+      # This was reported to yargs-parser as well -
+      # https://github.com/yargs/yargs-parser/issues/517 and we already tried
+      # their suggestion about disabling the meta resolution in webpack,
+      # alongside others (dependency overrides, disabling the bundling of
+      # yargs-parser), and none of the solutions yield a working extension. So
+      # until we figure out a fix for this we need to keep mongodb-mcp-server
+      # working with v21 of yargs-parser.
