The implementation of [Model Context Protocol (MCP)](https://modelcontextprotocol.io/) server for [`vmanomaly`](https://docs.victoriametrics.com/anomaly-detection/) - VictoriaMetrics Anomaly Detection product.

This provides seamless integration with `vmanomaly` REST API and [documentation](https://docs.victoriametrics.com/anomaly-detection/) for AI-assisted anomaly detection, model management, and observability insights.

## Features

This MCP server enables AI assistants like Claude to interact with `vmanomaly` for:

- **Health Monitoring**: Check `vmanomaly` server health and build information
- **Model Management**: List, validate, and configure anomaly detection models (like `zscore_online`, `prophet`, and more)
- **Configuration Generation**: Generate complete `vmanomaly` YAML configurations
- **Alert Rule Generation**: Generate [`vmalert`](https://docs.victoriametrics.com/victoriametrics/vmalert/) [alerting rules](https://docs.victoriametrics.com/victoriametrics/vmalert/#alerting-rules) based on [anomaly score metrics](https://docs.victoriametrics.com/anomaly-detection/faq/#what-is-anomaly-score) to simplify alerting setup
- **Documentation Search**: Full-text search across embedded `vmanomaly` documentation with fuzzy matching

The MCP server contains embedded up-to-date `vmanomaly` documentation and is able to search it without online access.

> The quality of the MCP Server and its responses depends very much on the capabilities of your client and the quality of the model you are using.

## Requirements

- [`vmanomaly`](https://docs.victoriametrics.com/anomaly-detection/) instance (version [1.28.3](https://docs.victoriametrics.com/anomaly-detection/changelog/#v1283)+) with REST API access
- Go 1.24 or higher (if building from source)

## Installation

### Go

```bash
go install github.com/VictoriaMetrics/mcp-vmanomaly/cmd/mcp-vmanomaly@latest
```

### Binaries

Download the latest release from [Releases](https://github.com/VictoriaMetrics/mcp-vmanomaly/releases) page and put it to your PATH.

Example for Linux x86_64 (other architectures and platforms are also available):

```bash
latest=$(curl -s https://api.github.com/repos/VictoriaMetrics/mcp-vmanomaly/releases/latest | grep 'tag_name' | cut -d\" -f4)
wget https://github.com/VictoriaMetrics/mcp-vmanomaly/releases/download/$latest/mcp-vmanomaly_Linux_x86_64.tar.gz
tar axvf mcp-vmanomaly_Linux_x86_64.tar.gz
```

### Docker

You can run `vmanomaly` MCP Server using Docker.

This is the easiest way to get started without needing to install Go or build from source.

```bash
docker run -d --name mcp-vmanomaly \
  -e VMANOMALY_ENDPOINT=http://localhost:8490 \
  -e MCP_SERVER_MODE=http \
  -e MCP_LISTEN_ADDR=:8080 \
  -p 8080:8080 \
  ghcr.io/victoriametrics/mcp-vmanomaly
```

You should replace environment variables with your own parameters.

Note that the `MCP_SERVER_MODE=http` flag is used to enable Streamable HTTP mode.
More details about server modes can be found in the [Configuration](#configuration) section.

See available docker images in [github registry](https://github.com/VictoriaMetrics/mcp-vmanomaly/pkgs/container/mcp-vmanomaly).

Also see [Using Docker instead of binary](#using-docker-instead-of-binary) section for more details about using Docker with MCP server with clients in stdio mode.

### Source Code

For building binary from source code you can use the following approach:

- Clone repo:

  ```bash
  git clone https://github.com/VictoriaMetrics/mcp-vmanomaly.git
  cd mcp-vmanomaly
  ```

- Build binary from cloned source code:

  ```bash
  make build
  # after that you can find binary mcp-vmanomaly and copy this file to your PATH or run inplace
  ```

- Build image from cloned source code:

  ```bash
  docker build -t mcp-vmanomaly .
  # after that you can use docker image mcp-vmanomaly for running or pushing
  ```

## Configuration

MCP Server for vmanomaly is configured via environment variables:

| Variable                 | Description                                                                                             | Required | Default          | Allowed values         |
