About mineru-extract
mineru-extract is a skill that uses the official MinerU API to turn URLs or files into Markdown. It submits jobs, polls for completion, and downloads results, with JSON summaries or inline Markdown output; it does not run an MCP server.
Key features
- 01Submit multiple URLs and poll parse jobs
- 02Download result archives and extract Markdown
- 03Summarize successful items and errors as JSON
- 04Offer OCR, table, and formula options
- 05Choose a default model based on file type
Use cases
- 01Convert web articles to Markdown
- 02Parse PDFs, presentations, or image documents
- 03Process multiple document sources in batches
- 04Inspect failed URLs and parsing errors
MCP support
The project follows the MinerU MCP usage model but explicitly does not run an MCP server. Its scripts call the official MinerU API and return results as JSON or Markdown.
Install
Copy the command and run it in a terminal.

From the project READMEMinerU Extract (official API)
Use MinerU as an upstream “content normalizer”: submit a URL to MinerU, poll for completion, download the result zip, and extract the main Markdown.
Quick start (MCP-aligned)
We align to the MinerU MCP mental model, but we do not run an MCP server.
- Primary script (MCP-style):
scripts/mineru_parse_documents.py- Input:
--file-sources(comma/newline-separated) - Output: JSON contract on stdout:
{ ok, items, errors }
- Input:
- Low-level script (single URL):
scripts/mineru_extract.py
Auth:
- Set
MINERU_TOKEN(Bearer token from mineru.net)
Default model heuristic:
- URLs ending with
.pdf/.doc/.ppt/.png/.jpg→pipeline - Otherwise →
MinerU-HTML(best for HTML pages like WeChat articles)
1) Configure token (skill-local)
Put secrets in skill root .env (do not paste into chat outputs):
# In the mineru-extract skill directory: .env
MINERU_TOKEN=your_token_here
MINERU_API_BASE=https://mineru.net
2) Parse URL(s) → Markdown (recommended)
MCP-style wrapper (returns JSON, optionally includes markdown text):
python3 mineru-extract/scripts/mineru_parse_documents.py \
--file-sources "<URL1>\n<URL2>" \
--language ch \
--enable-ocr \
--model-version MinerU-HTML
If you want the markdown content inline in the JSON (can be large):
python3 mineru-extract/scripts/mineru_parse_documents.py \
--file-sources "<URL>" \
--model-version MinerU-HTML \
--emit-markdown --max-chars 20000
Low-level (single URL, print markdown to stdout):
python3 mineru-extract/scripts/mineru_extract.py "<URL>" --model MinerU-HTML --print > /tmp/out.md
Output
The script always downloads + extracts the MinerU result zip to:
~/.openclaw/workspace/mineru/<task_id>/
It writes:
result.zip- extracted files (Markdown + JSON + assets)
It prints a JSON summary to stderr with paths:
task_id,full_zip_url,out_dir,markdown_path
Parameters (common)
--model:pipeline | vlm | MinerU-HTML(HTML requiresMinerU-HTML)--ocr/--no-ocr: enable OCR (effective forpipeline/vlm)--table/--no-table: table recognition--formula/--no-formula: formula recognition--language ch|en|...--page-ranges "2,4-6"(non-HTML)--timeout 600/--poll-interval 2
Failure modes & fallbacks
- MinerU may fail to fetch some URLs (anti-bot / geo / login).
- Fallback: provide an HTML file or a PDF/long screenshot; then implement “upload + parse” flow with MinerU batch upload endpoints.
- Always report the failing URL + MinerU
err_msgand keep an original-source link in outputs.
