Delete a document from the RAG system by its document ID.
AI agents call delete_document to permanently remove resources in RAG Document Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes documents from the RAG knowledge base. Deletion is irreversible—once a document is deleted, its content and indexed embeddings are lost unless separately backed up. An AI agent misusing this tool could remove critical documentation, research materials, or source code references that the system relies on, degrading system functionality and potentially causing data loss.
From the tool's definition Tool name is 'delete_document' and description states 'Delete a document from the RAG system by its document ID.' The verb 'Delete' combined with removal from a document management system indicates irreversible data removal.
Attacks that exploit this kind of access
Delete a document from the RAG system by its document ID. It is categorised as a Destructive tool in the RAG Document Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the RAG Document Server MCP server in PolicyLayer and add a rule for delete_document: 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 RAG Document Server. Nothing to install.
delete_document 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_document 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_document. 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_document is provided by the RAG Document Server MCP server (jaimeferj/mcp-rag-docs). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
