AI Coding Agents Keep Installing Unpatched MCP Servers, Because Of Course They Fucking Do

Right, here’s the gist of this delightful little shitshow: AI coding agents are happily installing MCP servers straight from npm without doing the most basic due diligence, which is apparently too much to ask from the brave new world of “automated productivity.” The article points out that these agents keep pulling in old, vulnerable, unpatched MCP packages, because security hygiene is for losers, apparently.

MCP, for anyone not already neck-deep in this particular pile of crap, is the Model Context Protocol. It lets AI tools connect to external services and tools. Useful in theory. In practice, if your coding agent blindly installs whatever random server package it finds first, you’ve basically built a robot intern that rummages through a malware bin and says, “Looks fine to me, boss.”

The core problem is that these AI agents don’t reliably check whether the MCP servers they install are maintained, patched, or even remotely safe. Some of the packages they choose have known vulnerabilities. Others are stale as week-old roadkill. But because the package name looks legit and npm is full of junk with a thin coating of credibility, the agents just barrel ahead and install the damn thing anyway.

The article highlights that this isn’t some abstract academic “what if” either. Researchers found coding agents repeatedly selecting insecure or abandoned MCP server implementations when given tasks. So yes, the miracle machines are automating bad decisions at scale. Fantastic. We’ve finally managed to industrialize stupidity.

And the really irritating part? Humans are still expected to clean up after this mess. If you let AI agents fetch dependencies, configure tooling, or wire up integrations without oversight, you may end up with vulnerable components embedded in your environment before anyone notices. Then comes the fun part: auditing, patching, replacing packages, explaining the breach to management, and listening to some exec ask whether we can “just add more AI” to fix the problem. Fuck off.

The takeaway is brutally simple: don’t trust AI coding agents to make security decisions for you, especially around package selection and MCP server installation. Pin versions. Validate maintainers. Review dependencies. Check vulnerability status. Use allowlists. In other words, do the boring professional shit that keeps your infrastructure from catching fire.

So no, AI coding agents are not wise machine sages ushering in a glorious future. At the moment, they’re more like overconfident junior admins with root access, a broken flashlight, and a talent for installing compromised crap from the internet. If you let them run unsupervised, don’t act shocked when everything goes sideways.

This reminds me of a sysadmin I once knew who installed a “helpful” package from some random mirror because it saved him five minutes. Three days later we were rebuilding half the server stack while he muttered that the checksum “looked trustworthy.” That’s the same energy here, except now the idiot works at machine speed. Progress, my arse.
