disk-health-mcp
MCP server for disk health diagnostics: SMART, NVMe, ZFS, RAID and I/O metrics, with manufacturer-aware severity assessment.
Part of the Server MCP suite. It exposes 13 read-mostly tools and can
use InfluxDB/Telegraf data before falling back to smartctl/nvme-cli over SSH or
locally. Every tool publishes a structured ToolResponse next to the readable text.
Streamable HTTP is available with --transport streamable-http (loopback by default,
bearer token for other addresses).
Storage coverage includes ZFS, mdadm and mergerFS + SnapRAID (SnapRAID status and a mount summary), so the same server can diagnose NAS stacks that do not use ZFS or RAID.
InfluxDB lookups use only successful SMART samples (exit_status = 0) from the last 24
hours, report the sample age and ignore standby rows instead of presenting them as zeroed
health data. run_smart_test pre-flights smartctl and uses -n standby, so it reports an
unavailable tool or a sleeping disk instead of starting a test blindly. Telegraf ->
InfluxDB is the supported SMART source; Prometheus is optional and
the smartmon_* metrics require node_exporter with its smartmon collector. A
loopback-only InfluxDB can be reached with the optional ssh_tunnel block (or a manual
ssh -N -L); see configuration.
uv run --directory apps/disk-health-mcp disk-health-mcp
Requires a config file; see config.example.yaml in this directory. The SMART attribute
database is generated offline with scripts/generate_smartdb.py.
