WHAT IT DOES

What set_reasoning_effort does on Screenshot Analyzer MCP

AI agents use set_reasoning_effort to create or update resources in Screenshot Analyzer MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Screenshot Analyzer MCP environment.

WHY IT NEEDS A POLICY

Why set_reasoning_effort needs a policy

This tool modifies a reversible configuration setting (reasoning effort level) for the analysis engine. It does not retrieve data (Read), execute arbitrary code (Execute), delete anything (Destructive), or move money (Financial). The change can be undone by setting a different effort level. Confidence is high because the purpose is clearly configuration management with predictable, non-destructive effects.

From the tool's definition Tool name 'set_reasoning_effort' and description 'Set the reasoning effort level for GPT-5.2' indicate modification of a configuration setting. The verb 'set' combined with 'reasoning effort level' denotes creating or updating a configuration parameter.
