I built 3 MCP servers so I can ask Claude about my DevOps stack

Source: Dev.to

What’s included

Install

npm install -g @peachjed/mcp-prometheus @peachjed/mcp-kubernetes @peachjed/mcp-grafana

Configure Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "prometheus": {
      "command": "mcp-prometheus",
      "env": { "PROMETHEUS_URL": "http://localhost:9090" }
    },
    "kubernetes": {
      "command": "mcp-kubernetes"
    },
    "grafana": {
      "command": "mcp-grafana",
      "env": {
        "GRAFANA_URL": "http://localhost:3000",
        "GRAFANA_TOKEN": "your-token"
      }
    }
  }
}

What you can ask Claude

• “What’s the current CPU usage across all nodes?”
• “Show me the last 50 lines from pod api-server-xyz in production”
• “Are there any firing alerts right now?”
• “List all dashboards in the Infrastructure folder”

How it works

Each server is a small TypeScript process that runs locally via stdio. Claude Desktop spawns it automatically when needed. The Kubernetes server uses your existing ~/.kube/config — no extra auth setup.

Stack

• TypeScript + @modelcontextprotocol/sdk
• @kubernetes/client-node for the k8s server
• Prometheus and Grafana via their HTTP APIs

Source

• GitHub:
• npm packages: @peachjed/mcp-prometheus, @peachjed/mcp-kubernetes, @peachjed/mcp-grafana

Feedback welcome — especially if you use a different observability stack.
