clear_log_buffer
AI agents call clear_log_buffer to permanently remove resources in Silotek Serial — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Clearing a log buffer destroys historical firmware debugging data that cannot be recovered. While the blast radius is limited to audit/debug logs rather than production data, the irreversible nature and loss of diagnostic information critical for embedded development make this Destructive.
From the tool's definition Tool name 'clear_log_buffer' indicates irreversible deletion of logged data. The server description emphasizes 'read-only tools' for log retrieval, and this tool's absence from the listed read-only tools (get_log_buffer_info, get_recent_logs,…
Attacks that exploit this kind of access
clear_log_buffer. It is categorised as a Destructive tool in the Silotek Serial MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Silotek Serial MCP server in PolicyLayer and add a rule for clear_log_buffer: 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 Silotek Serial. Nothing to install.
clear_log_buffer 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_log_buffer 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_log_buffer. 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_log_buffer is provided by the Silotek Serial MCP server (jocoin94/silotek-serial-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
