# eos-mcp

MCP server for Arista EOS device operations via eAPI.

Exposes EOS show commands, running-config retrieval, configuration push
(via configure session with commit timer), and tech-support collection
to MCP-compatible AI assistants.

## Installation

```bash
pip install eos-mcp
```

## Configuration

Copy `config.ini.example` to `~/.config/eos-mcp/config.ini` and fill in credentials:

```ini
[DEFAULT]
username = admin
password = yourpassword
transport = https
verify = false

[switch1.example.com]
tags = main,dc1

[switch2.example.com]
tags = main,dc1
```

Config file discovery order:
1. `--config_path` argument
2. `EOS_MCP_CONFIG` environment variable
3. `./config.ini` (current directory)
4. `~/.config/eos-mcp/config.ini`

## Usage

```bash
# Verify config and list devices
eos-mcp --check

# Test connectivity to a specific host
eos-mcp --check --check-host switch1.example.com

# Start MCP server (stdio transport, default)
eos-mcp
```
