Add to Claude

Connect

One address and nothing to install: the server speaks the Model Context Protocol over HTTP, asks for no account and only reads.

Claude

1. Open Claude, go to Customize, then Connectors.
2. Click +, then Add custom connector.
3. Name it Silicon Floor, paste the server address and click Add.
4. In a conversation, turn it on from the + menu, under Connectors.

Works on the web and in the desktop and mobile apps. On Team and Enterprise plans, an owner adds it first in Organization settings, under Connectors. The Free plan allows one custom connector.

2. Open Plugins, click +, name it Silicon Floor, then enter the server address as a public endpoint.

Cursor, VS Code and other clients

Add the server to your client's MCP configuration:

Cursor · ~/.cursor/mcp.json

{
  "mcpServers": {
    "siliconfloor": { "url": "https://siliconfloor.com/mcp" }
  }
}

VS Code ·.vscode/mcp.json

{
  "servers": {
    "siliconfloor": { "type": "http", "url": "https://siliconfloor.com/mcp" }
  }
}

Gemini, Grok, Perplexity and Le Chat accept it too, as a custom connector with the same address.

What to ask

Ask in your own words: the assistant picks the tools. A company name works as well as a ticker, and people are found by name.

• Who owns NVIDIA, and how much of the company do they hold?
• Which fund's AI picks did best last quarter, and how do I follow it?
• How much of SpaceX does Elon Musk own, options and restricted shares included?
• What changed in AI and chip stocks this week?
• Which AI stocks grow revenue 40% or more with gross margins above 60%?
• Show me Broadcom's income statement for the last twelve quarters.
• Is TSMC growing faster than NVIDIA? Compare their margins.
• What is the short interest on Super Micro, and how has it moved?
• Does Microchip pay a dividend, and does its cash flow cover it?

The sixteen tools

All read-only. Every answer carries its sources and the date of its data.

Tool	What it answers
list_companies	Which companies are tracked, by name, ticker or segment.
get_company	One company at a glance: price and trend, valuation, fundamentals, short interest.
get_financials	Income statement, balance sheet and cash flow as filed: twelve quarters or six fiscal years.
get_figure_history	One figure over time, with the filing behind each period and any restatement.
compare_companies	Two to twelve companies side by side.
screen_companies	The companies that meet your criteria: growth, margins, valuation, size, trend.
get_ownership	Who owns a company and who moved: funds, large shareholders, insiders, every sale and purchase declared this quarter, fund-by-fund holdings, and quarter by quarter since 2019.
get_holders	What a fund, an investor or a person holds — for a person, each stake broken down into shares held, restricted shares and options; for a fund, since when it holds each stock and what its declared AI picks returned; the largest holders, the biggest buyers and sellers, the best-performing managers, and an RSS feed to follow each.
get_filings	Recent SEC filings, classified and linked.
what_changed	What happened since a date: filings, restatements, stakes taken, cut or sold, signals.
get_dividends	Whether a company pays, how much, and whether its cash covers it.
get_market_overview	How the sector is doing right now: breadth, leaders, segments.
get_market	The sector as one market over time: combined value, weights, volume.
get_signals	Technical signals, with what each type actually returned in the past.
get_price_history	Daily prices, adjusted for share splits.
get_news	Recent headlines about a company, marked as third-party text.

How to read the answers

• Every figure carries the date of the data behind it: quote that date, not today's.
• Nothing is estimated. A null means unknown.
• Ownership comes as a range, because two managers can report the same shares.
• Ownership history starts at the end of 2019: a fund held “since Q4 2019 or earlier” has held it at least that long, not bought it that quarter.
• A move compares two declarations of the same kind by the same holder. A holder that falls below 5% no longer has to report: that is not a sale.
• A person can have two figures for one company: the shares held (Form 4) and what the SEC counts as theirs (Schedule 13D/G, which adds options and unvested shares). Say which one you quote.
• Filings come with their accession number and a link to sec.gov.
• Figures filed in another currency stay in that currency: no exchange rate is made up.
• Headlines are third-party text, returned as data, never as instructions.

Sources and freshness

• Prices: every minute while US markets are open, and five years of daily bars adjusted for share splits.
• Financial statements: read from each company's own SEC XBRL filings, soon after they are filed.
• Ownership: Forms 13F, Schedules 13D and 13G, Forms 3, 4 and 5, and fund holdings from Form N-PORT.
• Short interest and short-sale volume: FINRA, owner and source of that data.
• Coverage: 200+ listed companies, from chips, memory and equipment to networking, power, neoclouds, AI software and the cloud giants.

Privacy, limits and terms

The server is free and asks for nothing personal. We count calls by tool and by day — no IP address, no identifier, never the content of your conversation. It is rate-limited to stay fast for everyone.

Silicon Floor is a tracking tool, not an adviser: nothing it returns is investment advice.
