AI agents call text_count_occurrences to retrieve information from UnClick without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameters from the server's own tool schema.
The tool performs a read-only text search operation that returns a count. It has no side effects, does not execute code, does not modify data, and does not access external systems or financial resources. The blast radius of misuse is minimal—an agent could only learn information about text content that was already provided to it.
From the tool's definition Tool description: 'Count occurrences of a substring in text.' This is a query/analysis operation that retrieves information about text content without modifying, executing, or deleting anything.
