## MCP tools (9)

### `pdf_info` (~79 tokens)

PDF info

Read a PDF on this machine and report its page count, page sizes, title and whether it was encrypted. Use before splitting, extracting or rotating to learn how many pages there are.

Input parameters:

- `password` (string): Password for a PDF that asks for one when opened. Used only on this machine.
- `path` (string, required): Path to the PDF.

### `merge_pdfs` (~120 tokens)

Merge PDFs

Combine several PDFs on this machine into one, in the order given. The same file may appear more than once. Writes a new PDF and returns its path.

Input parameters:

- `inputs` (array, required): PDF paths, in the order their pages should appear.
- `output` (string): Where to write the result. Defaults to a new file beside the input. Existing files are never overwritten; a free name like file-1.pdf is used instead.

### `extract_pdf_pages` (~179 tokens)

Extract, reorder or delete PDF pages

Write a new PDF containing only the listed pages, in the listed order. Use it to pull out a range, reorder pages ("3,1,2") or drop pages (list the ones to keep). Pages are 1-based; ranges like "1-3, 7" and reversed ranges like "5-1" work.

Input parameters:

- `input` (string, required): Path to the PDF.
- `output` (string): Where to write the result. Defaults to a new file beside the input. Existing files are never overwritten; a free name like file-1.pdf is used instead.

### `split_pdf` (~115 tokens)

Split PDF

Split a PDF into several files of N pages each (1 = one file per page), written into a folder. Returns the list of files.

Input parameters:

- `input` (string, required): Path to the PDF.
- `output_dir` (string): Folder for the parts. Defaults to a new folder beside the input named <file>-split.
- `pages_per_file` (integer): Pages in each output file. Default 1.

Input parameters:

- `degrees` (required): Clockwise rotation to add.
- `input` (string, required): Path to the PDF.
- `output` (string): Where to write the result. Defaults to a new file beside the input. Existing files are never overwritten; a free name like file-1.pdf is used instead.
- `pages` (string): Pages to rotate, for example "1, 3-4". Default: every page.
- `password` (string): Password for a PDF that asks for one when opened. Used only on this machine.

### `number_pdf_pages` (~196 tokens)

- `margin` (number): Margin in points (72 = 1 inch).
- `output` (string): Where to write the result. Defaults to a new file beside the input. Existing files are never overwritten; a free name like file-1.pdf is used instead.
- `page_size` (string): "fit" makes each page the size of its image; "a4" and "letter" centre the image on a standard page.

### `inspect_image_metadata` (~74 tokens)

Inspect photo metadata

Report the metadata hidden in a JPG, PNG or WebP photo: GPS location, camera make and model, capture time, editing software, and which blocks (EXIF, XMP, IPTC, comments) are present. HEIC files report EXIF only.

Input parameters:

- `path` (string, required): Path to the image.

### `strip_image_metadata` (~122 tokens)

Remove photo metadata

Write a copy of a JPG, PNG or WebP photo with EXIF (including GPS location), XMP, IPTC and comments removed. Lossless: the image data is not re-encoded. The original file is left untouched.

Input parameters:

- `input` (string, required): Path to the image.
- `keep_color_profile` (boolean): Keep the ICC colour profile so colours look the same. Default true.
- `output` (string): Where to write the cleaned copy. Defaults to <name>-clean.<ext> beside the input. Existing files are never overwritten.

StayPut exposes 9 tools: pdf_info, merge_pdfs, extract_pdf_pages, split_pdf, rotate_pdf, and 4 more. Their descriptions and schemas cost roughly 1,178 tokens of context every time the server is loaded.

### Is the StayPut MCP server still maintained?

StayPut is still listed as active in the MCP registry. We last reached this channel on 23 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
