Parameters from the server's own tool schema.
This is a pure data extraction/parsing utility. It reads text input, identifies URLs within it, and returns the results—no side effects, no state changes, no external operations triggered. Belongs clearly in the Read category with low severity since misuse poses minimal risk (an agent could only extract URLs from text it has access to).
From the tool's definition Tool name 'text_extract_urls' and description 'Extract all URLs from a text' indicate a retrieval operation that parses input text and returns URLs without modifying data or triggering external actions.
