Clear all captured requests from the buffer. Use this before starting a new capture session to avoid mixing old and new traffic.
AI agents call clear_buffer to permanently remove resources in Proxypin — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently deletes buffered network traffic without recovery mechanism or undo capability. While the data loss is scoped to in-memory buffers rather than persistent storage, the action is non-reversible and could result in loss of important captured request/response data that an AI agent might need for analysis.
From the tool's definition Tool name 'clear_buffer' and description 'Clear all captured requests from the buffer' indicates irreversible deletion of captured HTTP traffic data.

Clear all captured requests from the buffer. Use this before starting a new capture session to avoid mixing old and new traffic. It is categorised as a Destructive tool in the Proxypin MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Proxypin MCP server in PolicyLayer and add a rule for clear_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 Proxypin. Nothing to install.
clear_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_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_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_buffer is provided by the Proxypin MCP server (k186/proxypin-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
