What is the Installed MCP Server?

MCP server that grounds coding agents on the dependency versions ACTUALLY installed in the current project — read from the lockfile and node_modules — so they stop

What the server does

An MCP server that tells Claude, Cursor, and any MCP client the exact version of each dependency installed in the current project — read from node_modules and the lockfile, fully offline. Studies put AI-generated deprecated-API usage at 25–38%; the root cause is that the model doesn't know which version is on disk. This fixes that.
