Clear all cached image analysis results.
AI agents call clear_image_cache to permanently remove resources in AI Image MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly deletes all cached image analysis results. While the underlying images and original data remain intact, the cached analysis results are permanently purged, requiring costly re-computation. The blast radius is medium because it affects performance and cached work product, but does not delete source images or primary data.
