Security

The server binds to localhost only and requires no authentication, so any local process can reach it on the configured port. It exposes powerful capabilities — running builds/tests, executing immediate-window expressions with side effects (immediate_execute), and driving the debugger — against your open solution. Only enable it on machines you trust, and disable tool groups you do not need in MCP Server Settings.
