A Model Context Protocol (MCP) server for Docker, Kubernetes, and Azure Application Insights with advanced log filtering and monitoring capabilities.

## ✨ Features

- 🐳 **Docker** — Container logs, inspect, exec, list containers
- 🐙 **Docker Compose** — Service logs, start/stop/restart services
- ☸️ **Kubernetes** — Pod logs, deployment logs, events, exec into pods
- ☁️ **Azure Application Insights** — Exceptions, traces, requests, metrics
- 🔍 **Log Filtering** — Filter by log level, regex patterns, exclude patterns
- 🌐 **Remote Support** — Connect to remote Docker hosts via SSH or TCP

## ⚙️ Configuration

### 🖥️ Claude Desktop

Add to `~/Library/Application Support/Claude/claude_desktop_config.json` (macOS) or `%APPDATA%\Claude\claude_desktop_config.json` (Windows):

```json
{
  "mcpServers": {
    "container-tools": {
      "command": "/path/to/mcp-container-tools/.venv/bin/python",
      "args": ["-m", "mcp_server.server"],
      "env": {
        "AZURE_LOG_ANALYTICS_WORKSPACE_ID": "your-workspace-id",
        "AZURE_APP_INSIGHTS_RESOURCE_ID": "/subscriptions/.../resourceGroups/.../providers/microsoft.insights/components/..."
      }
    }
  }
}
```

### 💻 Claude Code

Add to `~/.claude/settings.json` or create `.mcp.json` in your project:

```json
{
  "mcpServers": {
    "container-tools": {
      "command": "/path/to/mcp-container-tools/.venv/bin/python",
      "args": ["-m", "mcp_server.server"]
    }
  }
}
```

### ☁️ Azure Authentication

Azure tools use `DefaultAzureCredential` which supports:
- Azure CLI (`az login`)
- Environment variables
- Managed Identity
- Visual Studio Code

```bash
# Easiest: Login with Azure CLI
az login
```

## 📖 Usage Examples

### 🐳 Docker

```python
# Read container logs
docker_logs(container="my-app", tail=100)

# Read logs from last 30 minutes
docker_logs(container="my-app", since="30m")

# Filter by log level (only errors and above)
docker_logs(container="my-app", min_level="error")

# Search for patterns
docker_logs(container="my-app", pattern="timeout|connection refused")

# Exclude health checks
docker_logs(container="my-app", exclude_pattern="GET /health")

# Remote Docker host via SSH
docker_logs(container="my-app", host="ssh://user@server.com")

# List containers
docker_ps(all=True)
```

### 🐙 Docker Compose

```python
# Read service logs
compose_logs(service="api", tail=200)

# Read all services logs
compose_logs(project_dir="/path/to/project")

# Service management
compose_up(service="api", project_dir="/path/to/project")
compose_down(project_dir="/path/to/project")
compose_restart(service="api")
```

### ☸️ Kubernetes

```python
# Read pod logs
k8s_logs(pod="api-7d4b8c6f9-x2k4m", namespace="production")

# Read logs from all pods in a deployment
k8s_deployment_logs(deployment="api", namespace="production")

# Filter logs
k8s_logs(pod="api-*", min_level="warn", pattern="database")

# Use different context
k8s_logs(pod="my-pod", context="production-cluster", namespace="backend")

# List pods
k8s_pods(namespace="all", selector="app=api")

# Get events
k8s_events(namespace="production")

# Execute command in pod
k8s_exec(pod="api-xyz", command="printenv", namespace="production")
```

### ☁️ Azure Application Insights

```python
# Query exceptions from last hour
azure_exceptions(timespan="PT1H", limit=50)

# Get only critical exceptions
azure_exceptions(severity="critical", search="NullReference")

# Query application traces
azure_traces(timespan="PT1H", severity="error")

# Query HTTP requests
azure_requests(timespan="PT1H", failed_only=True)

# Get slow requests (>1 second)
azure_requests(min_duration_ms=1000, limit=20)

# Query external dependencies (SQL, HTTP, etc.)
azure_dependencies(timespan="PT1H", failed_only=True, type_filter="SQL")

# Get metrics
azure_metrics(metric_name="requests/count", timespan="P1D", interval="PT1H")

# Query availability test results
azure_availability(timespan="P1D", failed_only=True)

# Run custom Kusto query
azure_query(query="""
    requests
    | where success == false
    | summarize count() by bin(timestamp, 1h), resultCode
    | order by timestamp desc
""", timespan="P1D")
```

### 🔍 Log Filtering Options

All log tools support these filtering options:

| Option | Description | Example |
|--------|-------------|---------|
| `min_level` | Minimum log level | `"error"`, `"warn"`, `"info"` |
| `pattern` | Regex to include | `"error\|exception"` |
| `exclude_pattern` | Regex to exclude | `"health.*check"` |
| `context_lines` | Lines around matches | `5` |

**Supported log levels:** `trace` → `debug` → `info` → `warn` → `error` → `fatal`

### ⏱️ Timespan Format (Azure)

Azure tools use ISO 8601 duration format:

| Format | Duration |
|--------|----------|
| `PT1H` | 1 hour |
| `PT30M` | 30 minutes |
| `P1D` | 1 day |
| `P7D` | 7 days |
