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 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 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 below, between or above the given threshold bounds. 计算输入图像中灰度值在设置范围之下、之内、之上的像素总数。 Returns a JSON string with the following fields: BelowCount: The count of pixels below the lower bound of threshold range BetweenCount: The count of pixels in the threshold range AboveCount: The count of pixels above the upper bound of threshold range 返回结构是一个序列化的JSON字符串，包含以下字段： BelowCount: 灰度值在阈值范围以下的像素总数 BetweenCount: 灰度值在阈值范围之间的像素总数 AboveCount: 灰度值在阈值范围以上的像素总数 . 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. 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 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 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. 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 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.
Open source. One binary. Zero dependencies.
