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.
