WHAT IT DOES

What check_url_slug does on GoHighLevel MCP Server

AI agents call check_url_slug to retrieve information from GoHighLevel MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why check_url_slug is rated Low

This tool performs a lookup/query operation to verify whether a URL slug exists or is available. It does not create, modify, delete, execute code, or move money. It purely returns availability status information to inform subsequent actions. The blast radius of misuse is minimal—an agent could spam checks, but this causes no actual data modification or system harm.

From the tool's definition check_url_slug checks if a URL slug is available. The verb 'check' and the intent to verify availability before creation indicates a query operation with no side effects. It retrieves information about slug availability status.
