Summary
Adds a wire-level regression test for #21. It proves that an unknown
descriptiontool argument remains an MCPInvalidParams(-32602) response with actionable validation data overPOST /message, and that no BookStack request is made.The transport suite now pins strict validation so an ambient
.envcannot silently make this contract permissive.Relates to #21; this does not close it automatically because the reported generic UI behavior is downstream of this server boundary.
