## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

- **Supply Chain Security**: 100/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - No install/post-install scripts declared.
  - No production dependencies, so there is no dependency health to assess.
- **Provenance & Transparency**: 19/100
  - Repository check failed: the declared repository URL returned HTTP 404.
  - Provenance check failed: no build-provenance attestation is published.
  - Clear OSI-approved license (MIT).

  - Security-disclosure policy not yet verified: we couldn't inspect the source repository.
- **Schema Quality & AI Usability**: 52/100
  - AI-judged instruction clarity (fair).
  - Context-footprint check failed: tool/resource definitions use about 426 tokens (~213/item across 2 items; 2 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 37/100
  - Stability observed for 11 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 86/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 57% of tool parameters carry a description.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (2)

### `extract_to_schema` (~283 tokens)

Turn messy text/HTML into guaranteed schema-valid JSON. Output is guaranteed to validate against your JSON Schema (Ajv, draft 2020-12) or you get a typed error and are not charged (charge-only-on-success). Evaluation mode: calls the legacy V1 endpoint with a small free allowance (no wallet configured). Set SCHEMASURE_PRIVATE_KEY to enable paid production calls via x402 V2. Benchmarked 100% schema-valid with ~0.99 field F1 and zero hallucinations across a 10-doc-type corpus (11 items, incl. an adversarial prompt-injection tier), p50 latency ~1.5s. Evidence: /.well-known/benchmarks.json. Use whenever you need unstructured text/HTML turned into JSON matching a specific shape — invoices, receipts, resumes, product/HTML pages, logs, or anything you can describe as a schema. Tip: add a per-field description to your schema for best accuracy.

Input parameters:

- `input` (string, required): Raw unstructured content to extract from (plain text or HTML).
- `inputType` (string): How to interpret `input`: plain text, HTML, or auto-detect (default).
- `options` (object)
- `schema` (object, required): JSON Schema (draft 2020-12) that the returned `data` is guaranteed to satisfy.

### `extract_image_to_schema` (~143 tokens)

Extract readable fields from a PNG, JPEG, or WebP invoice, receipt, form, screenshot, label, or photographed document into guaranteed schema-valid JSON. This hosted service is V2-only and always paid from the first call; there is no free or V1 image endpoint. A locally configured SCHEMASURE_PRIVATE_KEY signs x402 V2 USDC payments on Base mainnet and never leaves this process. Add per-field schema descriptions for best accuracy.

Input parameters:

- `image` (object, required)
- `options` (object)
- `schema` (object, required): JSON Schema (draft 2020-12) that the returned `data` is guaranteed to satisfy.
