Delete an API version
AI agents call delete_api_version to permanently remove resources in Postman — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool removes an API version, which is an irreversible destructive action. Once deleted, the API version and its associated configuration cannot be recovered through normal means. While not as critical as deleting an entire API, the deletion of a version represents permanent data loss and warrants a Destructive classification with high severity.
From the tool's definition Tool name: delete_api_version; Tool description: Delete an API version. The verb 'Delete' indicates irreversible removal of data.

delete_api_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_api_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_api_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_api_version is provided by the Postman MCP server (postmanv3/postman-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
