image_info

Part of the Leaper Vision Toolkit MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

// WHEN AI AGENTS USE THIS TOOL

AI agents call image_info 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.

// WHY ENFORCE A POLICY ON IMAGE_INFO

Even though image_info 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.

// RECOMMENDED POLICY

Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

What does the image_info tool do? +

获取输入图像的图片信息。返回结构是一个序列化的JSON字符串，包含以下字段： BytesPerLine : 每行像素数据的字节数，包含行末用于对齐的字节。 Height: 图像的高度，行的总数。 Width: 图像的宽度，列的总数。 ImageFormat: 图像类型(LPVImageFormatGrayscale8：该图像为 8 位灰度图。LPVImageFormatColor24 ：该图像为 24 位 BGR 彩色图，每个通道 8 位。LPVImageFormatGrayscale16:该图像为 16 位灰度图 ) Get the input image info. Returns a serialized JSON string containing the following fields: BytesPerLine : The number of bytes contained in a row, include the padding bytes. Height: The height of the image, number of rows. Width: The width of the image, number of columns. ImageFormat: The format of the image. (LPVImageFormatGrayscale8：The image is stored using an 8-bit grayscale format. LPVImageFormatColor24 ：The image is stored using a 24-bit BGR color format (8-8-8).LPVImageFormatGrayscale16:The image is stored using an 16-bit grayscale format. ) . It is categorised as a Read tool in the Leaper Vision Toolkit MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on image_info? +

Add a rule in your Intercept YAML policy under the tools section for image_info. 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 image_info? +

image_info is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit image_info? +

Yes. Add a rate_limit block to the image_info 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 image_info completely? +

Set action: deny in the Intercept policy for image_info. 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 image_info? +

image_info 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.
