Check termux-mcp service health (uptime, PID, log size). For auto-recovery.
AI agents call device_health_report to retrieve information from Android MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries system health metrics (uptime, process ID, log size) without modifying, deleting, executing code, or moving money. It is purely observational/diagnostic in nature, making it a Read operation. The low severity reflects minimal blast radius—misuse would only expose benign service metadata. The high confidence reflects clear, unambiguous documentation of a passive monitoring operation.
From the tool's definition Tool description states: 'Check termux-mcp service health (uptime, PID, log size)'. The verb 'check' and the read-only metrics (uptime, PID, log size) indicate data retrieval with no side effects.

Check termux-mcp service health (uptime, PID, log size). For auto-recovery. It is categorised as a Read tool in the Android MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Android MCP Server MCP server in PolicyLayer and add a rule for device_health_report: 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 MCP Server. Nothing to install.
device_health_report 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 device_health_report 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 device_health_report. 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.
device_health_report is provided by the Android MCP Server MCP server (wujie272/android-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
