InsiderRadar MCP

An official MCP server providing six read-only tools for accessing insider trading data, including SEC Form 4 filings, European register transactions, US Congress trades, 13F holdings, and lobbying data. It allows agents to query transactions, get summaries per company or insider, and retrieve lists of companies with significant insider buying or selling activity.
