VictoriaMetrics MCP Server

The implementation of Model Context Protocol (MCP) server for VictoriaMetrics

Installation

Add the following to your MCP client configuration file.

Configuration

{
  "mcpServers": {
    "victoriametrics-mcp-victoriametrics": {
      "url": "https://play-mcp.victoriametrics.com/mcp"
    }
  }
}

You can access and manage your VictoriaMetrics instance through an MCP server that exposes VictoriaMetrics read-only APIs via convenient prompts and tools. This enables fast querying, metric exploration, rule testing, documentation search, and automation workflows without complex client setups.

How to use

Connect to the public test MCP server to explore capabilities quickly. Use the available tools to query metrics, list metrics and labels, inspect time series, test alerting rules, and search embedded documentation. You can mix tool usage with prompts to build custom monitoring workflows. For example, you can query PromQL-like expressions, list available metrics, inspect label values, or fetch documentation snippets directly from the embedded docs.

How to install

# Prerequisites
- Docker (recommended for quick start) or a Go toolchain if you prefer building/running locally
- Access to the public MCP endpoint for VictoriaMetrics (optional for testing)

# Option 1: Run via Docker (recommended for quick start)
docker run -d --name mcp-victoriametrics \
  -e VM_INSTANCE_ENTRYPOINT=https://play.victoriametrics.com \
  -e VM_INSTANCE_TYPE=cluster \
  -e MCP_SERVER_MODE=sse \
  -e MCP_LISTEN_ADDR=:8080 \
  -p 8080:8080 \
  ghcr.io/victoriametrics-community/mcp-victoriametrics

# Option 2: Build from source (Go)

go install github.com/VictoriaMetrics-Community/mcp-victoriametrics/cmd/mcp-victoriametrics@latest

# Option 3: Download pre-built binaries (Linux x86_64 example)
latest=$(curl -s https://api.github.com/repos/VictoriaMetrics-Community/mcp-victoriametrics/releases/latest | grep 'tag_name' | cut -d" -f4)
wget https://github.com/VictoriaMetrics-Community/mcp-victoriametrics/releases/download/$latest/mcp-victoriametrics_Linux_x86_64.tar.gz
tar axvf mcp-victoriametrics_Linux_x86_64.tar.gz

Additional setup and configuration

This MCP server is designed to connect to VictoriaMetrics instances and expose a set of tools for querying, analyzing, and managing your metrics. You can enable or disable specific tools via environment configuration when you run the server. For public testing, you can use the provided test endpoint and start experimenting with client prompts and built-in documentation search.

Configuration and endpoints

The MCP server exposes several modes of transport and endpoints depending on how you run it. In public testing, you’ll typically interact with the HTTP streaming endpoint. The server also serves an internal health and metrics surface to monitor the MCP broker.

To start the server in HTTP mode for streaming and interaction, use the following configuration snippet if you are integrating with an MCP client that expects an HTTP transport.

Public test MCP endpoint

{
  "type": "http",
  "name": "victoriametrics_play",
  "url": "https://play-mcp.victoriametrics.com/mcp",
  "args": []
}
