max_results must be a positive integer

Error message

max_results must be a positive integer

What it means

Optional-field type guard in parse_search_args: "max_results" was provided but is not a positive integer usable as a result cap (wrong JSON type — string, float, negative, or zero). The faulting input is a max_results value that fails positive-integer validation.

Solutions

1. Pass max_results as a positive integer, e.g. 10.
2. Omit the field to use the tool's default cap.
3. Coerce string-typed numbers ("10") to integers before invoking.
