When running the MCP server, I'm getting the following error:

  throw new ERR_MODULE_NOT_FOUND(packageName, fileURLToPath(base), null);
        ^

Hello Bruno Quaresma (@BrunoQuaresma), thanks for raising this. It looks like this is an upstream dependency bug that was introduced in the last 2 hours in xml-fast-parser. Looks like someone accidentally pushed a change to link to a file system dependency.

the package authors are aware of it and working on a fix, once that is resolved we can publish a fixed version. As a temporary workaround, as mentioned here, you can manually install fast-xml-builder to your own machine, locally or globablly.
