Skill for Claude Code

Written for Claude Code: installed under .claude/.

This is AvatarGanymede/MinerU-MCP's own configuration. It tells Claude Code how to work on MinerU-MCP itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything MinerU-MCP configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is unzip -o ./temp/report.zip -d ./temp/report.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

convert-to-markdown scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Document to Markdown Conversion

Convert documents to Markdown using the mineru-converter MCP tools. Supports URLs and local file paths. The server auto-detects file type and configures optimal settings (model, OCR, etc.).

MCP Tools Reference

Primary tool — use this by default

  • convert_to_markdown — Complete workflow: submit → poll → download. Parameters:
    • url (required): URL or local file path
    • output_path (required): local path to save the result zip (e.g., ./temp/report.zip)
    • model_version (optional, default "vlm"): auto-detected; "MinerU-HTML" for HTML files
    • max_wait_seconds (optional, default 300): increase for large documents (e.g., 600 for 100+ page PDFs)
    • poll_interval (optional, default 10)
    • convert_pdf_to_markdown is an identical alias

Step-by-step tools — use when finer control is needed

  1. create_parse_task — Submit a parsing task. Extra parameters:

    • is_ocr (default false): force OCR on; auto-enabled for images
    • enable_formula (default true): formula recognition
    • enable_table (default true): table recognition
    • Returns task_id (URL input) or batch_id (local file input)

  2. get_task_status — Poll task progress. Pass task_id or batch_id.

  3. download_result — Download the result zip. Parameters: zip_url, output_path.

Use step-by-step tools when the user needs to: disable formula/table recognition, force OCR, submit multiple tasks in parallel, or check a previously submitted task.

Workflow

1. Determine output path

  • If the user provided an output path, use it (ensure it ends in .zip).
  • Otherwise, derive from the filename: ./temp/<filename_without_ext>.zip
    • URL example: https://example.com/report.pdf → ./temp/report.zip
    • Local example: C:\docs\slides.pptx → ./temp/slides.zip

2. Call convert_to_markdown

Pass url (the URL or local file path as-is) and output_path. The server handles:

  • Local file upload via batch API automatically
  • HTML → MinerU-HTML model, images → OCR enabled
  • Large PDFs: >600 pages uses page ranges; >200MB splits the file into chunks
  • Polling until completion or timeout

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
