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 → Why this is hard to score →
Supply Chain Security100
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- No install/post-install scripts declared.Pass
- No production dependencies, so there is no dependency health to assess. View diagnostics → Pass
Provenance & Transparency45
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 7 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability70
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 272 tokens (~272/item across 1 items; 1 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management70
- Stability observed for 21 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
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
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 1 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 1 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

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. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
extract_units ~272
Extract every quantity — a number with a unit — from a document, with the text as written and its value in one base unit: durations in milliseconds, sizes in bytes, percentages as a ratio, frequencies in hertz. Parses JSON, YAML, CSV, TOML, INI and dotenv; anything else is scanned as text, so a format is optional. A quantity it cannot resolve — a bare `m`, a fractional `1.5KB`, a locale-shaped `1,5s`, an expression like `1h + 30m`, an SI byte multiple that may have meant the binary one — is returned with a named reason instead of a guess. A bare number with no unit is not a finding.
| Name | Type | Req | Description |
|---|---|---|---|
| content | string | yes | The document text to scan. |
| dimension | string | – | Report only one dimension. A refusal that names no dimension is always kept, because it could have been the one asked for. |
| filename | string | – | Filename used to infer the format when `format` is absent, e.g. "config.toml". |
| format | string | – | Document format. Optional — an unrecognised or absent format scans the text directly. |
| maxResults | integer | – | Cap on returned quantities (default 500). meta.truncated reports whether any were dropped. |
