Signal8 provides read-only SEC-filing intelligence and market data for US-listed companies, plus US congressional & executive-branch (STOCK Act) trading and FEC campaign-finance data — all through a single MCP connector.
Resolve any company by name or ticker, then pull real-time quotes, fundamentals, earnings, analyst estimates, dilution-risk scoring, short interest, and float. Read SEC filings and exhibits straight from EDGAR (10-K/10-Q/8-K/S-1, full text + search). Track insider activity from Form 4 (individual trades, cluster buys, cross-company patterns) and institutional ownership from 13F filings (holders, position changes, top-AUM funds).
On the political side, surface what members of Congress and Cabinet officials are trading (STOCK Act disclosures), reverse-lookup a ticker to see which politicians traded it, follow campaign donors and PAC money via OpenFEC, and watch upcoming legislative and executive-order catalysts with the sectors and tickers they affect.
Every response is grounded in primary sources (SEC EDGAR, OpenFEC, exchange market data) — no speculation. Tools are metered by the caller's API-key tier. Sign in with OAuth; Signal8 mints a dedicated, revocable per-connection credential and never asks you to paste a raw key.
