## 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)

## MCP tools (4)

### `pdf_compare` (~71 tokens)

Compare two local PDFs at text and page level and report changed pages and terms.

Input parameters:

- `after` (string, required): Local PDF path for the after document.
- `before` (string, required): Local PDF path for the before document.
- `context_chars` (integer|null)
- `max_file_bytes` (integer|null)

### `pdf_evidence` (~161 tokens)

Focused PDF evidence operations. Pure-Rust supports inspect, bounded page rendering/crops, opt-in bounded command-provider OCR, and region analysis via command, HTTP URL, or ollama/openai-compatible/lmstudio/llamacpp presets.

Input parameters:

- `include_image` (boolean|null)
- `include_metadata` (boolean|null)
- `languages` (array|null)
- `max_output_chars` (integer|null)
- `max_pages` (integer|null)

- `operation` (required)
- `sample_pages` (integer|null)
- `scale` (number|null)
- `sources` (array, required)
- `timeout_ms` (integer|null)

### `read_pdf` (~545 tokens)

Read a PDF. Sources only uses the fast preset: markdown, tables, chunks, document map, page geometry, layout, and semantic hints. No OCR and no trust audit. profile quality adds structure; profile research adds safety, trust, and accessibility. OCR and rendering stay on pdf_evidence or include_ocr_text_layer.

Input parameters:

- `auto` (boolean|null): Legacy preset switch. true selects balanced (fast plus safety, trust, and accessibility) when profile and auto_detail are omitted. Omit it to use fast. false keeps manual control. auto_detail wins ov…
- `auto_detail`: Depth switch that wins over profile: fast, balanced, or full. full adds structure and audits. Never enables OCR or rendering.
- `include_accessibility_report` (boolean|null)
- `include_annotations` (boolean|null)
- `include_attachments` (boolean|null)
- `include_chunks` (boolean|null)
- `include_document_ast` (boolean|null)

- `include_visual_enrichments` (boolean|null)
- `max_visual_enrichments` (integer|null)
- `profile` (string|null): Named preset: fast (default), quality (structure, no audits, no OCR), or research (quality plus safety, trust, and accessibility). Ignored when auto is false or any include_* flag is set.
- `sample_pages` (integer|null): Not used by read_pdf presets, which read every requested page. Sampling belongs to pdf_evidence inspect. Limit a read with sources[].pages.
- `sources` (array, required)
- `trust_report_redaction`

### `search_pdf` (~137 tokens)

Searches extracted PDF text with page, snippet, geometry, and provenance. Optional OCR uses the bounded command provider.
