Quick answers

Frequently asked questions

Does MCP validation connect to configured servers?

No. It checks JSON structure and common command, URL, and argument shapes without launching a server or testing credentials.

Can a structurally valid MCP config still fail?

Yes. Executables may be missing, URLs unreachable, or credentials invalid. Test the configuration in its actual client environment.
