Trust breakdown (6 categories)

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score →

Supply Chain Security83
  • No malware found by supply-chain analysis.Pass
  • CVE check failed: a known medium-severity CVE affects hono 4.12.33, reached via @modelcontextprotocol/sdk > hono. A fixed version is available. View diagnostics → Fail
  • No install/post-install scripts declared.Pass
  • Only part of the dependency tree could be resolved (95 of 99), so this covers what we could see, not the whole tree. View diagnostics → Partial
Provenance & Transparency45
Schema Quality & AI Usability83
  • AI-judged instruction clarity (excellent).Pass
  • Tool/resource definitions use about 410 tokens (~102/item across 4 items; 4 tools + 0 resources), lean.Pass
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management0
  • Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage100
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 100% of tool parameters carry a description.Pass
Capabilities100
  • Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

Unverified: 1 category

A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

MCP tools — 4 exposed · ~410 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability.

Tool Tokens
cron_presets ~73

Return a library of common cron expression presets (every 5 min, hourly, daily at midnight, weekdays 9am, monthly, quarterly, yearly, etc.) with their plain-English labels. Use this when a user asks for a "common" or "standard" schedule and you want to offer proven starting points.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

next_runs ~103

Compute the next N scheduled run times for a cron expression. Returns ISO-8601 timestamps with relative offsets (+5m, +1h, +2d). Use this to preview when a job will actually fire before committing it.

NameTypeReqDescription
countnumber—How many future runs to compute (default 5, max 50).
expressionstringyesThe cron expression.
fromstring—ISO-8601 start time (defaults to now).

No output schema declared.

No examples provided.

parse_cron ~117

Parse a cron expression and return a human-readable description of when it fires. Supports 5-field standard cron (min hour dom month dow) plus extensions: L (last day/weekday), W (nearest weekday), # (nth weekday), and named months/days (JAN..DEC, SUN..SAT). Use this to explain any cron schedule in plain English.

NameTypeReqDescription
expressionstringyesThe cron expression to parse, e.g. "*/5 * * * *" or "0 9 * * 1-5".

No output schema declared.

No examples provided.

validate_cron ~117

Deeply validate a cron expression for correctness and common mistakes. Catches: impossible schedules (e.g. day 31 in Feb), OR-semantics gotchas (dom AND dow both restricted = either matches, not both), midnight scheduling spikes, uneven step values (*/7), leap-year edge cases, weekday-only warnings, and more. Returns warnings, observations, optimization suggestions, and an estimated yearly run count. Use this BEFORE deploying a cron job to catch silent failures.

NameTypeReqDescription
expressionstringyesThe cron expression to validate.

No output schema declared.

No examples provided.
