Implementation Reference
- tools/node.py:400-442 (handler)The handler function for the 'uncordon_node' MCP tool. It uses the Kubernetes CoreV1Api to read the node status, checks if it's already schedulable, and if not, patches the node's spec.unschedulable to False. The @mcp.tool() decorator registers it as an MCP tool.
