Signals

com.datahyena/signals

If you're building sales intelligence, lead gen, or market research workflows and need structured deal flow without scraping Crunchbase, this gives you five read tools over Datahyena's API: funding rounds, acquisitions, exec moves, companies, and investors. Each tool maps to a REST endpoint with filters for round stage, amount, country, industry, and date range. Auth is OAuth 2.1 with PKCE, scoped per workspace. It runs on the same credit model as their API, one credit per record returned, and works across Claude, Cursor, and any MCP client via streamable HTTP. Good for prompts like "Series A fintech rounds in the last week over $10M" without leaving your editor.
