Execute trades inside Claude Desktop

Stop switching tabs to manage your portfolio. You can use `place_new_order` and `activate_pending_order` to send buy or sell instructions while discussing market moves with your agent. This workflow keeps your trading logic inside the chat window. Your agent handles the order flow while you monitor the status via `list_brokerage_orders`.

Pull real-time market data into Claude Desktop

Get current bid and ask prices instantly. Use `get_latest_quote` to grab the numbers you need before you make a decision. Finding the right asset is just as easy. Use `search_market_instruments` to look up ISINs or ticker symbols without leaving the Claude Desktop interface.

Manage your brokerage account in Claude Desktop

Keep an eye on your positions without logging into a separate dashboard. Use `list_active_positions` to see exactly what you hold right now. Check your buying power with `get_brokerage_account`. It provides the balance details you need to ensure your next trade goes through without issues.

Common questions about lemon.markets MCP in Claude Desktop

You need to add the server configuration to your local config file. Open your Claude Desktop settings, paste the server details, and restart the app to initialize the connection.

Yes, as long as the market is open. You invoke the trading tools directly, and the server communicates with the brokerage API to execute your orders.

Your credentials stay local on your machine. The MCP server runs as a subprocess, ensuring your keys aren't exposed to third-party services.

The tool will return an error response immediately. You can then use `list_brokerage_orders` to check the status or cancel the failed attempt.

No. The server only fetches data when you ask for it. Your sensitive portfolio data is never saved by the agent, only displayed in your chat session.
