so do we have a standard annotation for this type of destructive behavior? Is adding destructiveHint not enough? Should we add this to the best practices doc? If this is left off, is there no explicit confirmation from the user to perform this action?

In my testing, I was seeing that without this, the GPT-oss model would be inconsistent in showing a warning. Once I added this, it always shows a confirmation before executing the task.
- Updated the delete/terminate/update tools to add a warning and destructiveHint. Also updated the description to make sure that the AI client asks for a confirmation before proceeding with the tool execution - Generated new denylist from oci-cli version 3.71.1 - Bumped up the versions of servers that have this change - Updated the denylist generator to store the version in the created commands and denylist of the CLI it is generated from

Couple questions:
- Can this list be overwritten? If so, how?
- We should add a section in the readme of this server for this functionality

destructiveHint. Also updated the description to make sure that the AI client asks for a confirmation before proceeding with the tool executionType of change
How Has This Been Tested?
oci-api-mcp-server, you can use the following promptsYou should verify that Cline will not execute the command even when you approve it, as it will hit the denylist
You can set up another MCP server similarly, such as compute. Disable the oci-api-mcp-server and issue a prompt to delete the instance. It should ask for confirmation.
Alternatively, you can also install and start Ollama with gpt-oss and use mcphost to issue prompts. Follow the steps listed at https://github.com/oracle/mcp?tab=readme-ov-file#mcphost
