Convert a BGR color image to grayscale 将 BGR 彩色图像转换为灰度图 - Convert a BGR color image to grayscale using the formula: Gray = 0.114⋅B + 0.587⋅G + 0.299⋅R - The input image must be a BGR color image - The output image will be a grayscale image of the same size as the input - 使用公式 Gray = 0.114⋅B ...
Part of the Leaper Vision Toolkit MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents use image_convert_bgr_to_gray to create or modify resources in Leaper Vision Toolkit. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call image_convert_bgr_to_gray repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Leaper Vision Toolkit.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Convert a BGR color image to grayscale 将 BGR 彩色图像转换为灰度图 - Convert a BGR color image to grayscale using the formula: Gray = 0.114⋅B + 0.587⋅G + 0.299⋅R - The input image must be a BGR color image - The output image will be a grayscale image of the same size as the input - 使用公式 Gray = 0.114⋅B + 0.587⋅G + 0.299⋅R 将 BGR 彩色图像转换为灰度图 - 输入图像必须是 BGR 彩色图像 - 输出图像将是灰度图像，尺寸与输入的彩色图像一致 返回结构是一个序列化的JSON字符串，包含以下字段： ResultImg: 输出结果图像URL地址. It is categorised as a Write tool in the Leaper Vision Toolkit MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Add a rule in your Intercept YAML policy under the tools section for image_convert_bgr_to_gray. 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_convert_bgr_to_gray is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the image_convert_bgr_to_gray 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_convert_bgr_to_gray. 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_convert_bgr_to_gray 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.
