## About PDF Blocks with LuumenAI

Connect PDF Blocks and your document handoffs become steps the agent can run for you. Merge change records in order, extract or remove pages, add a text or image watermark, and add or remove a password. Every operation is a write, so it comes previewed and approved by default, then logged. Luumen authenticates with an API key.

## Example tools

Write and destructive (17 in total, approval required by default):

- `PDF_BLOCKS_ADD_IMAGE_WATERMARK` — Add a PNG or JPEG image as a watermark on all or selected PDF pages.
- `PDF_BLOCKS_ADD_PASSWORD` — Create an encrypted copy of a PDF that requires a password to open.
- `PDF_BLOCKS_ADD_RESTRICTIONS` — Create an encrypted PDF copy with explicit permissions for copying, editing, printing, forms, assembly, and accessibility.
- `PDF_BLOCKS_ADD_TEXT_WATERMARK` — Add up to three styled text lines as a watermark on all or selected PDF pages.
- `PDF_BLOCKS_EXTRACT_PAGES` — Create a PDF containing selected source pages in their original order.
- `PDF_BLOCKS_MERGE_PDFS` — Merge PDF files into one PDF in the exact order provided.
- `PDF_BLOCKS_REMOVE_PAGES` — Create a PDF with selected pages removed while preserving the remaining page order.
- `PDF_BLOCKS_REMOVE_PASSWORD` — Create an unencrypted copy of a password-protected PDF using its current password.
