# Foreman MCP Server

MCP server for Foreman host management and infrastructure automation.

## Features

- List and search hosts from Foreman
- Get detailed host information
- Search by location, OS, and environment
- Generic configuration via environment variables

## Installation

### From PyPI (Recommended)

```bash
pip install foreman-mcp-server
```

### From Source

```bash
git clone https://github.com/rorymcmahon/foreman-mcp-server.git
cd foreman-mcp-server
pip install -e .

## Configuration

Set the following environment variables:

- `FOREMAN_URL`: Base URL of your Foreman instance (e.g., `https://foreman.example.com`)
- `FOREMAN_USERNAME`: Foreman username
- `FOREMAN_PASSWORD`: **Personal Access Token** (not your web login password - create this in User Administration → Personal Access Tokens)
- `FOREMAN_VERIFY_SSL`: Whether to verify SSL certificates (default: `true`)

### Required Permissions

The user account needs the following minimum permissions to use all MCP server tools:

| Resource Type | Permission | Purpose |
|---------------|------------|---------|
| Host | `view_hosts` | List and search hosts, get host details and status |
| Organization | `view_organizations` | List organizations |
| Location | `view_locations` | List locations |
| Hostgroup | `view_hostgroups` | List and search by hostgroups |
| Subnet | `view_subnets` | List subnets and get subnet details |
| Domain | `view_domains` | List domains and get domain details |
| SmartProxy | `view_smart_proxies` | List smart proxies and get proxy details |

### Recommended Roles

Instead of assigning individual permissions, you can use these built-in roles:

| Role | Description | Recommended For |
|------|-------------|-----------------|
| **Viewer** | Read-only access to most Foreman resources | General monitoring and inventory queries |
| **Ansible Tower Inventory Reader** | Specific permissions for inventory access | Automated systems integration |
| **Organization admin** | Full access within assigned organizations | Organization-specific administration |

**Note**: The "Viewer" role provides the most appropriate permissions for this MCP server's read-only operations.
