MCP server for Arista EOS device operations via eAPI

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

pip install eos-mcp

Configuration

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

[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

# 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
