Whetstone MCP runs on your own machine — the client starts it, so there is no endpoint to ping. 39 installs a week from npm. Last commit 17 Jun 2026.
U.S. public-records: business registration (KYB), filings, watchlist screening, federal awards.
Today is the operative word: we check Whetstone MCP every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.
