ShareSeer MCP Server is a Model Context Protocol (MCP) server that exposes ShareSeer's comprehensive SEC filings, insider transactions, and financial data to Claude and other MCP-compatible AI assistants. Hosted remotely by ShareSeer, it offers a simple integration URL (https://shareseer.com/mcp?api_key=YOUR_API_KEY_HERE) and an API key workflow (keys start with sk-shareseer-). Available tools include: get_company_filings (recent filings for a specific company), get_insider_transactions (insider trading transactions for a company), get_recent_filings (recent SEC filings across all companies), get_recent_insider_activity (recent insider activity), get_largest_daily_transactions (largest daily insider transactions), and get_largest_weekly_transactions (largest weekly insider transactions). The service provides Free and Premium tiers with distinct rate limits, data history (6 months vs 10 years), access to company data (basic vs all features), insider transactions (limited vs unlimited), largest transactions (current week vs historical), pagination (not on Free, enabled on Premium), and support via community or email. Remote MCP setup is recommended for up-to-date access with no installation.
