## Claude Desktop Quick Installation
Install path detected from listing signals. Uses `npx` (confidence: high):

```json
"mcpServers": {
  "mcp-alertmanager": {

    "args": ["-y","mcp-alertmanager@latest"]
  }
}
```

A [Model Context Protocol (MCP)](https://modelcontextprotocol.io/) server for Prometheus Alertmanager integration. Native Go binary with built-in Kubernetes connectivity via client-go.

## Installation

### npx

```bash
npx -y mcp-alertmanager@latest
```

### MCP Client Configuration

Add to your MCP client configuration (VS Code, Cursor, Windsurf, etc.):

```json
{
  "mcpServers": {
    "alertmanager": {
      "command": "npx",
      "args": ["-y", "mcp-alertmanager@latest"],
      "env": {
        "ALERTMANAGER_URL": "http://localhost:9093"
      }
    }
  }
}
```

### VS Code

```shell
code --add-mcp '{"name":"alertmanager","command":"npx","args":["-y","mcp-alertmanager@latest"],"env":{"ALERTMANAGER_URL":"http://localhost:9093"}}'
```

### Kubernetes Auto-Connect

Automatically connects to Alertmanager running in OpenShift/Kubernetes via the K8S API service proxy. Uses native kubeconfig/in-cluster config via client-go. No `kubectl` or port-forwarding required.

Default: `openshift-monitoring/alertmanager-operated:9093`

```json
{
  "mcpServers": {
    "alertmanager": {
      "command": "npx",
      "args": ["-y", "mcp-alertmanager@latest"]
    }
  }
}
```

### Binary

Download from [GitHub Releases](https://github.com/jeanlopezxyz/mcp-alertmanager/releases) or build from source:

```bash
make build
./mcp-alertmanager
```

## Configuration

### Environment Variables

| Variable | Description |
|----------|-------------|
| `ALERTMANAGER_URL` | Direct Alertmanager API URL (overrides K8S auto-connect) |

### CLI Flags

| Flag | Description | Default |
|------|-------------|---------|
| `--url` | Direct Alertmanager URL | - |
| `--namespace` | Kubernetes namespace | `openshift-monitoring` |
| `--service` | Kubernetes service name | `alertmanager-operated` |
| `--service-port` | Kubernetes service port | `9093` |
| `--service-scheme` | Service scheme (http/https) | `https` |
| `--kubeconfig` | Path to kubeconfig file | auto-detect |

**Precedence:** `--url` / `ALERTMANAGER_URL` > K8S auto-connect

**Connection strategy:**
1. Direct URL (if `--url` or `ALERTMANAGER_URL` is set)
2. K8S API proxy (auto-detect kubeconfig or in-cluster config)
