Part of the Leaper Vision Toolkit MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call image_stats_count_pixel_color to retrieve information from Leaper Vision Toolkit without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though image_stats_count_pixel_color only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Count the pixels in the input image which is between or outside the given color bounds. For all of the channels, the pixel value is within the color bounds, then it's a "between" color pixel. Otherwise, for any of the channel, the pixel value is smaller or greater than the lower/upper bound, then it's a "outside" color pixel. 计算输入彩色图像中像素值在设置范围之内、之外的像素总数。 对于每一个像素，若其所有通道的颜色值均在指定范围内，则该像素为范围内"between"像素。 反之，若其任一通道的数值小于或大于指定颜色范围的下限或上限，则该像素为范围外"outside"像素。 Returns a JSON string with the following fields: BetweenCount: The count of pixels within the bounds OutsideCount: The count of pixels out of the bounds 返回结构是一个序列化的JSON字符串，包含以下字段： BetweenCount: 颜色值在颜色范围之间的像素总数 OutsideCount: 颜色值在颜色范围以外的像素总数. It is categorised as a Read tool in the Leaper Vision Toolkit MCP Server, which means it retrieves data without modifying state.
Add a rule in your Intercept YAML policy under the tools section for image_stats_count_pixel_color. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Leaper Vision Toolkit MCP server.
image_stats_count_pixel_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 image_stats_count_pixel_color 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.
Set action: deny in the Intercept policy for image_stats_count_pixel_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.
image_stats_count_pixel_color 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.
