Silicon Floor MCP¶

Remote MCP server (Streamable HTTP, no account, no key) - the AI and semiconductor stock terminal, opened to agents.

Why This Matters for Operators¶

Anyone selling to, buying from, investing in or competing with the AI economy eventually needs the numbers behind the companies in it: who owns NVIDIA, what Broadcom's margins are doing, which funds are buying, what founders and directors are selling, whether Microchip's cash covers its dividend. That research normally means tab-hopping between filings, fund trackers and finance sites, each with its own freshness clock.

Every answer arrives with its source and its data date, and the tools distinguish what is filed from what is inferred. Ownership is reported as a range because two managers can report the same shares; a holder that falls below 5% stops reporting and that is not a sale; a person has one figure on Form 4 and another on Schedule 13D/G. The server says which one it is quoting - exactly the discipline a business conversation needs when someone asks "how much does Musk actually own".

The tool set is deep where it matters: screen_companies filters by growth, margins, valuation, size and trend; get_figure_history shows one number over time with restatements flagged; get_fund_flows reads what hedge funds and institutions did each quarter; what_changed answers "what happened since a date". Sources include SEC XBRL filings, Forms 13F, 13D/G and 3/4/5, Form N-PORT fund holdings, FINRA short interest and second-by-second prices while markets are open.

Nothing personal is requested: calls are counted by tool and by day, no IP address and no conversation content. A JSON API mirror lives at siliconfloor.com/api/v1/schema.

Business Relevance¶

Founders and executives read the public comparables around them - margins, growth, ownership - without a terminal subscription.
Sales and BD teams prep account conversations with current, sourced numbers about their prospects' public peers.
Investors and analysts screen the sector, track insider and fund moves, and cite the filing behind each figure.
Content and IR teams check a number and its date before it goes into anything public.

Integration with CorpusIQ¶

CorpusIQ stays inside the business: Stripe, QuickBooks, Shopify and GA4 answer what is actually happening in the operator's own numbers. Silicon Floor covers the listed world around it - the suppliers, customers, competitors and partners that show up in those same conversations. Composed, an operator can line their own growth and margins against the public market's, with both halves sourced and date-stamped.

Limitations¶

Sector-only: 200+ AI-economy names, not the whole market.
Read-only research, not investment advice; nothing here trades.
Free and rate-limited to stay fast for everyone.
Headlines are third-party text returned as data.
Ownership history starts at the end of 2019; some fields are simply unavailable (nulls, not estimates).

FAQ¶

Where does the data come from?¶

SEC filings for financials and ownership (XBRL, 13F, 13D/G, Forms 3/4/5, N-PORT), FINRA for short interest, and live prices while US markets are open. Every figure carries the date behind it.

Does it cost anything or need an account?¶

No. The server is free, asks for nothing personal and only reads.

Why is ownership shown as a range?¶

Two managers can report the same shares, so the data comes as a range on purpose. The tools also explain when a holder dropping below 5% stops reporting, which is not a sale.

Can the agent take actions?¶

No. All eighteen tools are read-only research.
