Hey Product Hunt. We are RockFlow. For months my own investing workflow had one stupid step in it that I never got around to fixing. I'd open Claude, then type out my positions by hand. Ticker, average price, and how big it was against everything else I hold. By the time the model had a usable picture of my account I'd usually forgotten the question I sat down to ask. Screenshots didn't help much either, since it would misread a number and then reason from it with total confidence. So we put the account behind an MCP endpoint. RockFlow MCP is hosted, so there's nothing to install and no API key to request. One line in Claude Code: claude mcp add --transport http rockflow Cursor, Codex, Claude web and Grok take the same endpoint through their add-custom-connector flow. You authorize in the browser with OAuth 2.1 and choose a paper or a live account at the consent screen. 17 tools land in your client. Quotes and charts, option expiry dates and full chains with greeks, IV and open interest, positions, assets, orders, watchlist, and stock and option order placement. Things people have been asking it: "What's my biggest single-name concentration, and what changes if I trim it by a third?" "Find short puts on NVDA expiring within 30 days, show me premium, annualized yield and the breakeven." "Pull my open orders and flag the ones that look stale against where the stock is trading now." Paper accounts are free, get created automatically when you authorize, and need only a RockFlow ID. No brokerage account or application needed. The MCP service itself is free right now. Authorization is currently all or nothing, so a live account hands the model order placement alongside everything else. There's no read-only scope yet. Splitting those is next on the roadmap, and until then I'd stay on paper. We also make Bobby AI, our own investing assistant. This endpoint exists for the people who'd sooner stay in the client they already have open. What's the first thing you'd ask an AI that could see your whole portfolio? I'm collecting answers to decide which tools to build next.
