# Update a custom tool

> Partially update a tenant-owned custom tool — any subset of description, JSON-Schema parameters, executor URL, executor secret (rotate or clear with null), enabled flag, timeout, confirmation mode, or spoken messages. The executor URL is re-validated against SSRF/DNS-rebinding rules when changed, and every update takes effect on the next tool call.
