Regulatory Filings MCP — SEC, 13F, Form 4 & Activist Filings

An MCP server that gives any AI agent — Claude, Cursor, Cline, Windsurf, n8n — 17 SEC and institutional-filing tools through one connection: Form 4 insider trades, 8-K material events, 13F institutional holdings, Schedule 13D activist stakes, and Form D private raises, plus derived signals like insider-cluster detection, 13F position deltas, sovereign-wealth-fund holdings, and IPO/earnings calendars. Pay per tool call, no seats, no $24K terminal — wire SEC filing intelligence straight into your agent.

Each tool runs the underlying nexgendata SEC scraper on demand, so coverage and freshness depend on the delegated actor. Comparative framing against WhaleWisdom, 8-K Push, PitchBook, or a Bloomberg seat is workflow-level — verify coverage per tool for your specific use case.
