## FAQ

### Can I use node9 as an MCP server?

Yes, it can run as an MCP server so an agent can read its status, posture, audit record, and policy from within the conversation.

### What happens when a tool call is held for approval?

The action is paused and waits for your approval directly in the agent conversation or through a team approver.
