FilingSpy is a product from FilingSpy LLC that tracks SEC filings and superinvestor portfolios, surfacing quarterly 13F changes, insider trades, and as-filed financials for US-listed securities. It publishes daily digests of filings worth a look, a tracked-investor consensus view, an insider screener, a 13F season tracker, and a Graham-style "cigar butts" screen, and ships an MCP server with an agent SKILL so AI agents can query SEC filing data directly.
