⚙️ Configuration

🖥️ Claude Desktop

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

{
  "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:

{
  "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

# Easiest: Login with Azure CLI
az login

📖 Usage Examples

🐳 Docker

# 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

# 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

# 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

# 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
