获取 CA 证书信息和安装指南。抓取 HTTPS 流量需要在设备上安装此证书。
AI agents call get_cert_info to retrieve information from Android Proxy MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a Read operation: it passively retrieves certificate metadata and installation instructions. However, severity is elevated to 'medium' rather than 'low' because the context reveals this tool supports HTTPS traffic interception (MCP server's stated purpose).
From the tool's definition Tool name 'get_cert_info' and description indicate it retrieves/queries CA certificate information and installation guidance ('获取 CA 证书信息和安装指南' = 'Get CA certificate information and installation guide').

Register the Android Proxy MCP server in PolicyLayer and add a rule for get_cert_info: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Android Proxy MCP. Nothing to install.
get_cert_info 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 get_cert_info rule in your PolicyLayer 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 PolicyLayer policy for get_cert_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.
get_cert_info is provided by the Android Proxy MCP server (zhizhuodemao/android_proxy_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
