## About

# Beszel MCP Server

A Model Context Protocol (MCP) server for the [Beszel](https://github.com/henrygd/beszel) system monitoring tool.

## Overview

This MCP server provides tools to interact with Beszel's PocketBase backend, allowing you to:

- List systems, containers, alerts, and alert history
- Query system statistics
- Query container statistics

**Built with [FastMCP](https://github.com/jlowin/fastmcp)** - A high-level Python framework for building MCP servers with minimal boilerplate. See [Why FastMCP?](docs/WHY_FASTMCP.md) for details.

**Works great with [uv](https://github.com/astral-sh/uv)** - The blazing-fast Python package manager. See [uv Quick Start](docs/UV_QUICKSTART.md) for a 2-minute setup!

## Installation

### Using uv (Recommended)

[uv](https://github.com/astral-sh/uv) is a fast Python package manager that handles virtual environments automatically:

```bash
# Install uv if you haven't already
curl -LsSf https://astral.sh/uv/install.sh | sh

# Install the project
uv pip install -e .

# Or run directly without installing
uv run python -m beszel_mcp
```

### Using pip

```bash
pip install -e .
```

Or install directly from the dependencies:

```bash
pip install fastmcp httpx
```

## Configuration

The server requires the following environment variables:

- `BESZEL_URL`: The URL of your Beszel/PocketBase instance (e.g., `http://localhost:8090`)
- `BESZEL_EMAIL` (optional): Admin email for authentication
- `BESZEL_PASSWORD` (optional): Admin password for authentication

## Usage

### With Claude Desktop

Add to your `claude_desktop_config.json`:

**Using uv (recommended):**
```json
{
  "mcpServers": {
    "beszel": {
      "command": "uvx",
      "args": ["--from", "/path/to/beszel-mcp", "beszel-mcp"],
      "env": {
        "BESZEL_URL": "http://localhost:8090",
        "BESZEL_EMAIL": "your-email@example.com",
        "BESZEL_PASSWORD": "your-password"
      }
    }
  }
}
```

**Or using Python directly:**
```json
{
  "mcpServers": {
    "beszel": {
      "command": "python",
      "args": ["-m", "beszel_mcp"],
      "env": {
        "BESZEL_URL": "http://localhost:8090",
        "BESZEL_EMAIL": "your-email@example.com",
        "BESZEL_PASSWORD": "your-password"
      }
    }
  }
}
```

### Standalone

```bash
export BESZEL_URL="http://localhost:8090"
export BESZEL_EMAIL="your-email@example.com"
export BESZEL_PASSWORD="your-password"

# Using uv (recommended)
uv run beszel-mcp

# Or with python -m
uv run python -m beszel_mcp

# Without uv
python -m beszel_mcp

# Or use fastmcp's CLI
fastmcp run src/beszel_mcp/server.py
```

## Why FastMCP?

This server is built with FastMCP instead of the raw MCP SDK for several reasons:

- **35% less code** - Focus on logic, not boilerplate
- **Automatic schema generation** - Type hints become JSON schemas
- **Clean decorators** - Simple `@mcp.tool()` instead of manual routing
- **Better DX** - Hot reloading, dev mode, and more

See [Why FastMCP?](docs/WHY_FASTMCP.md) for a detailed comparison.
