📄 MCP PDF

A FastMCP server for PDF processing

41 tools for text extraction, OCR, tables, forms, annotations, and more

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

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:

Feature	Dependency
OCR	tesseract-ocr
Camelot tables	ghostscript
Tabula tables	default-jre-headless
PDF to images	poppler-utils

Ubuntu/Debian:

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

---

Configuration

Optional environment variables:

Variable	Purpose
MCP_PDF_ALLOWED_PATHS	Colon-separated directories for file output
PDF_TEMP_DIR	Temp directory for processing (default: /tmp/mcp-pdf-processing)
TESSDATA_PREFIX	Tesseract language data location
