Connect your AI to OpenCapital
Bring OpenCapital's fundamentals into Claude, ChatGPT, Codex, and Cursor over MCP, and ask questions in plain English.
OpenCapital now speaks MCP, the open protocol for connecting tools to AI assistants. Link your account once and the fundamentals you research here become available inside Claude, ChatGPT, Codex, and Cursor.
Ask for a company's margins over the last ten years, screen for businesses on your own criteria, or pull a peer comparison, and get an answer grounded in the same filing-derived data the site runs on, with sources you can check.
Why it matters
Your assistant stops guessing from memory and starts working from the filings. The free tier covers everyday research; heavier use is unmetered on the paid plan.
