πŸ“„ MCP PDF

A FastMCP server for PDF processing

47 tools for text extraction, OCR, tables, forms, annotations, markdown↔PDF, and more

Python 3.11+ FastMCP License: MIT PyPI

Works great with MCP Office Tools


What It Does

MCP PDF extracts content from PDFs using multiple libraries with automatic fallbacks. If one method fails, it tries another.

Core capabilities:

  • Text extraction via PyMuPDF, pdfplumber, or pypdf (auto-fallback)

  • Table extraction via Camelot, pdfplumber, or Tabula (auto-fallback)

  • OCR for scanned documents via Tesseract

  • Form handling - extract, fill, and create PDF forms

  • Document assembly - merge, split, reorder pages

  • Annotations - sticky notes, highlights, stamps

  • Vector graphics - extract to SVG for schematics and technical drawings

  • Format conversion - PDF ↔ Markdown (PDFβ†’MD via PyMuPDF, MDβ†’PDF via pandoc)


Quick Start

# Run from PyPI (one-shot, no permanent install)
uvx mcp-pdf

# Add to Claude Code β€” note the `--` separator before uvx
claude mcp add pdf-tools -- uvx mcp-pdf

# Include the markdown_to_pdf tool (requires pandoc on host)
claude mcp add pdf-tools -- uvx --from "mcp-pdf[markdown]" mcp-pdf

uvx caches tool installs aggressively. After upgrading to a new release, force a refresh with uvx --refresh mcp-pdf (or uvx --refresh --from "mcp-pdf[markdown]" mcp-pdf if you're using extras).

git clone https://github.com/rsp2k/mcp-pdf
cd mcp-pdf
uv sync

# System dependencies (Ubuntu/Debian)
sudo apt-get install tesseract-ocr tesseract-ocr-eng poppler-utils ghostscript

# For markdown_to_pdf β€” pick one PDF-engine route:
sudo apt-get install pandoc tectonic                                          # recommended (small)
# or:  sudo apt-get install pandoc texlive-xetex texlive-latex-extra          # full TeX
# or:  sudo apt-get install pandoc && pip install weasyprint                  # skip TeX

# Verify
uv run python examples/verify_installation.py

Tools

Content Extraction

Tool

What it does

extract_text

Pull text from PDF pages with automatic chunking for large files

extract_tables

Extract tables to JSON, CSV, or Markdown

extract_images

Extract embedded images

extract_links

Get all hyperlinks with page filtering

ocr_pdf

OCR scanned documents using Tesseract

extract_vector_graphics

Export vector graphics to SVG (schematics, charts, drawings)

Format Conversion

Tool

What it does

pdf_to_markdown

Convert PDF to markdown preserving structure; extracts images and SVG vectors to disk

markdown_to_pdf

Convert .md files (or inline text) to PDF via pandoc with auto-detected engine

markdown_to_pdf requires: pip install mcp-pdf[markdown] plus the pandoc binary and at least one PDF engine (xelatex, pdflatex, tectonic, weasyprint, or wkhtmltopdf) on PATH. The tool auto-detects what's available and uses the highest-quality one. Pass pdf_engine= to override or extra_args= for raw pandoc options.

Document Analysis

What it does

extract_metadata

Get title, author, creation date, page count, etc.

get_document_structure

Extract table of contents and bookmarks

analyze_layout

Detect columns, headers, footers

is_scanned_pdf

Check if PDF needs OCR

compare_pdfs

Diff two PDFs by text, structure, or metadata

analyze_pdf_health

Check for corruption, optimization opportunities

analyze_pdf_security

Report encryption, permissions, signatures

Forms

Permit Forms (Coordinate-Based)

For scanned PDFs or forms without interactive fields. Draws text at (x, y) coordinates.

Tool

What it does

fill_permit_form

validate_permit_form_data

Check data against field schema before filling

preview_field_positions

insert_attachment_pages

Requires: pip install mcp-pdf[forms] (adds reportlab dependency)

Document Assembly

Tool

What it does

merge_pdfs

Combine multiple PDFs with bookmark preservation

split_pdf_by_pages

Split by page ranges

split_pdf_by_bookmarks

Split at chapter/section boundaries

reorder_pdf_pages

Rearrange pages in custom order

Annotations

Tool

What it does

add_sticky_notes

Add comment annotations

add_highlights

Highlight text regions

add_stamps

Add Approved/Draft/Confidential stamps

extract_all_annotations

Export annotations to JSON


How Fallbacks Work

The server tries multiple libraries for each operation:

Text extraction:

  1. PyMuPDF (fastest)

  2. pdfplumber (better for complex layouts)

  3. pypdf (most compatible)

Table extraction:

  1. Camelot (best accuracy, requires Ghostscript)

  2. pdfplumber (no dependencies)

  3. Tabula (requires Java)

If a PDF fails with one library, the next is tried automatically.


Token Management

Large PDFs can overflow MCP response limits. The server handles this:

  • Automatic chunking splits large documents into page groups

  • Table row limits prevent huge tables from blowing up responses

  • Summary mode returns structure without full content

# Get first 10 pages
result = await extract_text("huge.pdf", pages="1-10")

# Limit table rows
tables = await extract_tables("data.pdf", max_rows_per_table=50)

# Structure only
tables = await extract_tables("data.pdf", summary_only=True)

URL Processing

PDFs can be fetched directly from HTTPS URLs:

result = await extract_text("https://example.com/report.pdf")

Files are cached locally for subsequent operations.


System Dependencies

Some features require system packages:

markdown_to_pdf

pandoc + one of: tectonic, texlive-xetex (+ texlive-latex-extra), weasyprint, wkhtmltopdf

Picking a PDF engine for markdown_to_pdf

Pandoc takes markdown β†’ HTML or LaTeX β†’ PDF. The LaTeX path produces the most polished output but needs a TeX install. Trade-offs:

Engine

Disk size

Notes

tectonic

~30 MB

Recommended for new installs. Single static binary. Downloads LaTeX packages on demand β€” no upfront mass-install.

xelatex + texlive-latex-extra

~500 MB

Best output once installed. Use if you already run TeX. The -extra package matters: pandoc's default template needs lastpage, xcolor, framed, fancyhdr, etc. β€” all of which live there, not in texlive-xetex.

xelatex alone (just texlive-xetex)

~200 MB

Often breaks. Expect ! LaTeX Error: File 'X.sty' not found on real docs.

weasyprint

~40 MB

Pure-Python (pip install weasyprint) + cairo/pango system libs. HTML/CSS path β€” no LaTeX. Good for simple docs; weaker on math, footnotes, citations.

wkhtmltopdf

~40 MB

Older HTML-to-PDF tool. Adequate but less actively maintained.

Ubuntu/Debian:

sudo apt-get install tesseract-ocr tesseract-ocr-eng poppler-utils ghostscript default-jre-headless

# For markdown_to_pdf β€” pick one engine route:

# Option A β€” tectonic (smallest, downloads packages on demand)
sudo apt-get install pandoc
# tectonic isn't in apt β€” install via cargo or download static binary:
#   https://tectonic-typesetting.github.io/en-US/install.html

# Option B β€” full TeX (best quality, large download)
sudo apt-get install pandoc texlive-xetex texlive-latex-extra texlive-fonts-extra

# Option C β€” weasyprint (skip TeX entirely)
sudo apt-get install pandoc
pip install weasyprint

Arch Linux:

sudo pacman -S tesseract tesseract-data-eng poppler ghostscript jre-openjdk-headless

# For markdown_to_pdf β€” pick one engine route:

# Option A β€” tectonic (recommended for new installs, in official repo)
sudo pacman -S pandoc tectonic

# Option B β€” full TeX (best output, ~500 MB)
sudo pacman -S pandoc texlive-xetex texlive-latexextra texlive-fontsextra

# Option C β€” weasyprint (skip TeX)
sudo pacman -S pandoc
pip install weasyprint   # or: uv pip install weasyprint

# Option D β€” wkhtmltopdf (from AUR)
yay -S wkhtmltopdf-static

macOS (Homebrew):

brew install tesseract poppler ghostscript

# For markdown_to_pdf β€” pick one engine route:

# Option A β€” tectonic (recommended)
brew install pandoc tectonic

# Option B β€” full TeX (mactex-no-gui includes the latex-extra equivalent)
brew install pandoc
brew install --cask mactex-no-gui

# Option C β€” weasyprint
brew install pandoc weasyprint
