Available components
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 Security94
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- Runs a script at install time (build_backend,cmdclass) that we could not recognise. It may be perfectly ordinary, but we do not read the published tarball, so we cannot say what it does. View diagnostics → Partial
- 1 of 36 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency32
- 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
- License check failed: no license is declared. See how to fix → Fail
- Actively maintained (last published 161 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability58
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1183 tokens (~591/item across 2 items; 2 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 Management83
- Stability observed for 25 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
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass

No change was recorded against any check on this day. Stability & Change Management went from 80 to 83. That category is still filling its 30-day observation window: 24 days of observed history at the previous scan, 25 at this one. The score rises as the window fills, whether or not the server changes.

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 →
get_ocr_languages Get Ocr Languages ~19
List all OCR languages supported by MinerU.
Input schema present but exposes no named parameters.
Structured output declared, but exposes no named fields.
No examples provided.
parse_documents Parse Documents ~487
High-quality document parsing: converts PDF, Word, PPT, Excel (in Flash Mode), and images to Markdown. Powered by SOTA MinerU PDF extraction — supports full document parsing (200+ pages), academic paper parsing, formula recognition, table extraction, multi-column layouts, scanned document OCR, and webpage-to-Markdown conversion. Designed for AI workflows. Unlike basic readers limited to the first 10 pages, MinerU processes entire documents end-to-end.
| Name | Type | Req | Description |
|---|---|---|---|
| enable_ocr | – | – | OCR mode: null (default) - auto-detect: the server decides whether OCR is needed. true - force OCR on when the user mentions poor scan quality. false - disable OCR. Omit this… |
| file_sources | array | yes | Files to parse. Each entry is either: - a plain string: a local file path or URL - a dict {"source": "...", "pages": "N-M"}: with an optional page range Page range: "N" (single page) or "N-M" (fo… |
| language | – | – | OCR language code. Omit if unknown; the server defaults to "ch" (Chinese + English). Infer from the document filename when possible, for example "manual_en.pdf" -> "en". Common codes: "ch", "en", "ja… |
| model | – | – | Parsing model. Set to "html" only when all file_sources are web page URLs. Otherwise omit it and let MinerU auto-select the appropriate model. Ignored in Flash mode. |
| output_dir | – | – | Directory used when parsed results need to be saved locally, such as batch parsing or oversized inline content. Defaults to the server-configured directory. |
Structured output declared, but exposes no named fields.
