Clear local cache of specific profiles. For account security, please ensure that there are no open browsers on the device when using this interface.
AI agents call delete-cache to permanently remove resources in TgeBrowser MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Clearing cache irreversibly removes stored data (cookies, session tokens, browsing history, cached credentials) that cannot be recovered once deleted. While not as severe as deleting entire browser profiles, cache deletion is a destructive action that eliminates historical state.
From the tool's definition Tool is named 'delete-cache' and description states 'Clear local cache of specific profiles.' The verb 'clear' indicates irreversible deletion of cached data.

It is categorised as a Destructive tool in the TgeBrowser MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the TgeBrowser MCP Server MCP server in PolicyLayer and add a rule for delete-cache: 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 TgeBrowser MCP Server. Nothing to install.
delete-cache 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 delete-cache 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 delete-cache. 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.
delete-cache is provided by the TgeBrowser MCP Server MCP server (tuguang2025/tgebrowser-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
