Koskamo

rust-junosmcp MCP server

A community-built Model Context Protocol server for Juniper Junos and SRX devices, implemented in Rust using rustnetconf. It enables agents to perform network automation tasks with strict security controls, including scoped permissions, audited operations, and two-person change control mechanisms. The server supports configuration writes and reads via a devices.json inventory file, requiring SSH keys or passwords for authentication and strict host-key checking.
