The Core Difference: Broker vs Broker-Agnostic
Public.com is a broker that has bolted an MCP server onto its own API. Great if your account is already at Public and you only use Claude Desktop. To trade elsewhere you either open a second account at Public or look for a different tool.
Tradewink is not a broker. It's an AI layer that connects whichever broker you already use to whichever AI client you prefer. Your funds stay at Alpaca, Tradier, Schwab, or wherever — Tradewink only sees what you authorize and only routes orders you approve.
Neither model is better for every trader. If you want a single broker with AI baked in, Public is simpler. If you want to bring AI to the broker you already trust, Tradewink is the fit.

Frequently Asked Questions
Is Tradewink a replacement for Public.com?
No — Tradewink is not a broker and doesn't hold your money. Tradewink is an AI trading layer that connects to the broker you already use (Alpaca, Tradier, Interactive Brokers, Schwab, Webull, Moomoo, TradeStation, or tastytrade). Public.com is a broker with a built-in Claude Desktop MCP server. If you already have an account at any of the eight supported brokers, Tradewink adds Claude-based trading without asking you to move your money.
How does the Tradewink MCP server compare to Public.com's MCP server?
Public.com's MCP server is narrow and deep: Claude Desktop talks to one broker (Public) with trade-focused tools. Tradewink's MCP server is wide and deep: Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and ChatGPT Codex can all talk to any of eight brokers, with the same natural-language tools plus multi-agent research, a trade journal, and autonomous strategies.
Does Public.com support Cursor or VS Code?
Public.com's MCP setup guides currently document Claude Desktop only. Tradewink's @tradewink/mcp bridge works with any MCP-compatible client including Claude Desktop, Claude Code, Cursor, VS Code Copilot, Windsurf, Cline, and ChatGPT Codex. The same OAuth flow covers every client.
Is Public.com good for day trading?
Public.com is commission-free and supports stocks, ETFs, options, and crypto, but it's positioned as a long-term investing platform — reviewers have flagged the options chain as lacking depth for active traders. If you day-trade seriously, most traders keep an execution-focused broker (Alpaca, Tradier, IBKR) and use Tradewink for AI signals on top. You're not locked into a single broker.
Which is cheaper: Tradewink or Public.com?
Both have a free tier. Public.com makes money through payment for order flow on options, interest on cash, and a paid Public Premium tier. Tradewink is a subscription — the MCP server is free, and paid tiers add higher-capability AI models, autonomous strategies, and priority broker routing. You bring your own broker, so commissions depend on whichever you connect.
Can I use both together?
Yes. Tradewink does not currently list Public.com as a supported broker, so you can't route Tradewink orders to Public. But nothing stops you from running Public's MCP server and Tradewink's MCP server side-by-side in Claude Desktop — the AI will see both sets of tools. In practice most users pick one based on their primary broker.
