Twitter Signal MCP runs on your own machine — the client starts it, so there is no endpoint to ping. 54 installs a week from npm. Last commit 6 Oct 2026.
Live X/Twitter search, profiles, leads, pain points, bot checks, AI digests. Paid per call, x402.
Today is the operative word: we check Twitter Signal MCP every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
