delete_group
AI agents call delete_group to permanently remove resources in Reka Vision MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deletion of groups cannot be undone and represents permanent data loss. This is the most severe applicable category (Destructive > Execute > Write > Read). High severity because accidental or malicious deletion of video groups and their associated content could result in significant data loss depending on group size and contents.
From the tool's definition Tool name is 'delete_group' which performs an irreversible deletion operation. The sibling tool 'delete_video' on the same server confirms the pattern of deletion tools.
Attacks that exploit this kind of access
delete_group. It is categorised as a Destructive tool in the Reka Vision MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Reka Vision MCP Server MCP server in PolicyLayer and add a rule for delete_group: 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 Reka Vision MCP Server. Nothing to install.
delete_group 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_group 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_group. 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_group is provided by the Reka Vision MCP Server MCP server (reka-ai/reka-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
