+# Interactive Brokers
+
+Cursor plugin that connects agents to [Interactive Brokers](https://www.interactivebrokers.com/en/trading/ai-integrations.php) through Interactive Brokers's official remote [Model Context Protocol](https://modelcontextprotocol.io/) server.
+
+Review positions, balances, P&L, and draft trade instructions.
+
+## Install
+
+1. Open **Cursor Settings → Plugins**.
+2. Search for **Interactive Brokers**.
+3. Click **Install**, then complete the Interactive Brokers sign-in prompt.
+
+Or run `/add-plugin interactive-brokers` in chat.
+
+## MCP
+
+```json
+{
+  "mcpServers": {
+    "interactive-brokers": {
+      "type": "http",
+      "url": "https://api.ibkr.com/v1/api/mcp-public"
+    }
+  }
+}
+```
+
+Auth is OAuth. Cursor prompts for Interactive Brokers sign-in when the plugin connects — there is no client ID or personal access token to configure.
+
+## Before you connect
+
+You need an Interactive Brokers account. You authorize one specific account during sign-in. Not available to clients in India or Japan.
+
+## What agents can do
+
+| Category | Capabilities |
+| --- | --- |
+| Accounts | Balances, summaries, positions, and portfolio allocation |
+| Activity | Orders, trades, and historical transactions |
+| Market data | Price snapshots and history; contract search |
+| Instructions | Draft trade instructions for review in IBKR's AI Instructions tab |
+
+The hosted runtime is the source of truth for tool names and schemas.
+
+## Notes
+
+- Trade instructions never become live orders automatically; you review and submit them inside an IBKR platform.
+- IBKR recommends the `mcp-public` endpoint for custom clients; Grok's catalog lists `/mcp`, which shares the same authorization server.
+- Revoke access from **Client Portal → Settings → Manage Third-Party Consents**.
+
+## Docs
+
+- IBKR AI integrations: https://www.interactivebrokers.com/en/trading/ai-integrations.php
+- Server URL: https://api.ibkr.com/v1/api/mcp-public
+
+Logo is Interactive Brokers's official mark.
