+# Lark
+
+Cursor plugin that connects agents to [Lark](https://www.larksuite.com) through Lark's official remote [Model Context Protocol](https://modelcontextprotocol.io/) server.
+
+Search, create, fetch, and update Lark Docs, work with doc comments and files, and read groups and messages in the signed-in Lark account.
+
+## Install
+
+1. Open **Cursor Settings → Plugins**.
+2. Search for **Lark**.
+3. Click **Install**, then complete the Lark sign-in prompt.
+
+Or run `/add-plugin lark` in chat.
+
+## MCP
+
+```json
+{
+  "mcpServers": {
+    "lark": {
+      "type": "http",
+      "url": "https://mcp.larksuite.com/mcp"
+    }
+  }
+}
+```
+
+Auth is MCP OAuth. Cursor discovers Lark's authorization server from the server URL when the plugin connects and prompts for Lark sign-in — there is no app ID, app secret, access token, or custom header to configure.
+
+## Before you connect
+
+You need a Lark Suite account. Requests are rejected until sign-in completes.
+
+This plugin talks only to `https://mcp.larksuite.com/mcp`, the endpoint for Lark Suite, the international product. Accounts on China-region Feishu use a different server (`https://mcp.feishu.cn/mcp`) and are not covered by this plugin.
+
+## What agents can do
+
+| Category | Capabilities |
+| --- | --- |
+| Docs | Search, create, fetch, and update docs, list docs, and read and write doc comments |
+| Messages | Search groups, list group members, read messages and threads, and check read status |
+| People and files | Look up the signed-in user, search users, and fetch files |
+
+The hosted runtime is the source of truth for the tool names and schemas it advertises; see Lark's MCP documentation for the current list.
+
+## Notes
+
+- Tool calls run as the Lark user who authorizes the connection and cannot exceed that user's own permissions.
+- This is a URL-only connector to Lark's hosted server. It does not wrap the local `@larksuiteoapi/lark-mcp` stdio server, which is configured separately with an app ID and secret.
+- Revoke access at any time from your Lark account.
