Why is the cmd /c wrapper necessary on Windows?

On Windows systems, running NPX commands directly often leads to 'Connection closed' errors; wrapping the command in 'cmd /c' ensures the proper execution environment for MCP servers.

Does this skill support project-specific configurations?

Yes, it manages both global (~/.claude.json) and project-level (.mcp.json) configurations, where project settings automatically override global ones for the same server.

Can I manage Python-based MCP servers with this skill?

Absolutely. It includes templates and support for Python-m modules, Node.js scripts, and direct execution, in addition to NPX-based tools.

How do I verify if my MCP configuration is valid?

The skill provides a list command to view active servers and includes syntax checking utilities to validate your JSON configuration files before restarting.
