anymd

PDF, Word, PowerPoint, Excel, EPUB, HTML and web pages, images (OCR), audio and video (metadata, subtitles, transcripts). A fast Rust MCP server and CLI that runs on your machine. No API key.

anymd is the free, local mode of the same crates that run Sylphx AI parse, the hosted document-parse service: the same crates, hosted and metered per page for callers that want no local runtime.

Formerly pdf-reader-mcp. Migrating from pdf-reader-mcp

A real, unedited terminal recording (asciinema + agg, script). The last command is Claude Code answering from the PDF through the anymd MCP server.

npx -y @sylphx/anymd setup              # add anymd to every MCP client on this machine
npx -y @sylphx/anymd report.pdf > report.md   # or convert from the shell

Why anymd

• Fast. Native Rust converts in parallel, page by page. On the 38 benchmark documents, anymd takes 11.5 s in total; docling 2,432.4 s (212×), markitdown 75.6 s (7×); marker converted 30 of them in 7,104.5 s, against anymd's 4.64 s on the same 30 (1,532×).

• Accurate. A layout engine rebuilds words from glyph gaps, puts two-column papers in reading order, and recovers tables, including borderless ones. The text stays exactly as printed, with no glued words and no scrambled columns.
• Lean on tokens. Pages come back as Markdown with <!-- page 3 --> citation anchors, a small front-matter header, and compact tables. A token budget and a cursor keep large documents within your agent's context.
• Every format, one call. One tool reads every format listed below. It also accepts web URLs and whole directories, and search looks across all of them.
• Local and private. Nothing is uploaded. OCR uses installed local doc-VLM models or tesseract; transcripts use ffmpeg and bundled Qwen3-ASR. OCR setup and ASR model downloads require explicit opt-in.

Install

Add anymd to every MCP client on your machine (Claude Code, Codex, Cursor, VS Code, Claude Desktop, Windsurf, Gemini CLI) with one command:

npx -y @sylphx/anymd setup     # --dry-run to preview, --remove to undo

Or add it by hand: every MCP client runs the same command, npx -y @sylphx/anymd. Node 18+ is the only requirement; npm installs the native binary for your platform.

claude mcp add anymd -- npx -y @sylphx/anymd

Or as a plugin, with the anymd skill: /plugin marketplace add SylphxAI/anymd, then /plugin install anymd@anymd.

codex mcp add anymd -- npx -y @sylphx/anymd

or in ~/.codex/config.toml:

[mcp_servers.anymd]
command = "npx"
args = ["-y", "@sylphx/anymd"]

[Add to Cursor]

or in .cursor/mcp.json:

{ "mcpServers": { "anymd": { "command": "npx", "args": ["-y", "@sylphx/anymd"] } } }

Install in VS Code with one click, or from a terminal:

code --add-mcp '{"name":"anymd","command":"npx","args":["-y","@sylphx/anymd"]}'

or in .vscode/mcp.json:

{ "servers": { "anymd": { "type": "stdio", "command": "npx", "args": ["-y", "@sylphx/anymd"] } } }

One click: download anymd-<version>.mcpb from the latest release and open it. Or, by hand:

Add to claude_desktop_config.json (Settings → Developer → Edit Config):

{ "mcpServers": { "anymd": { "command": "npx", "args": ["-y", "@sylphx/anymd"] } } }

Any client that speaks MCP over stdio: command npx, args ["-y", "@sylphx/anymd"]. To keep the server inside one folder, add --allow-dir=/path/to/docs.

npm install -g @sylphx/anymd     # or run it once with: npx -y @sylphx/anymd <file>

Python wheels carry the same prebuilt binary and are on PyPI as anymd from the first release after publication.

Windows: winget install Sylphx.anymd. macOS and Linux: brew install sylphxai/tap/anymd. Scoop: scoop bucket add sylphx https://github.com/SylphxAI/scoop-bucket && scoop install anymd.

Docker (amd64 and arm64):

docker run --rm -v "$PWD:/data" ghcr.io/sylphxai/anymd report.pdf > report.md
docker run -i --rm ghcr.io/sylphxai/anymd        # MCP server on stdio

Or build it from crates.io (Rust 1.95+, CMake and a C++ compiler; doc-VLM OCR and local ASR are included):

cargo install anymd

npm, pip and Docker ship a prebuilt binary, while cargo install compiles one on your machine.

Benchmarks

AgentDocBench is an open benchmark for document → Markdown conversion for agents: license-clean documents in 12 categories (math papers, two-column papers, financial tables, forms, scans, CJK, slides, spreadsheets, Word, EPUB, HTML), scored on verbatim sentences, text F1, reading order, and table cells, with time and output tokens. Every tool runs on the same kind of GitHub-hosted runner (4 CPUs):

	anymd	docling	kreuzberg	unstructured	markitdown	marker	pdftotext
Overall score	96.4	93.0	81.7	81.2	76.8	71.0	42.2
Table cells F1	92.2	89.9	38.4	38.4	57.2	60.9	0.0
Reading order	98.8	94.4	96.8	93.9	85.5	76.8	52.0
Docs converted	38/38	38/38	38/38	38/38	38/38	30/38	23/38
Time, all docs	11.5 s	2,432.4 s	16.0 s	346.5 s	75.6 s	7,104.5 s	0.90 s

The generated leaderboard, per-category scores (including where anymd loses), and method are in the benchmark guide. The corpus, ground truth, adapters, and raw results are in bench/, and the Benchmark workflow reruns everything; new tools can join with a single adapter file.

Image and video extraction

Image and video benchmarks cover page-image OCR and embedded video subtitles separately:

Dataset	anymd	Reference alternative
OmniDocBench v1.6 (1,651 page images), overall ↑	21.4 (8.1.0, English tesseract)	TeleOCR 96.91 (author-reported, not our same-run measurement)
MP4 mov_text fixtures (4 clips, 12 cues), text/start recall ↑	91.7% (8.5.1, 11/12)	FFmpeg 100% (12/12)
Matroska SubRip fixtures (4 clips, 12 cues), text/start recall ↑	91.7% (8.5.1, 11/12)	FFmpeg 100% (12/12)

The image score is historical, not a score for the current OCR model. The video scores were measured on 2026-10-08 using small authored regression datasets, not films or lectures; anymd drops a repeated caption at a different timestamp. They measure embedded subtitle extraction, not visual understanding or ASR. The guide links the alternative selection, limitations, timings, raw outputs and reproduction harness.

MCP tools

anymd exposes four tools.

Tool	Use it to	Key arguments
outline	Navigate a heading tree, with node ids and unit/Markdown ranges	source, format (json · tree)
read	Turn a file, URL, or folder into Markdown	source, pages ("1-5,8"), max_tokens (default 20000), cursor, ocr, images (refs · none), revisions (markup · accept · reject), transcript, download_asr_model
search	Find text across files, folders, and URLs	query, sources, mode (auto · literal · ranked), glob, max_results
inspect	Go deeper on a PDF	operation: render_page, extract_regions, ocr_pages, structure (JSON with geometry), compare, inspect, cite_check (quote and location support, anymd Pro)

A read answer looks like this:

---
source: papers/attention.pdf
title: Attention Is All You Need
pages: 15
showing: pages 1-9
---

<!-- page 1 -->

# Attention Is All You Need
…

<!-- page 8 -->

|Model|BLEU EN-DE|BLEU EN-FR|
|-|-|-|
|Transformer (big)|28.4|41.8|
…

<!-- Stopped at the 20000-token budget. Continue with cursor: "10", or pick pages, or raise max_tokens. -->

search answers with one line per hit:

5 matches for "masked language model" (2 files, 31 sections searched)

### papers/bert.pdf (5)
- p.1: …by using a “**masked language model**” (MLM) pre-training objective, inspired by the Cloze task…
- p.2: …In addition to the **masked language model**, we also use a “next sentence prediction” task…

If nothing matches exactly, search falls back to BM25-ranked passages, so a question like "how does bidirectional pretraining work" still finds the right page.

CLI

The same binary is a command-line converter, like MarkItDown but much faster:

anymd report.pdf > report.md                 # a file
anymd deck.pptx notes.docx budget.xlsx        # several files, each with a header
anymd https://example.com/article            # a web page (main content only)
cat scan.png | anymd - --ocr                 # stdin, with OCR
anymd setup ocr                             # one-time: install the OCR engine and pinned local models (~2 GB)
anymd scan.png --ocr vlm                    # tables as Markdown, formulas as LaTeX
anymd paper.pdf --pages 1-3 --max-tokens 4000
anymd search "indemnification" contracts/ --glob '*.pdf'
anymd doctor                                 # lists the optional tools anymd found

Run with no arguments from an MCP client (piped stdin), or as anymd mcp, and it serves MCP over stdio.

Formats

Input	What you get
PDF	Reading-order Markdown: headings, paragraphs, lists, tables, sub/superscripts, <!-- page N --> markers, bookmarks as an outline. Running headers and page numbers are removed. Image-only pages use local doc-VLM OCR after explicit model setup, otherwise installed tesseract. Embedded figures are saved to the anymd cache and marked in place with their caption (images: "refs", the default).
Word .docx	Headings, bold/italic, links, nested lists, tables with merged cells, footnotes, equations as LaTeX, embedded pictures as image files, tracked changes and comments as CriticMarkup
PowerPoint .pptx	One section per slide in deck order, titles, bullets, tables, chart data, speaker notes, pictures as image files
Excel .xlsx .xls .ods · CSV/TSV	One table per sheet, dates as ISO strings, capped at 2,000 rows per sheet
EPUB	One section per chapter in spine order, plus title and author; pictures as image files
HTML and URLs	The main article only: navigation, cookie banners, and sidebars are dropped. Relative links are resolved, and code keeps its language.
Markdown, text, JSON	Returned unchanged, with pagination
Images	Dimensions and EXIF (camera, date, GPS), plus local doc-VLM OCR after model setup, or installed tesseract
Audio / video	Duration, streams, chapters, embedded and sidecar subtitles (via ffprobe/ffmpeg). Local Qwen3-ASR transcript with transcript: true; download_asr_model: true implies a transcript; transcript: true alone never downloads weights.

How it works

For PDFs, anymd reads glyph positions rather than text runs. Glyphs are grouped into lines by baseline, which tolerates super- and subscripts. Word spaces come from the gaps between glyphs, measured against the font size and adjusted for letter tracking. A column-aware XY cut finds gutters between running text. Tables come from drawn lines where a table has them (a missing line between two cells makes a merged cell) and from aligned columns of whitespace where it does not. Wrapped cell text stays in its cell, stacked header lines become one header, and a header over several columns is kept with each of them. Text a reader cannot see (invisible text, or text in the colour of the box behind it) is left out. Pages are processed in parallel and isolated from each other, so one malformed page never fails the whole document. The other formats are parsed natively in Rust (zip/XML, calamine, html5ever); no Python, LibreOffice, or cloud service is involved.

anymd Pro

The anymd core is free and open source (MIT), and nothing that was free has moved to Pro. anymd Pro (current one-time price, from 8.4.0) adds exactly two things for agents that must show their evidence: video timelines with exact, hashed frames (inspect video_timeline and render_frame, and the timeline option of read and outline) and cite-check, which verifies a quote at a page and location in a PDF. Licences are checked offline; no account. Pro funds anymd's development. Buy anymd Pro for instant delivery after payment: copy your licence token from the checkout confirmation page, or recover it through the product's recovery page. Buy from the terminal: anymd pro buy opens the checkout in your browser and turns the payment into a licence token on this machine, so there is nothing to copy. See anymd Pro.

Local and hosted

anymd has two modes, and only one of them runs on your machine:

• Local (free, MIT, this repository). The anymd binary, the MCP server, the CLI and the anymd-core, anymd-pdf and anymd-formats crates. It converts on your machine, uploads nothing, and needs no API key.
• Hosted (Sylphx AI parse, metered). The same crates, pinned at the published version and imported unchanged, serve document parsing for Sylphx AI callers that do not want a local runtime. The call is billed per page and needs a Sylphx AI account. This is the paid mode; there is no licence key and nothing in the local binary is gated by it.

Sylphx AI parse is not a different parser and not a fork: the hosted service imports these crates, so a fix here reaches both modes and the two never drift into separate engines. Only the free local binary lives in this repository; the hosted service lives in the Sylphx platform.

For importers, the anymd-core, anymd-pdf and anymd-formats crate APIs are stable within a major version: no breaking change ships without a major version bump, so the service's pinned version keeps working and is moved forward deliberately, never forced by a patch or minor release.

Security

• Local-first: documents never leave your machine unless you pass a URL, and even then only that URL is fetched.
• URL fetches block private and loopback addresses, and every redirect hop is checked again, pinned to its resolved address.
• --allow-dir=<path> (repeatable) or MCP_PDF_ALLOWED_DIRS confines the server to the directories you list.
• Embedded images are written only to anymd's own cache directory (ANYMD_CACHE_DIR, else the platform cache), never next to the source document, and refused over 50 megapixels.
• External tools (tesseract, ffprobe, ffmpeg) are optional. anymd runs them without a shell, with a timeout and an output cap.

See SECURITY.md to report a vulnerability.
