v1.12.0 - SSE Transport Fix & In-Cluster Kubernetes Config

What's New in v1.12.0

SSE Transport Fix

• Fixed 'FastMCP' object has no attribute 'run_sse_async' error when using FastMCP 3.0.0b1

• SSE endpoints: GET /sse (events), POST /messages/ (messages)

In-Cluster Kubernetes Config Support

• Added k8s_config.py module that automatically handles Kubernetes authentication
• Tries in-cluster config first when running inside a Kubernetes pod
• Falls back to kubeconfig file for local development
• Enables kubectl-mcp-server to work seamlessly with Kubernetes service accounts

kagent Integration

• Added deploy/kagent/remotemcpserver.yaml for kagent RemoteMCPServer CRD
• Added deploy/kagent/agent-kubectl-mcp.yaml for kagent Agent CRD
• Successfully tested with kagent v0.7.9 - all 121 tools discovered
