The pyATS MCP Server is a Model Context Protocol Server that integrates with Cisco pyATS and Genie, enabling structured interaction with network devices using JSON-RPC 2.0 over STDIO.
The pyATS MCP Server is designed to facilitate secure and structured communication with Cisco network devices by leveraging the pyATS and Genie frameworks. It operates using the JSON-RPC 2.0 protocol over standard input/output (STDIO), making it suitable for secure, embedded, and containerized environments. The server connects to devices defined in a pyATS testbed, allowing for the execution of validated CLI commands, controlled configuration changes, and retrieval of structured or raw outputs. It provides a set of tools for network operations, all while ensuring minimal surface area and maximum portability. The server's STDIO-based communication model is particularly advantageous for integration with LangGraph pipelines, as it avoids the need for HTTP ports or REST endpoints. Security is a key focus, with input validation and command restrictions in place to prevent unsafe operations.
Features
- Secure STDIO Communication: Operates entirely over STDIN/STDOUT, enhancing security and portability.
- Validated Command Execution: Supports safe execution of CLI commands with input validation using Pydantic.
- Structured Output: Returns both parsed and raw outputs for network operations.
- Docker Support: Easily containerized for deployment in various environments.
- LangGraph Integration: Seamlessly integrates with LangGraph pipelines for tool invocation.
