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

Get the center of the pattern template. 获取当前配置的模板中心。 The template center indicates the report position of the matching result. 匹配结果将基于配置方式输出不同的中心点坐标。 For example, if the template center is moved to the left-top corner of the template image, we'll then always report the same left-top corner as the matching result. 如若设置匹配图像的左上角点作为中心，所有的匹配结果将总是输出相同的左上角位置作为中心。 返回结构是一个序列化的JSON字符串，属性包括： patX 表示返回模板中心的 x 坐标,double类型。 patY 表示返回模板中心的 y 坐标,double类型。 patAngle 返回模板的 0° 角度 ,double类型。. 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 pat_match_get_pat_center. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Leaper Vision Toolkit MCP server.
pat_match_get_pat_center 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 pat_match_get_pat_center 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 pat_match_get_pat_center. 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.
pat_match_get_pat_center 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.
