FileSystem MCP Server
Built for Visual Studio 2022 workflows, this server gives Claude controlled filesystem access through a clean set of read and write operations. It exposes tools for listing directories, reading files, and writing content, all constrained by configurable allow lists for both paths and file extensions. Write access is opt-in and disabled by default. The hybrid config approach is clever: use command line args in your MCP JSON for production, or drop a config.json next to the binary for local debugging without arguments. Cross-platform path handling works automatically. Reach for this when you need Claude to read project files, generate code to disk, or navigate a folder structure without giving it your entire filesystem.
