Delete vectors by ID.
AI agents call ruvector_delete to permanently remove resources in Claude Flow — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool performs deletion of data (vectors) by identifier. Deletion is irreversible and cannot be undone, placing it in the Destructive category. Severity is high because bulk or mistaken vector deletion could corrupt AI model state, embeddings, or search indices in an enterprise system, though the impact is typically recoverable via backups rather than catastrophic system-wide failure (hence not critical).
From the tool's definition Tool name includes 'delete' and description states 'Delete vectors by ID' — this is an irreversible deletion operation.
Attacks that exploit this kind of access
Delete vectors by ID. It is categorised as a Destructive tool in the Claude Flow MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Claude Flow MCP server in PolicyLayer and add a rule for ruvector_delete: 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 Claude Flow. Nothing to install.
ruvector_delete 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 ruvector_delete 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 ruvector_delete. 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.
ruvector_delete is provided by the Claude Flow MCP server (claude-flow). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
