Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| read_pdf_structureA | Extract the complete structural content of a PDF document. Returns detailed information about each page including:
Use this tool FIRST to understand the document layout before making any modifications. The output helps identify exact text to target for replacements. |
| inspect_pdf_fontsA | Search for specific text terms and report their font properties. Use this tool to understand the exact font styling of text you want to replace. This ensures replacements will match the surrounding document style as closely as possible. The tool searches through all pages and returns matches with:
|
| modify_pdf_contentA | Find and replace text in a PDF while preserving font styles. This tool performs text replacement by:

| list_pdf_hyperlinksA | Extract all existing hyperlinks and clickable URIs from a PDF. Use this tool to inventory the links in a document before or after making modifications. It reports the target URI, its location (bbox), and the text covered by the link if detectable. |
| extract_embedded_fontsA | Extract metadata and buffers of all embedded fonts in a PDF. Use this tool to inspect which fonts are actually embedded in a document. Custom fonts (TrueType, OpenType) appear as Type0 with their binary buffer. Base 14 system fonts (Helvetica, Times, Courier) are NOT embedded and will not appear in the results. |
| batch_modify_pdf_contentA | Apply the same text replacements to multiple PDF files at once. Each file is processed independently -- a failure in one file does
not stop the rest of the batch. Output files are written to

Scored across 6 tools
Most tools have clearly distinct purposes: reading structure, modifying content, listing hyperlinks, and batch processing are unambiguous. However, read_pdf_structure and inspect_pdf_fonts both report font name, size, and coordinates, so an agent could be uncertain which to use when investigating text styling.
All tools follow a consistent verb_noun snake_case pattern (extract_, read_, inspect_, modify_, list_, batch_modify_). The batch_ prefix clearly signals the multi-file variant of modify_pdf_content, making the naming predictable and scannable.
Six tools is a well-scoped set for a PDF modification server. Each tool covers a distinct aspect of the domain—inspection, single-file modification, batch modification, font analysis, and hyperlink inventory—without bloat or redundancy.
The core workflow is covered: read structure, inspect fonts, modify text, list hyperlinks, and batch process. Minor gaps exist such as no page-level operations (reorder, delete, rotate) or image extraction, but these fall outside the server's evident text-and-link modification focus.
