delete-knowledge
AI agents call delete-knowledge to permanently remove resources in Better Qdrant — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool name explicitly indicates deletion of knowledge entries from the semantic search/memory system. Even though the description is empty, the naming convention and context (managing long-term memory in Qdrant) strongly suggest this performs irreversible data destruction. This is more severe than Write because deletions cannot be undone without external recovery mechanisms.
From the tool's definition Tool name 'delete-knowledge' combined with sibling operations (store-knowledge, search-knowledge, get-knowledge-by-id) that manage a persistent knowledge base in Qdrant. The 'delete-' prefix indicates irreversible removal of stored data.
Attacks that exploit this kind of access
delete-knowledge. It is categorised as a Destructive tool in the Better Qdrant MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Better Qdrant MCP server in PolicyLayer and add a rule for delete-knowledge: 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 Better Qdrant. Nothing to install.
delete-knowledge 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-knowledge 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-knowledge. 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-knowledge is provided by the Better Qdrant MCP server (jtsang4/better-qdrant-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
delete-knowledge is one line of Better Qdrant's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
