Manages the full lifecycle of any systemd unit — not just Podman-managed containers: listing, status, lifecycle control, unit file authoring and decommissioning, journal queries, failed-unit and job triage, timers, host info, and login sessions.\n\n## Installation\n\n```bash\n# uvx (zero-install)\nuvx mcp-systemd-crunchtools\n\n# pip\npip install mcp-systemd-crunchtools\n\n# Container\npodman run \\\n  -v /run/dbus/system_bus_socket:/run/dbus/system_bus_socket \\\n  -v /etc/systemd/system:/etc/systemd/system:Z \\\n  --security-opt label=type:container_runtime_t \\\n  quay.io/crunchtools/mcp-systemd\n```\n\nThe D-Bus socket mount is required for every tool. The `/etc/systemd/system` mount is only required for `unit_file_write_tool` and `unit_file_remove_tool` — omit it to run the server read/lifecycle-only.\n\n## Configuration\n\n| Variable | Required | Default | Description |\n|----------|----------|---------|-------------|\n| `DBUS_SYSTEM_BUS_SOCKET` | No | `/run/dbus/system_bus_socket` | D-Bus system bus socket path |\n| `SYSTEMD_UNIT_DIR` | No | `/etc/systemd/system` | Directory unit_file_write/remove operate on |\n| `SYSTEMD_EXTRA_PROTECTED_UNITS` | No | — | Comma-separated units added to the built-in denylist |\n\n## Protected units\n\n`unit_stop`, `unit_restart`, `unit_disable`, `unit_mask`, and `unit_file_remove` refuse to act on a small built-in denylist of core system units (dbus, sshd, networking, logind, journald). This cannot be bypassed — it exists so an agent can't take down the box it's running on. Add more units with `SYSTEMD_EXTRA_PROTECTED_UNITS`.\n\n## Claude Code Integration\n\n```bash\nclaude mcp add mcp-systemd-crunchtools \\\n  -- uvx mcp-systemd-crunchtools\n```\n\n## Tools (21)\n\n### Units (3)\n| Tool | Description |\n|------|-------------|\n| `unit_list` | List loaded units or installed unit files |\n| `unit_status` | Curated status (active state, PID, memory, CPU…","publisher":{"name":"crunchtools.com","url":null},"homepage":null,"repository":null,"version":"0.3.1","license":null,"protocols":["mcp"],"tags":["dbus","fastmcp","mcp","sysadmin","systemd"],"pricing":null,"endpoints":[{"url":"pypi:mcp-systemd-crunchtools","type":"package_pypi","auth":null,"probeable":false}],"skills":null,"tools":null,"extra":null,"attribution":{"kind":"pypi","name":"pypi","summary":"pypi","version":"pypi","description":"pypi","publisherName":"pypi"}},"derived":{"capabilities":[{"slug":"dev.filesystem","name":"Filesystem","confidence":0.802,"provenance":"derived"}],"categories":["dev"],"language":"en"},"observed":{"status":"unknown","statusReason":"Distributed as a package to run locally; no network endpoint to check.","lastOkAt":null,"lastProbedAt":null,"statusComputedAt":null,"reliability30d":null,"latestObservations":[],"tools":null,"package":{"name":"mcp-systemd-crunchtools","registry":"pypi","observedAt":"2026-11-03T16:26:03.704Z","publishedAt":"2026-10-31T23:06:31.857972Z","latestVersion":"0.3.1"},"toolSurface":null,"endpointFacts":[]},"verification":{"claimed":false,"claimedAt":null,"proofs":[]},"provenance":{"sources":[{"source":"pypi","key":"mcp-systemd-crunchtools","url":"https://pypi.org/project/mcp-systemd-crunchtools/","firstSeenAt":"2026-09-22T07:24:38.046Z","fetchedAt":"2026-11-03T16:24:44.672Z","normalizedAt":"2026-11-03T16:24:44.672Z"}]},"firstSeenAt":"2026-09-22T07:24:38.046Z","updatedAt":"2026-11-03T16:26:03.704Z"}
