// WHEN AI AGENTS USE THIS TOOL

AI agents invoke il_histogram_build_mean_std_dev to trigger processes or run actions in Leaper Vision Toolkit. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.

// WHY ENFORCE A POLICY ON IL_HISTOGRAM_BUILD_MEAN_STD_DEV

il_histogram_build_mean_std_dev can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. Intercept enforces rate limits and validates arguments to keep execution within safe bounds.

// RECOMMENDED POLICY

Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

What does the il_histogram_build_mean_std_dev tool do? +

Build histogram from input image and region, calculate mean and standard deviation. Calculate the mean and standard deviation of the histogram. The histogram collects count of data in provided image into a set of predefined bins. 基于输入图像和区域，生成直方图，计算直方图的均值和标准差。工具不需要通过其它工具设置参数，不需要传入ILHistogram的对象。 Returns a serialized JSON with MeanValue and StdDevValue properties.. It is categorised as a Execute tool in the Leaper Vision Toolkit MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on il_histogram_build_mean_std_dev? +

Add a rule in your Intercept YAML policy under the tools section for il_histogram_build_mean_std_dev. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Leaper Vision Toolkit MCP server.

What risk level is il_histogram_build_mean_std_dev? +

il_histogram_build_mean_std_dev is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit il_histogram_build_mean_std_dev? +

Yes. Add a rate_limit block to the il_histogram_build_mean_std_dev rule in your Intercept 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.

How do I block il_histogram_build_mean_std_dev completely? +

Set action: deny in the Intercept policy for il_histogram_build_mean_std_dev. 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.

What MCP server provides il_histogram_build_mean_std_dev? +

il_histogram_build_mean_std_dev is provided by the Leaper Vision Toolkit MCP server (leaper-mcp/leaper-mcp-proxy). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
