MCP.Pizza Chef: OctagonAI

Investors and analysts can ask ordinary questions about a company and get answers drawn from annual and quarterly filings, earnings call transcripts, share and crypto prices, ownership records, and prediction-market activity, each pointing back to where it came from. Four research abilities do the digging, and four more read Octagon's own help pages, which work even before you add a key. It only reads: it cannot trade, move money, or change anything anywhere.

octagon-mcp-server FAQ

Do I need a key?
Yes for the research tools, and signing up at Octagon is free. The four help-page tools work without one, so you can install first and add the key later.
What happens if I forget the key?
Nothing breaks. The server still starts, the help-page tools keep working, and the research tools simply answer with a setup error instead of failing silently.
Can I use this to research a stock before investing?
Yes — ask about filings, earnings calls, financials, ownership, or recent news, and the answers come back with the sources they were drawn from.
Can it place a trade or move my money?
No. It reads and reports only. There is no ability here to buy, sell, or touch a brokerage or wallet of any kind.
Does my question leave my computer?
Yes. Research questions go to Octagon's own service to be answered. The help-page tools fetch only from Octagon's public documentation site and do not carry your key.
How many things can it do?
Eight. Four research abilities covering market intelligence, deep research, prediction markets, and prediction-market history, plus four that read Octagon's documentation.
How hard is the setup?
You paste a short block into Claude Desktop or Cursor with your key inside it. Node has to be installed first. There is also a one-line install through Smithery.
Which apps does it work in?
Claude Desktop and Cursor are documented, and it also ships as a Claude plugin. Any app that can launch a local tool should work.
