Clear a code generation session without generating a test
AI agents call clear_codegen_session to permanently remove resources in Playwright MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Clearing a session irreversibly discards accumulated code generation state and data without generating any output. This action cannot be undone — the session data is permanently lost. Severity is medium because the blast radius is limited to losing work-in-progress test code rather than affecting production systems.

Attacks that exploit this kind of access
Clear a code generation session without generating a test. It is categorised as a Destructive tool in the Playwright MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Playwright MCP Server MCP server in PolicyLayer and add a rule for clear_codegen_session: 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 Playwright MCP Server. Nothing to install.
clear_codegen_session 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_codegen_session 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_codegen_session. 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_codegen_session is provided by the Playwright MCP Server MCP server (vinothbhc1986/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
