Prometheus MCP Server

What does “Prometheus” MCP Server do?

The Prometheus MCP Server is a Model Context Protocol (MCP) implementation that enables AI assistants to interact with Prometheus metrics using standardized interfaces. By acting as a bridge between AI agents and Prometheus, it allows for seamless execution of PromQL queries, discovery and exploration of metric data, and provides direct access to time-series analytics. This empowers developers and AI tools to automate monitoring, analyze infrastructure health, and gain operational insights without manual data retrieval. Key features include metric listing, metadata access, support for both instant and range queries, and configurable authentication (basic auth or bearer token). The server is also containerized for easy deployment and can be flexibly integrated with various AI development workflows.

Use Cases of this MCP Server

• Automated Infrastructure Monitoring: AI assistants can query Prometheus to check health and performance indicators, automating alerting and anomaly detection.
• DevOps Analytics: Developers can use the server to analyze historical trends, usage patterns, and resource bottlenecks.
• Incident Triage: When incidents occur, AI agents can pull relevant metric snapshots and time ranges to assist in root cause analysis.
• Custom Dashboard Generation: Programmatically fetch metrics and metadata to create or update dashboards integrated with AI-driven insights.
• Security and Compliance Auditing: Use querying capabilities to gather metrics relevant for compliance checks and reporting, all automated through AI workflows.

How to set it up

Windsurf

No specific instructions are provided for Windsurf in the repository.

Claude

1. Ensure your Prometheus server is accessible from the deployment environment.
2. Configure environment variables for Prometheus (e.g., PROMETHEUS_URL, credentials).
3. In Claude Desktop, add the server configuration to your mcpServers object:

   {
     "mcpServers": {
       "prometheus": {
         "command": "uv",
         "args": [
           "--directory",
           "<full path to prometheus-mcp-server directory>",
           "run",
           "src/prometheus_mcp_server/main.py"
         ],
         "env": {
           "PROMETHEUS_URL": "http://your-prometheus-server:9090",
           "PROMETHEUS_USERNAME": "your_username",
           "PROMETHEUS_PASSWORD": "your_password"
         }
       }
     }
   }
   

4. Save the configuration and restart Claude Desktop.
5. Verify that the Prometheus server is listed and accessible.

Note: If you see Error: spawn uv ENOENT, specify the full path to uv or set the environment variable NO_UV=1 in the configuration.

Securing API Keys
Sensitive values such as API keys, usernames, and passwords should be set via environment variables.
Example (in JSON configuration):

"env": {
  "PROMETHEUS_URL": "http://your-prometheus-server:9090",
  "PROMETHEUS_USERNAME": "your_username",
  "PROMETHEUS_PASSWORD": "your_password"
}

How to use this MCP inside flows

Using MCP in FlowHunt

To integrate MCP servers into your FlowHunt workflow, start by adding the MCP component to your flow and connecting it to your AI agent:

Click on the MCP component to open the configuration panel. In the system MCP configuration section, insert your MCP server details using this JSON format:

{
  "prometheus": {
    "transport": "streamable_http",
    "url": "https://yourmcpserver.example/pathtothemcp/url"
  }
}

Once configured, the AI agent is now able to use this MCP as a tool with access to all its functions and capabilities. Remember to change “prometheus” to whatever the actual name of your MCP server is and replace the URL with your own MCP server URL.

Overview

Based on the above, Prometheus MCP Server offers strong tool integration and clear API key security. Some advanced MCP features (like prompts, explicit resources, sampling, and roots) are not documented or implemented.

Our opinion

The Prometheus MCP Server scores well for core MCP tool support and practical integration, but lacks documentation or implementation for prompts, resources, and advanced MCP features. It is reliable for metric analysis but not a full-featured MCP example. Score: 6/10.
