Clear the logcat buffer
AI agents call clear_logcat to permanently remove resources in Enhanced ADB MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Clearing the logcat buffer permanently discards all currently buffered log entries. This data cannot be recovered once cleared, making it a destructive operation. Severity is medium because while log data loss can impede debugging and incident investigation, it does not affect the device's functional state or user data.
From the tool's definition 'Clear the logcat buffer' — clearing a buffer is an irreversible deletion of existing log data
Attacks that exploit this kind of access
Clear the logcat buffer. It is categorised as a Destructive tool in the Enhanced ADB MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Enhanced ADB MCP Server MCP server in PolicyLayer and add a rule for clear_logcat: 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 Enhanced ADB MCP Server. Nothing to install.
clear_logcat is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the clear_logcat 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 clear_logcat. 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.
clear_logcat is provided by the Enhanced ADB MCP Server MCP server (rahulkr/r_adb_mcp_server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
