Pyats

Acerca de

Pyats provides a Model Context Protocol (MCP) Server that wraps Cisco pyATS and Genie functionality. It allows structured, model-driven interaction with network devices over STDIO using the JSON-RPC 2.0 protocol. Operating entirely via STDIO, this server minimizes the attack surface area, maximizing portability for secure, embedded, containerized, or LangGraph-based tool integrations. It supports safe execution of validated CLI commands, controlled configuration changes, and returns structured (parsed) or raw output, exposing a set of well-defined tools.
