reddit 完整阅读已开启！现在我可以读取 Reddit 帖子和所有评论了。"
-4. 如果失败，告诉用户："❌ 这个代理无法访问 Reddit，请检查代理是否有效，或换一个试试。"
+无。Exa 通过 `agent-reach install --env=auto` 自动配置。
