CEORater MCP Server

CEO performance data for AI agents, over the Model Context Protocol.

How the stock did over each CEO's tenure, what the S&P 500 did over that same window, how long they have been in the job, and what they were paid — for 500+ US public companies.

Free. No account, no API key, no signup.

Install

Needs Python 3.10 or newer.

Windows

pip install ceorater-mcp

macOS

brew install pipx
pipx install ceorater-mcp

Homebrew's Python refuses pip install into the system environment, so plain pip install fails there with externally-managed-environment.

Linux

sudo apt install pipx      # Debian, Ubuntu
sudo dnf install pipx      # Fedora, RHEL
pipx install ceorater-mcp

Connect it to Claude Desktop

Add this to your claude_desktop_config.json:

{
  "mcpServers": {
    "ceorater": {
      "command": "ceorater-mcp"
    }
  }
}

That file lives at:

macOS	~/Library/Application Support/Claude/claude_desktop_config.json
Windows	%APPDATA%\Claude\claude_desktop_config.json

Restart Claude Desktop. No env block and no key — that is the whole config.

Tools

Tool	What it does
ceo_lookup	One company by ticker. Always returns an array.
ceo_list	Every CEO, or filter by sector, industry, founder
ceo_search	Loose substring match across company, ticker, CEO, sector, industry
ceo_sectors	The 11 GICS sectors and their company counts
ceo_industries	GICS sub-industries, optionally within one sector
ceo_meta	Row count, field list, data freshness

Ask things like "Which founder-led tech CEOs beat the S&P 500 over their tenure?" — the agent can call ceo_list with sector="Information Technology" and founder=true and do the comparison itself.

The fields

Exactly the ten www.ceorater.com displays.

Field	Meaning
ticker	Exchange ticker
company	Registrant name as filed
ceo	Chief executive
founder	Whether this CEO founded the company
sector	GICS sector
industry	GICS sub-industry
tenure_years	Years in the role
total_return_pct	Total stock return across the tenure, as a percentage
spy_return_pct	The S&P 500 over that same period
compensation_musd	Reported compensation, in millions of USD

Returns are already percentages: 545800 means +545,800%. Nothing to convert.

Sectors and industries are S&P's own GICS values, matched company by company on SEC CIK rather than ticker, because tickers get reassigned and CIKs do not. Eleven sectors, 128 sub-industries.

Co-CEOs get a record each. Oracle, KKR, Globe Life, Lululemon and Netflix each return two people with their own start dates and returns, which is why ceo_lookup always returns a list.

Upgrading from 0.x

Version 0.x required a CEORATER_API_KEY and called a paid API that no longer exists — every tool in it fails. Version 1.0 needs no key and is not configurable; remove any CEORATER_API_KEY from your MCP config.

The scores are gone. CEORaterScore, AlphaScore, CompScore and RevenueCAGRScore have been retired from the product, along with Avg Annual TSR, which was computed as total return divided by tenure rather than compounded and overstated every multi-year record. What remains is reported figures only.

Running it as a remote server

MCP_TRANSPORT=http PORT=8080 ceorater-mcp

Serves streamable HTTP, stateless, so it sits behind Cloud Run or similar without session affinity. No per-user credentials to manage.

---

The underlying API

The server is a thin client over a public HTTP API you can call directly:

curl -s https://api.ceorater.com/api/v1/ceo/NVDA

Documented at https://www.ceorater.com/api-docs.html Rate limit 100 requests per 15 minutes per IP.

CEORater publishes reported figures and makes no investment recommendations.
