Why Audit
Over a few months of using AI tools, you accumulate MCP servers. You added a database server for that one project. A file server for your main codebase. A web search server someone recommended. A Slack server you tried once. Before you know it, you've got eight servers connected, some of which you haven't used in weeks.
Each connected server is a potential access point. Even servers you aren't actively using still start with your AI client, consume resources, and have whatever permissions they were configured with. An audit is just taking ten minutes to review what's connected and whether it should be.
What to Check
Open your AI client's configuration file and go through each server entry. For each one, ask three questions: Am I still using this? Does it have appropriate permissions? Is it up to date?
Servers you're no longer using should be removed. There's no benefit to having them connected and some risk. A server for a project you finished three months ago is just unnecessary attack surface.
Permissions deserve scrutiny. That database server you configured with full read-write access because you needed to update one record six weeks ago, does it still need write access? Tightening permissions to match your current actual needs is one of the easiest security improvements you can make.
Version currency matters too. Run npm outdated or check the server's GitHub releases page. If you're several versions behind, you might be missing security patches and bug fixes.
A Simple Quarterly Cadence
Set a calendar reminder to audit your MCP servers once a quarter. It takes ten minutes and catches drift before it accumulates into a real problem. During the audit: remove servers you don't use, tighten permissions on servers you keep, update everything to current versions, and check security grades on Skillful.sh for any changes.
