EOS MCP
Connects Claude directly to Arista EOS switches via eAPI to run show commands, pull configs, and push changes through configure sessions with commit timers. You get batch operations across multiple devices, structured device facts (model, serial, uptime), config diffs against rollback checkpoints, and tech-support collection. Handles credentials through INI files with per-device tags for filtering. Reach for this when you're managing Arista gear and want Claude to troubleshoot live network state, validate config changes before committing, or run health checks across your DC fabric without writing custom scripts.

eos-mcp
English | 日本語
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.
Documentation: https://shigechika.github.io/eos-mcp/
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:
EOS_MCP_CONFIGenvironment variable./config.ini(current directory)~/.config/eos-mcp/config.ini
(Individual MCP tool calls may also override the path via a config_path
parameter.)
Write operations
Three tools change device state through a guarded path:
