extract_features
AI agents call extract_features 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.
Feature extraction is a standard computer vision operation that analyzes image properties (color, texture, shape) without modifying or deleting data. It falls squarely into the Read category.
From the tool's definition Tool named 'extract_features' on an image analysis server with sibling tools like 'analyze_image', 'check_image_quality', 'list_features', and 'get_dominant_colors'.
Attacks that exploit this kind of access
extract_features. 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 extract_features: 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.
extract_features 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 extract_features 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 extract_features. 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.
extract_features 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.
extract_features is one line of Imagefeatures's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
