Report local system health: disk, memory, load, uptime, container count.

Reads from /proc and shells out to df, uptime, docker ps. Designed for the host the MCP server runs on.

List Grafana alert rules with their current state.

Queries the Grafana Prometheus-style rules API. Reads credentials from the config (Grafana URL + user) and from the env var named in grafana.password_env (defaults to GRAFANA_PASSWORD). Returns a dict with alerts grouped by state (firing/pending/inactive/no_data/error).

Query a freqtrade bot's REST API for its current trading state.

bot_name must match a key under freqtrade.bots in config (e.g. 'steady', 'fun'). Reads basic-auth credentials from the env vars named in user_env / pass_env on the bot's config entry.

Returns a dict with: bot_name, dry_run, strategy, timeframe, exchange, closed_trade_count, open_trade_count, realised_p_and_l_fiat, realised_p_and_l_pct, total_p_and_l_fiat, total_p_and_l_pct, win_rate, open_positions (list of {pair, opened, current_pnl_fiat, current_pnl_pct}).

Returns {"error": "..."} on any failure (unknown bot, missing creds, API down).

Return structured docker-ps output: per-container name, image, state, status, ports, age.

Shells out to docker ps with a tab-separated format string. Returns a list of containers plus a summary dict. Read-only — does not stop/restart anything.

Returns {"error": "..."} if docker isn't installed or the docker socket is unreachable.

Search container/syslog logs via Loki LogQL.

query: LogQL query string, e.g. '{container="grafana"}' or '{container=~".+"} |= "ERROR"' since: how far back, e.g. '1h', '30m', '7d' (Loki duration syntax) limit: max log lines to return (Loki default = 100, hard-capped here at 1000)

Returns a dict with: total_streams, total_lines, streams (list of {labels, lines}). Lines are timestamp-sorted oldest-first. Returns {"error": "..."} on Loki unreachable or invalid query.

Query SMART health for a storage device via smartctl.

device: /dev/nvme0n1, /dev/sda, etc. Default is niborserver's NVMe. Returns: overall_health, critical_warning, temperature_c, available_spare_pct, percentage_used_pct, power_on_hours, unsafe_shutdowns, media_errors.

Requires sudo (smartctl needs raw device access). Returns {"error": ...} if smartctl isn't installed or sudo isn't permitted (the calling user must have NOPASSWD sudo for smartctl OR the MCP server must run as root).

Report on the niborserver backup pipeline's last run.

Reads /var/log/niborserver-backup.log and reports: last_run_started, last_run_completed, last_run_duration_seconds, last_run_size, last_run_succeeded.

Returns {"error": ...} if the log doesn't exist (backup not yet run).

Execute a Flux query against the local InfluxDB and return parsed records.

flux: Flux query string. The bucket is NOT auto-substituted — include from(bucket:"<bucket>") |> range(start: -1h) |> ... yourself. bucket: name surfaced in the response for context (does not modify the query).

Reads InfluxDB URL from config (influxdb.url, default localhost:8086) and the org + token from the env vars named in influxdb.org_env / influxdb.token_env (default INFLUXDB_ORG / INFLUXDB_TOKEN).

Returns: {bucket, row_count, columns, records (list of dicts), truncated_at}. Records are capped at 500 rows to keep Claude's context manageable; if more were returned, truncated_at: 500 appears in the response.

Returns {"error": "..."} on missing token, network failure, or Flux syntax error.
