tar extraction is missing the archive file flag; tar xz mcp-publisher won’t read from stdin on Ubuntu’s GNU tar and will fail the install step. Use tar -xzf - mcp-publisher (or equivalent) when piping from curl.

The packageArguments[0] declares format: "number" but the default value is a JSON string ("6006"). This is likely to fail schema validation or be mis-typed by tooling; use a numeric default (6006) if the schema expects a number.

Suggested change
