+### You.com 联网搜索与研究
+
+通过 You.com MCP 服务器接入实时联网搜索、网页内容读取、可引用的多源研究和财经研究工具。`@youdotcom-oss/mcp` 是一个轻量 STDIO 桥接，把本地 MCP 请求转发到托管在 `https://api.you.com/mcp` 的远程服务器；首轮对话后，模型即可看到 `mcp__ydc__you-search` 等工具。

+```json
+{
+  "mcpServers": {
+    "ydc": {
+      "command": "npx",
+      "args": ["-y", "@youdotcom-oss/mcp"],
+      "env": {
+        "YDC_API_KEY": "ydc-...",
+        "YDC_ALLOWED_TOOLS": "you-search,you-contents,you-research,you-finance"
+      }
+    }
+  }
+}
+```
+
+如果想先体验联网搜索、不立刻注册账号，可以把 `YDC_PROFILE` 设为 `free`（免账号、免 Key，仅暴露 `you-search`，每天 100 次查询上限）：
+
+```json
+{
+  "mcpServers": {

+### You.com Web Search & Research
+
+Connects you to You.com's real-time web search, page content extraction, citable multi-source research, and finance research via the hosted You.com MCP server at `https://api.you.com/mcp`. `@youdotcom-oss/mcp` is a minimal STDIO bridge that forwards local MCP traffic to the remote server. After the first message, the model sees tools such as `mcp__ydc__you-search`.
+
+```json
+{
+  "mcpServers": {
+    "ydc": {
+      "command": "npx",
+      "args": ["-y", "@youdotcom-oss/mcp"],

+        "YDC_ALLOWED_TOOLS": "you-search,you-contents,you-research,you-finance"
+      }
+    }
+  }
+}
+```
+
+To try web search without signing up first, set `YDC_PROFILE` to `free` (no account, no API key; exposes only `you-search`, capped at 100 queries/day):
+
+```json
+{
+  "mcpServers": {
