Find contours after thresholding. Optionally draw them onto output_path.
AI agents call find_contours to retrieve information from farshid-mcp-imageProcessing without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Contour finding is a computer vision analysis operation that extracts and returns feature information from an image. While it can produce output visualization, this is a deterministic, reversible operation that does not create, modify, delete, or execute arbitrary external operations. It fits the Read category as a tool that retrieves/queries image features without side effects.
From the tool's definition Tool performs image analysis via contour detection (find_contours) and optionally renders visual output. The description 'Find contours after thresholding.
Attacks that exploit this kind of access
Find contours after thresholding. Optionally draw them onto output_path. It is categorised as a Read tool in the farshid-mcp-imageProcessing MCP Server, which means it retrieves data without modifying state.
Register the farshid-mcp-imageProcessing MCP server in PolicyLayer and add a rule for find_contours: 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 farshid-mcp-imageProcessing. Nothing to install.
find_contours 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 find_contours 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 find_contours. 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.
find_contours is provided by the farshid-mcp-imageProcessing MCP server (pirahansiah/farshid-mcp-imageprocessing). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
