Flush the entire database and all downloaded files. WARNING: This action is irreversible and will delete all indexed content, documents, and cached files.
AI agents call flush_all to permanently remove resources in Local Search MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool permanently and irreversibly deletes all indexed data, documents, and cached files from the database. This is a destructive operation that cannot be undone, causing significant data loss. While not financial in nature, the blast radius is high because all indexed content becomes unavailable after invocation. The explicit irreversible warning confirms the destructive nature.
From the tool's definition Flush the entire database and all downloaded files. WARNING: This action is irreversible and will delete all indexed content, documents, and cached files.

Flush the entire database and all downloaded files. WARNING: This action is irreversible and will delete all indexed content, documents, and cached files. It is categorised as a Destructive tool in the Local Search MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Local Search MCP Server MCP server in PolicyLayer and add a rule for flush_all: 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 Local Search MCP Server. Nothing to install.
flush_all 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 flush_all 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 flush_all. 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.
flush_all is provided by the Local Search MCP Server MCP server (patrickruddiman/local-search-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
