# Silicon Floor

**Who owns AI stocks, who's buying, who's selling — every answer sourced.**
The research terminal for your AI agent: who owns AI and semiconductor stocks, what insiders and funds buy and sell,
financials as filed, short interest, dividends and the sector's market cap, with every SEC figure linked to its
filing. Free, no account, no API key.

This repository holds what you need to plug Silicon Floor into an assistant: the connector settings, a Claude Code
plugin, a GitHub Copilot CLI plugin, a Gemini CLI extension and a research skill. The server itself runs at
`https://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 by
  quarter: 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, the
  most 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, against
  SMH. 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, and
  each 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, and the short float on a float counted from
  SEC filings, every holder taken out named.
- **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 as
missing, never guessed.

## Connect

**Claude** (web, desktop, mobile): Silicon Floor is in Claude's
[connector directory](https://claude.ai/directory/silicon-floor). Or add it yourself: Customize → Connectors → + →
Add custom connector, name it Silicon Floor, paste `https://siliconfloor.com/mcp`.

**Claude Code**, as a plugin (server and research skill):

```
/plugin marketplace add Baptoshi/silicon-floor
/plugin install silicon-floor@siliconfloor
```

or the server alone:

```
claude mcp add --transport http siliconfloor https://siliconfloor.com/mcp
```

**GitHub Copilot CLI**, as a plugin (server and research skill):

```
copilot plugin marketplace add Baptoshi/silicon-floor
copilot plugin install silicon-floor@siliconfloor
```

**Gemini CLI**:

```
gemini extensions install https://github.com/Baptoshi/silicon-floor
```

**The research skill alone**, for any agent that supports [Agent Skills](https://agentskills.io), via
[skills.sh](https://skills.sh). It uses the MCP server, so add the server to the same client too:

```
npx skills add Baptoshi/silicon-floor
```

**ChatGPT**: turn on developer mode in Settings (Security and login), then open Plugins, click +, name it
Silicon Floor and enter `https://siliconfloor.com/mcp` as a public endpoint.

**Cursor** (`~/.cursor/mcp.json`):

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

**VS Code** (`.vscode/mcp.json`):

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

**A client that only runs commands**, through the bridge on npm — it forwards stdio to the same hosted server,
nothing is installed and no key is needed:

```json
{
  "mcpServers": {
    "siliconfloor": { "command": "npx", "args": ["-y", "siliconfloor-mcp"] }
  }
}
```

Any other MCP client: Streamable HTTP at `https://siliconfloor.com/mcp`, no authentication. Also listed in the
[official MCP Registry](https://registry.modelcontextprotocol.io) as `com.siliconfloor/silicon-floor`.
