Delete a published app version.
AI agents call delete_version to permanently remove resources in Run402 — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes a published app version, which cannot be undone. Deletion of versioned software artifacts is a destructive operation that could break user applications, deployments, or rollback capabilities. While not as severe as deleting entire projects or data stores, the irreversibility and potential to disrupt service availability warrants 'high' severity.
From the tool's definition Tool name is 'delete_version' and description states 'Delete a published app version.' The use of 'Delete' indicates irreversible removal of data.
Attacks that exploit this kind of access
Delete a published app version. It is categorised as a Destructive tool in the Run402 MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Run402 MCP server in PolicyLayer and add a rule for delete_version: 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 Run402. Nothing to install.
delete_version 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_version 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_version. 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_version is provided by the Run402 MCP server (kychee-com/run402). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
