AI agents call pinchtab_cookies to retrieve information from Pinchtab without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves cookie data from the browser without modifying, deleting, or executing any operations. It is a read-only query of existing browser state. The severity is low because while cookies may contain session tokens or user identifiers, merely reading them does not directly compromise systems—the impact depends entirely on how an agent uses the retrieved data.
From the tool's definition Tool name 'pinchtab_cookies' and description 'Get all cookies for the current page' indicates a retrieval operation with no side effects.
