Octagon
By thumbsupordown
Octagon's MCP server does investment research across public and private markets with source-backed answers: SEC filings including 10-K, 10-Q, 8-K, 20-F and S-1 for over 8,000 public companies, earnings call transcripts and management commentary, financial metrics and ratios, stock and crypto market data, over 3 million private companies with funding rounds and investors, M&A and IPO transactions, and prediction markets. Citations are the point for this category — it includes a deep-research agent that synthesises across sources rather than returning one lookup.
