Toss Securities MCP server

This is a helper that connects your AI assistant to your Toss Securities account. Once it is set up, you can ask your AI things like the current price of a Korean or US stock, your holdings, or the exchange rate, and it will fetch the answer for you. It is handy for people who already trade on Toss Securities and want to ask questions in plain language instead of clicking around.

What this MCP server does

You ask your AI a question in plain words, like the price of Samsung or your current holdings. The AI uses this helper, which talks to the Toss Securities Open API on your behalf. The helper sends back the numbers or list it found, and the AI shows it to you in the chat. For orders, the helper first makes a preview, shows it to you, and only sends the real order after you clearly confirm it.

Try asking your AI

• “What is the current price of Samsung Electronics?”
• “Show me my holdings and how much I am up or down.”
• “How much buying power do I have in USD right now?”
• “Prepare a buy order for 10 shares of Apple and show me the details before I confirm.”

What it gives back to you

You get back plain answers in the chat, like a price, a list of your holdings with profit and loss, or a small table of recent trades. For orders, you first get a preview showing the stock, quantity, and price, and nothing is sent until you say yes. After you confirm, the helper submits the order and tells you the result.
