This repository holds what you need to plug Silicon Floor into an assistant: the connector settings, a Claude Codeplugin, a GitHub Copilot CLI plugin, a Gemini CLI extension and a research skill. The server itself runs athttps://siliconfloor.com/mcp; its code is not in this repository.

What you can ask

• Who's buying, who's selling? Funds, insiders and big shareholders, from their own 13F, 13D/G and Form 4 filings.
• What did insiders sell this quarter? CEO, founder and director sales and purchases across the sector, quarter byquarter: the biggest sellers and buyers, what they still hold, and the filing behind each.
• What did hedge funds buy last quarter? Each quarter's 13F filings, read in full: where the money went by sector, themost bought and sold stocks, the biggest moves of named funds.
• What does the CEO really own? Shares, restricted stock and options, broken down filing by filing.
• Whose AI picks did best? Funds ranked on what the AI stocks in their 13F returned, quarter after quarter, againstSMH. Then follow one: every fund and big shareholder has an RSS feed of their filings.
• How big is the AI trade? The market cap of the whole sector, split between chips, cloud, power and the rest, andeach company's weight in it, day by day.
• Which ones pay a dividend? Yield, growth, and how well each payout is covered.
• Is it really growing? Revenue, margins and cash flow exactly as filed: 12 quarters or 6 years.
• Is it cheap or expensive? Companies side by side, or the whole sector screened on growth, margins and valuation.
• Are short sellers piling in? FINRA short interest, every two weeks.
• What's the news? The latest AI headlines, tagged by company.
• What changed this week? Earnings, insider buys, new 5% stakes, restatements, ranked by what matters.

Every number carries its date and its source, and SEC figures link to the filing itself. Missing data shows up asmissing, never guessed.
