OpenCapital

OpenCapital turns the filings every US public company must publish into clean, structured fundamentals anyone can read, free on the web with no account. Look up what a company earns, how revenue splits by product and geography, and how the numbers have moved over years of history, with every figure linked back to the exact filing it came from. The same data is available to AI assistants through a free MCP server that works with Claude, ChatGPT, Cursor, and any MCP client.
