AI features
What tastytrade's own AI does
tastytrade ships two AI tools, both for tastytrade accounts only: an official MCP server and AI Search.
Official MCP server
Runs on your own computer and lets Claude and other assistants read tastytrade accounts and place orders you confirm first.
Sandbox and read-only modes
A sandbox holds no real money, and a read-only setting blocks every tool that places, changes or cancels orders.
AI Search
Search in plain words for symbols that fit an interest you describe, inside the tastytrade web platform.
Where Walnut fits
tastytrade's MCP server sees tastytrade, from a server you run yourself. Walnut reads it next to every other broker you connect, puts each holding against the S&P 500, places the buys you approve, and works on the web, on a phone, or in Claude or ChatGPT.
Pricing
What tastytrade costs

Everything else people ask about tastytrade, answered plainly.
Short answer
It suits beginners who want to learn options. Stock and ETF trades cost nothing, options cost $1 a contract to open and nothing to close, and tastytrade offers free courses. Someone who only wants to buy and hold index funds will find most of the platform built for someone else.
tastytrade sorts accounts by trading permission, from cash and Limited accounts up to the Basic and Works margin levels. Riskier strategies, such as selling uncovered options, sit at the higher levels, and every permission level is subject to tastytrade's suitability requirements and approval.
The platform shows a lot about each trade and less about the portfolio as a whole. Whether your stocks have kept up with the S&P 500, or one name has grown into a fifth of the account, is the part an AI that reads the account can add.

Short answer
Yes, to Claude. tastytrade's official MCP server, published August 2026, works with clients including Claude Desktop, Claude Code, Cursor, VS Code and Perplexity. You run it on your own computer, and every order needs a confirmation before it is sent.
Setting it up means cloning the server, building it with Node.js and creating OAuth credentials in your tastytrade settings. Walnut takes a different route: you sign in at tastytrade once, Walnut's read-only connector works in Claude and ChatGPT with no API key and no server to run, and buys are previewed and confirmed inside Walnut.
