Client Setup

<details> <summary><strong>Claude Desktop</strong></summary>

Add to your Claude Desktop config (claude_desktop_config.json):

{
  "mcpServers": {
    "pdf-toolkit": {
      "command": "npx",
      "args": ["-y", "@aryanbv/pdf-toolkit-mcp"]
    }
  }
}

</details>

<details> <summary><strong>Claude Code</strong></summary>

claude mcp add pdf-toolkit -- npx -y @aryanbv/pdf-toolkit-mcp

</details>

<details> <summary><strong>Cursor</strong></summary>

Add to .cursor/mcp.json (project) or ~/.cursor/mcp.json (global):

{
  "mcpServers": {
    "pdf-toolkit": {
      "command": "npx",
      "args": ["-y", "@aryanbv/pdf-toolkit-mcp"]
    }
  }
}

</details>

<details> <summary><strong>VS Code</strong></summary>

VS Code uses "servers", NOT "mcpServers". Copying the config from other clients will silently fail. Requires the GitHub Copilot extension with Agent mode enabled.

Add to .vscode/mcp.json:

{
  "servers": {
    "pdf-toolkit": {
      "command": "npx",
      "args": ["-y", "@aryanbv/pdf-toolkit-mcp"]
    }
  }
}

</details>

<details> <summary><strong>Windsurf</strong></summary>

Add to ~/.codeium/windsurf/mcp_config.json:

{
  "mcpServers": {
    "pdf-toolkit": {
      "command": "npx",
      "args": ["-y", "@aryanbv/pdf-toolkit-mcp"]
    }
  }
}

Templates

Generate professional documents from structured data:

"Create an invoice for Acme Corp"

{
  "templateName": "invoice",
  "data": {
    "companyName": "Your Company",
    "clientName": "Acme Corp",
    "invoiceNumber": "INV-001",
    "invoiceDate": "2026-04-01",
    "items": [
      { "description": "Web Development", "quantity": 40, "unitPrice": 150 },
      { "description": "Hosting (Annual)", "quantity": 1, "unitPrice": 299 }
    ],
    "taxRate": 18,
    "paymentTerms": "Net 30"
  },
  "outputPath": "/path/to/invoice.pdf"
}

Available templates: invoice, report, letter.

Encryption

"Encrypt report.pdf with password 'secure123'"

Applies RC4 128-bit encryption. Set separate user (open) and owner (edit) passwords for granular access control.

QR Codes & Barcodes

"Add a QR code linking to our website on page 1"

Supported types: QR Code, Code128, DataMatrix, EAN-13, PDF417, Aztec Code. Position and size are fully configurable.

Usage Examples

Just ask naturally:

• "Create a PDF from this Markdown report"
• "Generate an invoice for Client Corp — 10 hours consulting at $150/hr"
• "Merge january.pdf and february.pdf into q1-combined.pdf"
• "Extract text from pages 5-10 of thesis.pdf"
• "Fill the Name field with 'John Doe' in application.pdf"
• "Add a CONFIDENTIAL watermark to draft.pdf"
• "Encrypt financials.pdf with password 'budget2026'"
• "Add page numbers to presentation.pdf"
• "Embed a QR code with our URL on the cover page"
• "Reorder pages as 3,1,2 in report.pdf"

Known Limitations

• Merge/Split/Reorder: Form fields are not preserved. Visual content transfers, but interactive fields are lost.
• Text extraction: Returns PDF stream order, not visual reading order. Multi-column layouts may interleave.
• Extract text: Defaults to first 10 pages to avoid exceeding LLM context. Request specific pages for longer documents.
• Image embedding: Only JPEG and PNG formats are supported.
• Form filling: Non-Latin characters (Arabic, CJK, Devanagari) require providing a custom font file (.ttf/.otf).
• Encryption: Uses RC4 128-bit, not AES. Adequate for access control but not modern strong encryption.
• Markdown fonts: pdfmake uses Roboto only. Custom fonts are not yet supported for Markdown PDFs.

Tech Stack

Dual-engine architecture for maximum capability:

• pdfmake — Rich document creation (Markdown, templates, tables, headers/footers)
• @pdfme/pdf-lib — Existing PDF manipulation (merge, split, rotate, watermark, forms, images, QR codes)
• unpdf — Text extraction and metadata reading

Requirements

• Node.js >= 18

Development

npm install          # Install dependencies
npm run build        # Compile TypeScript
npm run test         # Run all 51 tests
npm run inspect      # Open MCP Inspector (requires Node >= 22.7.5)
