Clear data from the RAG system
AI agents call clear_data to permanently remove resources in MCP RAG — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool performs irreversible deletion of data at scale within the RAG system. While the exact scope (all data vs. scoped subsets) is not fully specified, the semantic meaning of 'clear_data' in a data storage system indicates permanent removal that cannot be undone. This is more severe than Write (reversible modifications) and justifies the Destructive category.
From the tool's definition Tool name 'clear_data' with description 'Clear data from the RAG system' indicates irreversible deletion of stored data (files, embeddings, or memory vectors).
Attacks that exploit this kind of access
Clear data from the RAG system. It is categorised as a Destructive tool in the MCP RAG MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the MCP RAG MCP server in PolicyLayer and add a rule for clear_data: 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 MCP RAG. Nothing to install.
clear_data 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_data 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_data. 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_data is provided by the MCP RAG MCP server (santis84/mcp-rag). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
