📈 Metrics & Trends

Terminology quick reference
- appId: Ambari Metrics Service groups every metric under an application identifier (e.g., namenode, datanode, ambari_server, HOST). Think of it as the component or service emitting that timeseries.
- metric name: The fully qualified string Ambari uses for each timeseries (e.g., jvm.JvmMetrics.MemHeapUsedM, dfs.datanode.BytesWritten). Exact names are required when querying AMS.
list_common_metrics_catalog: keyword search against the live metadata-backed metric catalog (cached locally). Use search="heap" or similar to narrow suggestions before running a time-series query.
Example: “Show the heap-related metrics available for the NameNode appId.”
list_ambari_metric_apps: list discovered AMS appId values, optionally including metric counts; pass refresh=true or limit to control output.
Example: “List every appId currently exposed by AMS.”
The natural-language query “AMS에서 사용 가능한 appId 목록만 보여줘” maps to list_ambari_metric_apps and returns the exact identifiers you can copy into other tools.
list_ambari_metrics_metadata: raw AMS metadata explorer (supports app_id, metric_name_filter, host_filter, search, adjustable limit, default 50).
Example: “Give me CPU-related metric metadata under HOST.”
query_ambari_metrics: fetch time-series data; the tool auto-selects curated metric names, falls back to metadata search when needed, and honors Ambari's default precision unless you explicitly supply precision="SECONDS", etc.
Examples: “Plot the last 30 minutes of jvm.JvmMetrics.MemHeapUsedM for the NameNode.” / “Compare jvm.JvmMetrics.MemHeapUsedM for DataNode hosts bigtop-hostname0.demo.local and bigtop-hostname1.demo.local over the past 30 minutes.”
hdfs_dfadmin_report: produce a DFSAdmin-style capacity/DataNode summary (mirrors hdfs dfsadmin -report).

Live Metric Catalog (via AMS metadata)

Metric names are discovered on demand from /ws/v1/timeline/metrics/metadata and cached for quick reuse.
Use list_common_metrics_catalog or the ambari-metrics://catalog/all resource (append ?refresh=true to bypass the cache) to inspect the latest appId → metric mapping. Query ambari-metrics://catalog/apps to list appIds or ambari-metrics://catalog/<appId> for a single app.
Typical appIds include ambari_server, namenode, datanode, nodemanager, resourcemanager, and HOST, but the list adapts to whatever the Ambari Metrics service advertises in your cluster.

🔍 Ambari Metrics Query Requirements (Exact-Match Workflow)

Recent updates removed natural-language metric guessing in favor of deterministic, catalog-driven lookups. Keep the following rules in mind when you (or an LLM agent) call query_ambari_metrics:

Always pass an explicit app_id. If it is missing or unsupported, the tool returns a list of valid appIds and aborts so you can choose one manually.
Specify exact metric names. Use list_common_metrics_catalog(app_id="<target>", search="keyword"), list_ambari_metric_apps (to discover appIds), or the ambari-metrics://catalog/<appId> resource to browse the live per-app metric set and copy the identifier (e.g., jvm.JvmMetrics.MemHeapUsedM).
Host-scope behavior: When hostnames is omitted the API returns cluster-wide aggregates. Provide one or more hosts (comma-separated) to focus on specific nodes.
No fuzzy matches. The server now calls Ambari exactly as requested. If the metric is wrong or empty, Ambari will simply return no datapoints—double-check the identifier via /ws/v1/timeline/metrics/metadata.

Example invocation:

query_ambari_metrics(
  metric_names="jvm.JvmMetrics.MemHeapUsedM",
  app_id="nodemanager",
  duration="1h",
  group_by_host=true
)

For multi-metric lookups, pass a comma-separated list of exact names. Responses document any auto-applied host filters so you can copy/paste them into subsequent requests.

Environment Setup

# 1. Clone the repository
git clone https://github.com/call518/MCP-Ambari-API.git
cd MCP-Ambari-API

# 2. Set up environment configuration
cp .env.example .env

# 3. Configure your Ambari connection in .env file
AMBARI_HOST=your-ambari-host
AMBARI_PORT=your-ambari-port  
AMBARI_USER=your-username
AMBARI_PASS=your-password
AMBARI_CLUSTER_NAME=your-cluster-name

🔐 Security & Authentication

Bearer Token Authentication

For streamable-http mode, this MCP server supports Bearer token authentication to secure remote access. This is especially important when running the server in production environments.

Configuration

Enable Authentication:

# In .env file
REMOTE_AUTH_ENABLE=true
REMOTE_SECRET_KEY=your-secure-secret-key-here

Or via CLI:

python -m mcp_ambari_api --type streamable-http --auth-enable --secret-key your-secure-secret-key-here

Security Levels

stdio mode (Default): Local-only access, no authentication needed
streamable-http + REMOTE_AUTH_ENABLE=false/undefined: Remote access without authentication ⚠️ NOT RECOMMENDED for production
streamable-http + REMOTE_AUTH_ENABLE=true: Remote access with Bearer token authentication ✅ RECOMMENDED for production

🔒 Default Policy: REMOTE_AUTH_ENABLE defaults to false if undefined, empty, or null. This ensures the server starts even without explicit authentication configuration.

Client Configuration

When authentication is enabled, MCP clients must include the Bearer token in the Authorization header:

{
  "mcpServers": {
    "mcp-ambari-api": {
      "type": "streamable-http",
      "url": "http://your-server:8000/mcp",
      "headers": {
        "Authorization": "Bearer your-secure-secret-key-here"
      }
    }
  }
}

Security Best Practices

Always enable authentication when using streamable-http mode in production
Use strong, randomly generated secret keys (32+ characters recommended)
Use HTTPS when possible (configure reverse proxy with SSL/TLS)
Restrict network access using firewalls or network policies
Rotate secret keys regularly for enhanced security
Monitor access logs for unauthorized access attempts

Error Handling

When authentication fails, the server returns:

401 Unauthorized for missing or invalid tokens
Detailed error messages in JSON format for debugging

🛠️ Adding Custom Tools

After you've thoroughly explored the existing functionality, you might want to add your own custom tools for specific monitoring or management needs. This MCP server is designed for easy extensibility.

Step-by-Step Guide

1. Add Helper Functions (Optional)

Add reusable data functions to src/mcp_ambari_api/functions.py:

async def get_your_custom_data(target_resource: str = None) -> List[Dict[str, Any]]:
    """Your custom data retrieval function."""
    # Example implementation - adapt to your Ambari service
    endpoint = f"/clusters/{AMBARI_CLUSTER_NAME}/your_custom_endpoint"
    if target_resource:
        endpoint += f"/{target_resource}"
    
    response_data = await make_ambari_request(endpoint)
    
    if response_data is None or "items" not in response_data:
        return []
    
    return response_data["items"]

2. Create Your MCP Tool

Add your tool function to src/mcp_ambari_api/mcp_main.py:

@mcp.tool()
@log_tool
async def get_your_custom_analysis(limit: int = 50, target_name: Optional[str] = None) -> str:
    """
    [Tool Purpose]: Brief description of what your tool does

    Args:
        limit: Maximum results (1-100)
        target_name: Target resource/service name (optional)
    
    Returns:
        Formatted analysis results (success: formatted data, failure: English error message)
    """
    try:
        limit = max(1, min(limit, 100))  # Always validate input
        
        results = await get_your_custom_data(target_resource=target_name)
        
        if not results:
            return f"No custom analysis data found{' for ' + target_name if target_name else ''}."
        
        # Apply limit
        limited_results = results[:limit]
        
        # Format output
        result_lines = [
            f"Custom Analysis Results{' for ' + target_name if target_name else ''}",
            "=" * 50,
            f"Found: {len(limited_results)} items (total: {len(results)})",
            ""
        ]
        
        for i, item in enumerate(limited_results, 1):
            # Customize this formatting based on your data structure
            name = item.get("name", "Unknown")
            status = item.get("status", "N/A")
            result_lines.append(f"[{i}] {name}: {status}")
        
        return "\n".join(result_lines)
        
    except Exception as e:
        return f"Error: Exception occurred while retrieving custom analysis - {str(e)}"

3. Update Imports

Add your helper function to the imports section in src/mcp_ambari_api/mcp_main.py:

from mcp_ambari_api.functions import (
    format_timestamp,
    format_single_host_details,
    make_ambari_request,
    # ... existing imports ...
    get_your_custom_data,  # Add your new function here
)

4. Update Prompt Template (Recommended)

Add your tool description to src/mcp_ambari_api/prompt_template.md for better AI recognition:

### Custom Analysis Tools

**get_your_custom_analysis**
- "Show me custom analysis results"
- "Get custom analysis for target_name"
- "Display custom monitoring data"
- 📋 **Features**: Custom data aggregation, resource monitoring, performance insights

5. Test Your Tool

# Local testing with MCP Inspector
