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 Security81
- No malware found by supply-chain analysis.Pass
- CVE check failed: a known high-severity CVE affects @modelcontextprotocol/sdk 1.29.0, a direct dependency. A fixed version is available. View diagnostics → Fail
- No install/post-install scripts declared.Pass
- 33 of 105 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency97
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to linxule/mineru-mcp). View diagnostics → Pass
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 49 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
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
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management77
- Stability observed for 23 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
Tool Safety75
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "mineru_merge_slices" implies "merge" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail
- An AI judge read all 8 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

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 →
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.
| Name | Type | Req | Description |
|---|---|---|---|
| formats | array | – | Extra export formats |
| formula | boolean | – | Formula recognition |
| language | string | – | Language code: ch, en, etc |
| model | string | – | pipeline=fast, vlm=90% accuracy |
| ocr | boolean | – | Enable OCR (pipeline only) |
| table | boolean | – | Table recognition |
| urls | – | yes | Array 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.
| Name | Type | Req | Description |
|---|---|---|---|
| batch_id | string | yes | Batch ID from mineru_batch |
| format | string | – | Output format |
| limit | number | – | Max results to return |
| offset | number | – | 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.
| Name | Type | Req | Description |
|---|---|---|---|
| batch_id | string | yes | Batch ID from mineru_upload_batch or mineru_batch |
| output_dir | string | yes | Directory to save markdown files |
| overwrite | boolean | – | 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.
| Name | Type | Req | Description |
|---|---|---|---|
| batch_id | string | yes | Batch ID from mineru_parse_long |
| output_dir | string | yes | Directory to write the merged document folder into |
| overwrite | boolean | – | 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.
| Name | Type | Req | Description |
|---|---|---|---|
| formats | array | – | Extra export formats |
| formula | boolean | – | Formula recognition |
| language | string | – | Language code: ch, en, etc |
| model | string | – | pipeline=fast, vlm=90% accuracy |
| ocr | boolean | – | Enable OCR (pipeline only) |
| pages | string | – | Page range: 1-10,15 or 2--2 |
| table | boolean | – | Table recognition |
| url | string | yes | Document 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.
| Name | Type | Req | Description |
|---|---|---|---|
| file | string | – | Absolute local file path (uploaded once per slice — slow for big files) |
| formula | boolean | – | Formula recognition |
| language | string | – | Language code: ch, en, etc |
| model | string | – | pipeline=fast, vlm=90% accuracy |
| name | string | – | Output name for the merged result (default: from URL/file name) |
| ocr | boolean | – | Enable OCR (pipeline only) |
| slice_size | integer | – | Pages per slice (≤200) |
| table | boolean | – | Table recognition |
| total_pages | integer | – | Total page count of the document |
| url | string | – | Public document URL (preferred) |
No output schema declared.
No examples provided.
mineru_status ~42
Check task progress. Returns download URL when done.

| task_id | string | yes | Task 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.
| Name | Type | Req | Description |
|---|---|---|---|
| directory | string | – | Directory path containing PDF/DOC/PPT files |
| files | – | – | Array of absolute file paths, or a single path string |
| formats | array | – | Extra export formats |
| formula | boolean | – | Formula recognition |
| language | string | – | Language code: ch, en, etc |
| model | string | – | pipeline=fast, vlm=90% accuracy |
| table | boolean | – | Table recognition |
No output schema declared.

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 5 November 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.
