When does this happen?

IF Drive letter duplication in credential file path (C:\C:\) when authenticating Google Drive MCP server on Windows.

How others solved it

THEN Avoid using fileURLToPath(import.meta.url) with path.join if the result is already absolute. Use path.resolve() to ensure a single drive letter, or extract the directory path once and join only relative components. As a workaround, manually create the credentials file at the correct path (removing duplicate drive letter).
