Schema Quality & AI Usability71
  • AI-judged instruction clarity (good).Pass
  • Context-footprint check failed: tool/resource definitions use about 1014 tokens (~126/item across 8 items; 8 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail

Install

How do I install the MinerU MCP server?

MinerU runs locally as an npm package, launched with npx -y mineru-mcp. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

MCP tools · 8 exposed · ~1,014 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. 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 →

Tool Tokens
mineru_batch ~137

Parse multiple URLs in one batch (max 200). Preferred over mineru_upload_batch — faster and more reliable. Use public URLs (arXiv, SSRN, publisher sites) when available.

NameTypeReqDescription
formatsarray–Extra export formats
formulaboolean–Formula recognition
languagestring–Language code: ch, en, etc
modelstring–pipeline=fast, vlm=90% accuracy
ocrboolean–Enable OCR (pipeline only)
tableboolean–Table recognition
urls–yesArray of document URLs, or a single URL string

No output schema declared.

No examples provided.

mineru_batch_status ~65

Get batch results. Supports pagination for large batches.

NameTypeReqDescription
batch_idstringyesBatch ID from mineru_batch
formatstring–Output format
limitnumber–Max results to return
offsetnumber–Skip first N results

No output schema declared.

No examples provided.

mineru_download_results ~95

Download batch results and extract named paper folders. Each folder contains {name}.md, {name}_content.json (structured TOC), and images/. Output includes parsed title — verify it matches the expected paper.

NameTypeReqDescription
batch_idstringyesBatch ID from mineru_upload_batch or mineru_batch
output_dirstringyesDirectory to save markdown files
overwriteboolean–Overwrite existing files

No output schema declared.

No examples provided.

mineru_merge_slices ~130

Stitch the slices of a mineru_parse_long batch into one {name}/{name}.md (+ {name}_content.json with page_idx re-based to the whole document, + images/). Slices are ordered by their page range; each is marked with an HTML comment. Waits for nothing — if any slice is still processing, it reports and you re-run later.

NameTypeReqDescription
batch_idstringyesBatch ID from mineru_parse_long
output_dirstringyesDirectory to write the merged document folder into
overwriteboolean–Overwrite an existing merged folder

No output schema declared.

No examples provided.

mineru_parse ~132

Parse a document URL. Returns task_id to check status.

NameTypeReqDescription
formatsarray–Extra export formats
formulaboolean–Formula recognition
languagestring–Language code: ch, en, etc
modelstring–pipeline=fast, vlm=90% accuracy
ocrboolean–Enable OCR (pipeline only)
pagesstring–Page range: 1-10,15 or 2--2
tableboolean–Table recognition
urlstringyesDocument URL (PDF, DOC, PPT, images)

No output schema declared.

No examples provided.

mineru_parse_long ~257

Parse a document LONGER than 200 pages (MinerU's per-file cap) by submitting it as one batch of ≤200-page slices with page_ranges. Give total_pages (from `mdls -name kMDItemNumberOfPages`, `pdfinfo`, or the viewer) — it is auto-detected only for local files on macOS. Returns a batch_id; poll with mineru_batch_status, then stitch with mineru_merge_slices. Files ≤200 pages: use mineru_parse instead.

NameTypeReqDescription
filestring–Absolute local file path (uploaded once per slice — slow for big files)
formulaboolean–Formula recognition
languagestring–Language code: ch, en, etc
modelstring–pipeline=fast, vlm=90% accuracy
namestring–Output name for the merged result (default: from URL/file name)
ocrboolean–Enable OCR (pipeline only)
slice_sizeinteger–Pages per slice (≤200)
tableboolean–Table recognition
total_pagesinteger–Total page count of the document
urlstring–Public document URL (preferred)

No output schema declared.

No examples provided.

mineru_status ~42

Check task progress. Returns download URL when done.

NameTypeReqDescription
formatstring–Output format
task_idstringyesTask ID from mineru_parse

No output schema declared.

No examples provided.

mineru_upload_batch ~156

Upload local files for batch parsing. SLOW: uploads can take minutes and may timeout. Prefer mineru_batch with public URLs (arXiv, SSRN, publisher sites) when available — it's faster and more reliable. Only use this for files not available online.

NameTypeReqDescription
directorystring–Directory path containing PDF/DOC/PPT files
files––Array of absolute file paths, or a single path string
formatsarray–Extra export formats
formulaboolean–Formula recognition
languagestring–Language code: ch, en, etc
modelstring–pipeline=fast, vlm=90% accuracy
tableboolean–Table recognition

Common questions

What is the MinerU MCP server?

MinerU is an MCP server listed in the public MCP registry as io.github.linxule/mineru. MinerU document parsing API, PDFs, images, DOCX, PPTX with OCR and batch processing. This page covers its npm package (mineru-mcp).

Is the MinerU MCP server safe to use?

MinerU scores 91 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 20 September 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the MinerU MCP server expose?

MinerU exposes 8 tools: mineru_parse, mineru_status, mineru_batch, mineru_batch_status, mineru_upload_batch, and 3 more. Their descriptions and schemas cost roughly 1,014 tokens of context every time the server is loaded.

Is the MinerU MCP server still maintained?

MinerU is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

What licence is the MinerU MCP server under?

MinerU declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
