AI image generation using various models

62(and growing) read-only diagnostic tools that let Claude inspect your Linux fleet without touching it. Files, systemd, performance, networking, processes, disks, kernel, packages, Docker — each a hardened wrapper around a command you already trust, run over your own SSH config. Read-only by construction: there is no code path that restarts a service, edits a file, installs a package, or runs anything that mutates state. Every argument is validated and shell-quoted, flag injection is killed by per-tool whitelists, and hosts can be pinned to an allowlist. Point it at production and sleep. Run any tool on one host, or pass a list to fan out in parallel — bounded, with a hard 25-host ceiling so a curious model can't trigger an SSH storm. Why - Can't break anything — no mutate path exists. No restart, no edit, no install, no -exec. - Injection-hardened — shlex.quote everywhere, flag whitelists, NUL/newline rejection, host allowlist. - Your SSH, your rules — uses your ssh/agent or any wrapper (tsh ssh, jump hosts). Server never sees a credential. - Bounded — byte-capped output, per-call timeouts, capped multi-host fan-out. - Auditable — structured {stdout, stderr, exit_code, truncated} + optional JSONL logs with per-call IDs. Setup Python via uv. One mcpServers entry, tuned by env vars. Works with Claude Desktop and Claude Code.
