sort_by_color
AI agents call sort_by_color to retrieve information from Imagefeatures without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves and organizes image data based on color properties. While the description is empty, the naming pattern and server context (classic computer vision feature extraction) indicate this is a query/retrieval operation with no side effects. Sorting is a non-destructive, read-only operation that does not create, modify, or delete underlying data.
From the tool's definition Tool is part of an image feature extraction server; sibling tools like 'analyze_image', 'extract_features', 'get_dominant_colors', and 'compare_images' all perform read-only analysis.
Attacks that exploit this kind of access
sort_by_color. It is categorised as a Read tool in the Imagefeatures MCP Server, which means it retrieves data without modifying state.
Register the Imagefeatures MCP server in PolicyLayer and add a rule for sort_by_color: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Imagefeatures. Nothing to install.
sort_by_color is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the sort_by_color rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for sort_by_color. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
sort_by_color is provided by the Imagefeatures MCP server (kelkalot/imagefeatures-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
