| name | mineru-extract |
| description | Use the official MinerU (mineru.net) parsing API to convert a URL (HTML pages like WeChat articles, or direct PDF/Office/image links) into clean Markdown + structured outputs. Use when web_fetch/browser can’t access or extracts messy content, and you want higher-fidelity parsing (layout/table/formula/OCR). |
MinerU 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 }
- 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):
MINERU_TOKEN=***
MINERU_API_BASE=https://mineru.net
2) Parse URL(s) → Markdown (recommended)
MCP-style wrapper (returns JSON, optionally includes markdown text):
python3 skills/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 skills/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 skills/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:
/home/node/.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 requires MinerU-HTML)--ocr/--no-ocr: enable OCR (effective for pipeline/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_msg and keep an original-source link in outputs.
