Pipeworx Sec Beneficial Ownership MCP

This MCP server provides tools to access and analyze SEC Schedule 13D and 13G filings, which disclose beneficial ownership of public companies. It allows agents to list recent filings, parse specific filing details such as reporting owners and voting power, and compare amendments against prior filings to track changes in ownership stakes.
