MCP Kubernetes

Model Context Protocol server for Kubernetes operations.

Description

This project implements an MCP (Model Context Protocol) server for advanced management of Kubernetes clusters. It provides tools to query, manage, and monitor resources such as pods, deployments, nodes, and logs, with support for multiple contexts and namespaces.

• 🖥️ Node Management:

  • 🗂️ List nodes with capacity, status, roles, and cluster summary.

• 📄 Pod Logs:

  • 📝 Retrieve logs from specific pods and containers, with options for previous logs and line count.

• 🔄 Multi-context Support:

  • 🔎 Query and switch Kubernetes contexts.

  • ⚙️ Set default context.

• ⚙️ Configuration and Logging:

Installation

pip install -r requirements.txt

Usage

Run the MCP server:

python src/mcp_kubernetes/main.py

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")
