Delete a RAG collection and all its vectors.
AI agents call rag_delete_collection to permanently remove resources in MCP Math Calculator Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes a RAG collection and all associated vector data without possibility of recovery. It matches the Destructive category definition: 'irreversibly deletes or overwrites data, or actions that cannot be undone (delete, drop, purge, force-push).' The high severity reflects the significant blast radius if an AI agent mistakenly or maliciously deletes important collections containing knowledge…
From the tool's definition Tool name contains "delete" and description states "Delete a RAG collection and all its vectors" - this is an irreversible deletion operation that destroys all data in a collection.
Attacks that exploit this kind of access
Delete a RAG collection and all its vectors. It is categorised as a Destructive tool in the MCP Math Calculator Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the MCP Math Calculator Server MCP server in PolicyLayer and add a rule for rag_delete_collection: 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 Math Calculator Server. Nothing to install.
rag_delete_collection 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 rag_delete_collection 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 rag_delete_collection. 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.
rag_delete_collection is provided by the MCP Math Calculator Server MCP server (r-yash/mcpserver). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
rag_delete_collection is one line of MCP Math Calculator Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
