Hi @biohazardxxx, thanks for reporting this!

The issue was that we were using process.env.HOME to resolve paths, which is undefined on Windows (Windows uses USERPROFILE instead).

This has been fixed in commit c0dfc67 by replacing all process.env.HOME references with os.homedir() from Node.js, which works cross-platform (Linux, macOS, Windows).

Files fixed:

• src/ssh-key-manager.js — known_hosts path resolution
• src/index.js — SSH key path resolution
• src/ssh-manager.js — SSH key path resolution

Please update to the latest version and let us know if it works:

npm update -g mcp-ssh-manager

If you installed from source, just git pull and restart Claude Code.
