+# Webull
+
+Cursor plugin that connects agents to [Webull](https://developer.webull.com/apis/docs/AI-friendly-Resources/mcp/) through Webull's official remote [Model Context Protocol](https://modelcontextprotocol.io/) server.
+
+View accounts, positions, orders, watchlists, and market data.
+
+## Install
+
+1. Open **Cursor Settings → Plugins**.
+2. Search for **Webull**.
+3. Click **Install**, then complete the Webull sign-in prompt.
+
+Or run `/add-plugin webull` in chat.
+
+## MCP
+
+```json
+{
+  "mcpServers": {
+    "webull": {
+      "type": "http",
+      "url": "https://api.webull.com/mcp"
+    }
+  }
+}
+```
+
+Auth is OAuth. Cursor prompts for Webull sign-in when the plugin connects — there is no client ID or personal access token to configure.
+
+## Before you connect
+
+You need a Webull account. During sign-in you choose which accounts and capability groups (account info, order query, market data, security master) to expose.
+
+## What agents can do
+
+| Category | Capabilities |
+| --- | --- |
+| Accounts | Balances, account list, and positions |
+| Orders | Open orders, order history, and order detail |
+| Market data | Stocks, crypto, futures, and event contracts: quotes, bars, ticks, rankings |
+| Research | Company profiles, analyst ratings, filings, financial statements, and fund data |
+| Watchlists | Create and manage watchlists |
+
+The hosted runtime is the source of truth for tool names and schemas.
+
+## Notes
+
+- The hosted server is read-only for trading: order placement, modification, and cancellation are only in Webull's local MCP server.
+- Hong Kong accounts use a separate regional endpoint that this plugin does not configure.
+
+## Docs
+
+- Webull Cloud MCP: https://developer.webull.com/apis/docs/AI-friendly-Resources/mcp/
+- Server URL: https://api.webull.com/mcp
+
+Logo is Webull's official mark.
