Xflux MCP Server
Xflux runs on your own machine — the client starts it, so there is no endpoint to ping. 52 installs a week from npm. Last commit 5 Nov 2026.
X/Twitter read API for agents: search, timelines, Smart Money. Claude/Cursor MCP. Not for posting.
What the code does
We read the source, 3 d ago · rules 995398eba69f
Found in continuous integration, deployment or infrastructure files, or in a neighbouring package of the same monorepo. None of this is installed when you add the server: it describes how the project is built and released. We list it because a leaked key in a build pipeline is still a real problem, but it is not something this server does on your machine.
return u.hostname.toLowerCase() === "hooks.slack.com" && u.pathname.startsWith("/services/");
Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.
Nothing serious here today
Today is the operative word: we check Xflux every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
