Beyond the supported languages

Even if your language or package manager is not in the table above, you can still query the Meterian vulnerability database through the MCP server by asking your AI assistant directly.

For example, if you are working on a Swift project using the Swift Package Manager, you can ask your AI assistant to fix a vulnerable dependency autonomously:

"Check if the ArgumentParser package in my Package.swift is vulnerable, get the next safe version using the Meterian MCP server, and update the file with the safe version."

Your AI assistant will query the Meterian vulnerability database, identify the safe version, and apply the fix directly — no IDE-level manifest support required.
