## MCP tools (3)

### `pdf_to_markdown` (~208 tokens)

PDF → Markdown

Decompile a PDF into Markdown (headings, lists, tables, math as LaTeX) locally. Born-digital pages take milliseconds; scans and screenshots get on-device OCR only where needed. Nothing is uploaded. Use pdf_outline first on long documents to pick pages.

Input parameters:

- `base64` (string): Raw PDF bytes, base64-encoded
- `lang` (string): Tesseract language(s) for OCR, e.g. 'eng', 'deu', 'eng+ara' (default 'eng')
- `maxChars` (integer): Truncate the Markdown to this many characters (default 200000)
- `ocr` (boolean): Escalate ink the text layer cannot explain to on-device OCR (default true)
- `pages` (string): Page selection like '1-3,7' (default all)
- `path` (string): Path to a PDF on this machine
- `url` (string): URL of a PDF to fetch

### `pdf_outline` (~137 tokens)

PDF outline

List the headings of a PDF with their level and page number, so you can decide which pages to read with pdf_to_markdown.

Input parameters:

- `base64` (string): Raw PDF bytes, base64-encoded
- `lang` (string): Tesseract language(s) for OCR, e.g. 'eng', 'deu', 'eng+ara' (default 'eng')
- `ocr` (boolean): Escalate ink the text layer cannot explain to on-device OCR (default true)
- `path` (string): Path to a PDF on this machine
- `url` (string): URL of a PDF to fetch

### `pdf_tables` (~136 tokens)

PDF tables

Extract every table in a PDF as JSON rows: [{ page, rows: string[][] }]. The first row is the header.

Input parameters:

- `base64` (string): Raw PDF bytes, base64-encoded
- `lang` (string): Tesseract language(s) for OCR, e.g. 'eng', 'deu', 'eng+ara' (default 'eng')
- `ocr` (boolean): Escalate ink the text layer cannot explain to on-device OCR (default true)
- `path` (string): Path to a PDF on this machine
- `url` (string): URL of a PDF to fetch

### Is the pdffr MCP server safe to use?

pdffr scores 78 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 25 September 2026. It declares no install or post-install scripts. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the pdffr MCP server expose?

pdffr exposes 3 tools: pdf_to_markdown, pdf_outline, pdf_tables. Their descriptions and schemas cost roughly 481 tokens of context every time the server is loaded.

### Is the pdffr MCP server still maintained?

### What licence is the pdffr MCP server under?

pdffr declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
