WHAT IT DOES

What overlay does on 🪄 ImageSorcery MCP

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

RISK

Why overlay is rated Medium

The name 'overlay' strongly implies combining or layering images, which is a Write operation (modifies image data). The description is empty, so confidence is low. Given the sibling tools all perform image manipulation (Write-level operations), this tool almost certainly modifies an image by overlaying content onto it.

From the tool's definition Tool name 'overlay' and empty description. Based on naming convention and sibling tools (blur, change_color, crop, draw_arrows, draw_circles, draw_lines, draw_rectangles, draw_texts), this tool likely composites or layers one image over another.

RECOMMENDED RULE

The rule that runs overlay safely

PolicyLayer is an MCP gateway: it sits between your AI agents and 🪄 ImageSorcery MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For overlay, this is the rule to start with:

overlay Rate-limited

overlay stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
