Convert PDFs, Word (DOCX), PowerPoint (PPTX), Excel (XLSX in Flash mode), images, and public document URLs—or HTML page URLs—into Markdown using the MinerU cloud API. **World effects:** Reads local paths you pass; fetches http(s) URLs. Uploads file or URL content to mineru.net for processing (do not use for data you must not send off-device). Does not modify or delete originals. May write Markdown (and sometimes images) under `output_dir` or the server default when results are saved or inline content is too large. **Auth & limits:** Without `MINERU_API_TOKEN`, uses free Flash mode: Markdown-only output, service limits apply. With `MINERU_API_TOKEN`, higher per-file page limits and optional extra output formats per MinerU plans; token is read from env (or HTTP Bearer when using streamable HTTP). **Use this when:** The user needs full-document extraction, tables/formulas as HTML/Latexa, batch conversion, or per-file PDF page ranges. **Do not use** for listing supported OCR script codes—call `get_ocr_languages` instead. **Not a substitute** for offline-only or strictly local parsers. **Parameters (intent):** `file_sources` is a list of path/URL strings or `{"source": "…", "pages": "1-5"}` objects (PDF page ranges; Flash allows simple `N` or `N-M`). `enable_ocr` defaults to true. `language` is an OCR/script code (default `ch`); see `get_ocr_languages` for valid values. Set `model` to `"html"` only when every source is a web page URL; otherwise omit. `output_dir` overrides where large or batch results are written.

Return the supported MinerU OCR / script language codes (e.g. ch, en, japan, latin). Read-only; no uploads. Use before setting `language` on `parse_documents` for scanned or multilingual documents. Do not use for converting files—call `parse_documents` instead.

An API token (MINERU_API_TOKEN) is required for Precision mode. Flash mode does not require a token.

How many OCR languages are supported?

OCR supports 109 languages. You can list them using the get_ocr_languages tool.

Which MCP clients are compatible?

Mineru Open Mcp works with Claude Desktop, Cursor, Windsurf, and other MCP-compatible clients.
