Json To Url Params

Data REST API MCP

Convert a JSON object into a URL query string that starts with "?". Arrays repeat the key (or use key[] notation), nested objects are JSON-stringified, null values are skipped, and values are URL-encoded by default.

This page documents the MCP tool findutils:json_to_url_params. See the REST reference →
