Junos MCP
A complete operations toolkit for Juniper Networks gear that puts device management and upgrades into Claude's hands. Beyond basic show commands and config retrieval, you get the full lifecycle: firmware staging with checksum verification, pre-flight readiness checks, installation with rollback protection, and scheduled reboots. The push_config tool defaults to dry-run with commit confirmed plus health checks, so you can test changes safely before committing. Batch operations run commands or collect RSI diagnostics across multiple devices in parallel, with tag-based filtering to target specific router groups. The daily_brief tool scans alarms and syslog patterns across your fleet to generate morning health summaries. Built on junos-ops with NETCONF transport, it handles model-specific quirks like EX2300 unlink flags and timeout tuning automatically.

junos-mcp
English | 日本語
MCP (Model Context Protocol) server for junos-ops.
Exposes Juniper Networks device operations to MCP-compatible AI assistants (Claude Desktop, Claude Code, OpenAI Codex, etc.) via STDIO transport. While junos-ops is the CLI tool for humans, junos-mcp is the AI-facing interface to the same powerful engine.
