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 Security86
  • No malware found by supply-chain analysis.Pass
  • Only part of the dependency tree could be resolved (94 of 98), so this covers what we could see, not the whole tree.Partial
  • No install/post-install scripts declared.Pass
  • Only part of the dependency tree could be resolved (94 of 98), so this covers what we could see, not the whole tree. View diagnostics → Partial
Provenance & Transparency45
Schema Quality & AI Usability77
  • AI-judged instruction clarity (excellent).Pass
  • Tool/resource definitions use about 487 tokens (~97/item across 5 items; 5 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 — 5 exposed · ~487 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
diff_schemas ~83

Compare two JSON Schemas and identify all differences: added/removed/changed fields, type changes, constraint changes (min/max, patterns, enums). Classifies each change as breaking or non-breaking for backwards compatibility analysis.

NameTypeReqDescription
new_schemaobjectyesThe updated (new) JSON Schema
old_schemaobjectyesThe original (old) JSON Schema

No output schema declared.

No examples provided.

generate_json_schema ~113

Generate a JSON Schema from one or more sample JSON values. Infers types, required fields, formats (email, date, URI, UUID), and detects enum patterns from multiple examples.

NameTypeReqDescription
detect_enumsbooleanWhether to detect enum values from string fields across samples (default: true, requires >= 3 samples)
samplesarrayyesArray of sample JSON values to infer the schema from. More samples produce a more accurate schema.
titlestringOptional title for the generated schema

No output schema declared.

No examples provided.

generate_typescript ~104

Generate TypeScript interfaces and types from JSON data or a JSON Schema. Handles nested objects, arrays, optional fields, enums, union types, and Record types.

NameTypeReqDescription
jsonSample JSON data to convert to TypeScript types. Provide either this or 'schema'.
root_namestringName for the root interface/type (default: 'Root')
schemaobjectA JSON Schema to convert to TypeScript types. Provide either this or 'json'.

No output schema declared.

No examples provided.

mock_from_schema ~119

Generate realistic mock data from a JSON Schema. Uses smart field-name detection to produce contextual values: email fields get valid emails, name fields get realistic names, dates get ISO strings, etc. Supports all JSON Schema types and constraints.

NameTypeReqDescription
countnumberNumber of mock objects to generate (default: 1). If > 1, returns an array.
schemaobjectyesThe JSON Schema to generate mock data from
seednumberRandom seed for reproducible output. Same seed + same schema = same data.

No output schema declared.

No examples provided.

validate_schema ~68

Validate data against a JSON Schema. Returns detailed error messages with JSON path, expected type, actual value, and the violated keyword (type, required, format, pattern, minimum, etc.).

NameTypeReqDescription
