Grafana MCP Server

Available Tools

The following tools are available via the MCP server:

• test_connection: Verify connectivity to your Grafana instance and configuration.
• grafana_promql_query: Execute PromQL queries against Grafana's Prometheus datasource. Fetches metrics data using PromQL expressions, optimizes time series responses to reduce token size.
• grafana_loki_query: Query Grafana Loki for log data. Fetches logs for a specified duration (e.g., '5m', '1h', '2d'), converts relative time to absolute timestamps.
• grafana_get_dashboard_config: Retrieves dashboard configuration details from the database. Queries the connectors_connectormetadatamodelstore table for dashboard metadata.
• grafana_query_dashboard_panels: Execute queries for specific dashboard panels. Can query up to 4 panels at once, supports template variables, optimizes metrics data.
• grafana_fetch_label_values: Fetch label values for dashboard variables from Prometheus datasource. Retrieves available values for specific labels (e.g., 'instance', 'job'). Supports optional metric filtering.
• grafana_fetch_dashboard_variables: Fetch all variables and their values from a Grafana dashboard. Retrieves dashboard template variables and their current values.
• grafana_fetch_all_dashboards: Fetch all dashboards from Grafana with basic information like title, UID, folder, tags, etc.
• grafana_fetch_datasources: Fetch all datasources from Grafana with their configuration details.
• grafana_fetch_folders: Fetch all folders from Grafana with their metadata and permissions.

🚀 Usage & Requirements

1. Get Your Grafana API Endpoint & Service Account Token

1. Ensure you have a running Grafana instance (self-hosted or cloud).
2. Generate a Service Account Token from your Grafana UI:
   • Create Service Account: In your Grafana dashboard, navigate to Admin >> Users & Access >> Service Accounts >> Create a Service Account with Viewer permissions
   • Generate Service Account Key: Within Service Account, create a new Service Account token.
   • Copy the service account token (starts with glsa_)

2. Installation & Running Options

2A. Install & Run with uv (Recommended for Local Development)

2A.1. Install dependencies with uv

uv venv .venv
source .venv/bin/activate
uv sync

2A.2. Run the server with uv

uv run -m src.grafana_mcp_server.mcp_server

• You can also use uv to run any other entrypoint scripts as needed.
• Make sure your config.yaml is in the same directory as mcp_server.py or set the required environment variables (see Configuration section).

---

2B. Run with Docker Compose (Recommended for Production/Containerized Environments)

1. Edit grafana-mcp-server/src/grafana_mcp_server/config.yaml with your Grafana details (host, API key).
2. Start the server:

   docker compose up -d
   

   • The server will run in HTTP (SSE) mode on port 8000 by default.
   • You can override configuration with environment variables (see below).

---

3. Configuration

The server loads configuration in the following order of precedence:

1. Environment Variables (recommended for Docker/CI):
   • GRAFANA_HOST: Grafana instance URL (e.g. https://your-grafana-instance.com)
   • GRAFANA_API_KEY: Grafana Service Account Token (required)
   • GRAFANA_SSL_VERIFY: true or false (default: true)
   • MCP_SERVER_PORT: Port to run the server on (default: 8000)
   • MCP_SERVER_DEBUG: true or false (default: true)
2. YAML file fallback (config.yaml):

   grafana:
     host: "https://your-grafana-instance.com"
     api_key: "your-grafana-api-key-here"
     ssl_verify: "true"
   server:
     port: 8000
     debug: true

4. Integration with AI Assistants (e.g., Claude Desktop, Cursor)

You can integrate this MCP server with any tool that supports the MCP protocol. Here are the main options:

4A. Using Docker (with environment variables)

{
  "mcpServers": {
    "grafana": {
      "command": "docker",
      "args": [
        "run",
        "--rm",
        "-i",
        "-e",
        "GRAFANA_HOST",
        "-e",
        "GRAFANA_API_KEY",
        "-e",
        "GRAFANA_SSL_VERIFY",
        "drdroidlab/grafana-mcp-server",
        "-t",
        "stdio"
      ],
      "env": {
        "GRAFANA_HOST": "https://your-grafana-instance.com",
        "GRAFANA_API_KEY": "your-grafana-api-key-here",
        "GRAFANA_SSL_VERIFY": "true"
      }
    }
  }
}

• The -t stdio argument is supported for compatibility with Docker MCP clients (forces stdio handshake mode).
• Adjust the volume path or environment variables as needed for your deployment.

4B. Connecting to an Already Running MCP Server (HTTP/SSE)

If you have an MCP server already running (e.g., on a remote host, cloud VM, or Kubernetes), you can connect your AI assistant or tool directly to its HTTP endpoint.

{
  "mcpServers": {
    "grafana": {
      "url": "http://your-server-host:8000/mcp"
    }
  }
}

• Replace your-server-host with the actual host where your MCP server is running.
• For local setup, use localhost as the server host (i.e., http://localhost:8000/mcp).
• Use http for local or unsecured deployments, and https for production or secured deployments.
• Make sure the server is accessible from your client machine (check firewall, security group, etc.).

---

Health Check

curl http://localhost:8000/health

The server runs on port 8000 by default.

6. Troubleshooting

Common Issues

1. Connection Failed:

   • Verify your Grafana instance is running and accessible
   • Check your API key has proper permissions
   • Ensure SSL verification settings match your setup

2. Authentication Errors:

   • Verify your API key is correct and not expired
   • Check if your Grafana instance requires additional authentication

3. Query Failures:

   • Ensure datasource UIDs are correct
   • Verify PromQL/Loki query syntax
   • Check if the datasource is accessible with your API key

Debug Mode

Enable debug mode to get more detailed logs:

export MCP_SERVER_DEBUG=true
