Installation

Usage

Run the MCP server:

API Examples

The tools are exposed as MCP functions and can be invoked from compatible clients:

• Get pods: get_pods(context="my-context", namespace="default")

• Pod details: get_pod_details(environment="prod", pod_name="nginx-123", namespace="default", context="my-context")

• Get deployments: get_deployments(context="my-context", namespace="default")

• Scale deployment: scale_deployment(namespace="default", deployment_name="web", replicas=5)

• Rollout deployment: rollout_deployment(namespace="default", deployment_name="web")

• Get nodes: get_nodes(context="my-context")

• Get logs: get_logs(context="my-context", environment="prod", pod_name="nginx-123", namespace="default", container="nginx")

• Available contexts: get_available_contexts()

• Change context: set_default_context(context="other-context")
