docling-rs-mcp
A Model Context Protocol server that
converts documents to Markdown for AI agents — PDF with layout analysis,
table structure and OCR, DOCX, PPTX, XLSX, HTML, EPUB, e-mail, scans and
40-odd other formats. It is docling.rs,
a Rust port of IBM's docling,
and it serves MarkItDown's convert_to_markdown(uri) tool under the same
name and contract: a markitdown-mcp setup switches by changing the command.
uvx docling-rs-mcp --root ~/Documents
Claude Desktop (claude_desktop_config.json):
{
"mcpServers": {
"docling": { "command": "uvx", "args": ["docling-rs-mcp", "--root", "/Users/me/Documents"] }
}
}
Claude Code: claude mcp add docling -- uvx docling-rs-mcp --root ~/Documents.
Tools
| Tool | Returns |
|---|---|
convert_to_markdown(uri) |
Markdown of the document behind an http:/https:/file:/data: URI or a path |
convert(uri, to?, images?, options?) |
md, json (docling's DoclingDocument), html, text, latex, chunks, vtt or pandoc, with docling.rs's conversion options — {"pages": "1-5"}, {"ocr_lang": "ch"}, {"password": "…"}, … |
list_input_formats() |
the extensions the server converts |
PDF models
Office, HTML, Markdown and e-mail need no models. PDFs and images use ONNX models for layout, tables and OCR (~720 MB). Fetch them once:
uvx docling-rs-mcp --download-models
They land in the docling.rs cache ($DOCLING_RS_CACHE_DIR, else
~/.cache/docling.rs) and the server finds them from then on;
--download-models=all adds the code/formula enrichment models (~740 MB
more). Until then PDFs convert from their text layer, as MarkItDown's do.
macOS: PyPI has no macOS wheel of docling-rs yet, so uv builds it from
source on first use — install a Rust toolchain (rustup) and run the
--download-models line in a terminal once; the build is cached, and an MCP
client then starts the server without waiting for it.
What a call may reach
Local paths and file: URIs are confined to --root (repeatable; the
working directory by default, except in /, where it is required).
http(s) URLs are fetched only with
--allow-url-fetch, and private or loopback addresses stay blocked.
--http serves Streamable HTTP on 127.0.0.1:3001 instead of stdio.
--help lists every flag; the security model is in
docs/SECURITY.md.
The same server ships in the docling-rs binary (docling-rs mcp) and the
ghcr.io/docling-project/docling-rs image, models included; with the
docling-rs Python package installed it is also python -m docling_rs.mcp.
On NVIDIA GPUs, uv run --with docling-rs-cuda python -m docling_rs.mcp.
