A caller of the MCP endpoint can invoke endpoints the OpenAPI document
never declared, under the declared tool's HTTP method, using the credentials the
Route adds. This issue affects Apache APISIX: from 3.19.0 before 3.20.0.
Users are recommended to upgrade to version 3.20.0, which fixes the issue.
