- Agent Document Twin with lossless, visual, semantic, evidence, and agent layers.
- One smart read_pdf tool that auto-profiles and extracts with evidence.
- OCR adapter for scanned pages via configured providers (e.g. Tesseract).
- Visual crops, region analysis, and provider‑normalized evidence.
- Trust reports for hidden text, unsafe links, spoofing, and prompt injection.
- Accessibility reports for tagged‑PDF coverage, headings, links, and forms.
- Deterministic quality benchmarks and release gates for shipped proof.
Setting up with Highlight
This MCP is not yet compatible with Highlight’s one-click setup. However, you can still use it with Highlight by following these steps:
- Download and install Highlight from highlightai.com/download
- Navigate to the plugins tab and select "Add Custom Plugin"
-
Configure the plugin with the settings below
Plugin Name
PDF Reader MCP Server (@sylphlab/pdf-reader-mcp)Command (node, npx, python, etc.)Please refer to the README for specific instructions on how to obtain API keys or other required environment variables.
- Enable "Start Automatically" if you want the plugin to start when Highlight launches
From the repository
Install the npm package @sylphx/pdf-reader-mcp (Node.js ≥22.13 required) via npx, or use the Docker image from GitHub Container Registry. Add it to Claude Desktop config, Claude Code, or any MCP client. The default package works without OCR models, vision models, or cloud credentials. Use the read_pdf tool first with only sources to auto-profile and read the PDF, or use explicit include_* options for precise control. Also supports search_pdf and pdf_evidence tools.
Claude Desktop / Cursor
Paste into your MCP client config file to install this server.

PDFs are not plain text files. They are layout, pixels, tables, hidden text,
permissions, annotations, scanned pages, and ambiguous reading order.
PDF Reader MCP turns that mess into an Agent Document Twin: a linked,
source-backed representation of the PDF that agents can inspect, search,
verify, crop, OCR, enrich, cite, and read with confidence.
If your agent has ever hallucinated from a PDF, lost a table, trusted hidden
text, missed a scanned page, or needed to cite the exact region that proves an
answer, this is the MCP server for that workflow.
Why Agents Use It
| Need | What PDF Reader MCP gives you |
| --- | --- |
| Read the document | Markdown, JSON, HTML, page text, metadata, chunks, and semantic AST. |
| Prove the answer | Page numbers, bounding boxes, evidence IDs, region crops, and source renders. |
| Handle scanned PDFs | Rendered pages routed through configured OCR providers with word boxes and provenance. |
| Recover tables | Selectable-text and OCR-derived tables with cells, geometry, confidence, warnings, and continuation hints. |
| See what text extraction misses | Visual page evidence, focused crops, and configured visual-region provider adapters. |
| Protect the agent | Trust reports for hidden text, prompt-injection-like content, visual spoofing, unsafe links, and redaction. |
| Route accessibility work | Tagged-PDF coverage, tag-visible coverage, headings, images, forms, links, permissions, and page grades. |
| Ship with proof | CI, package smoke, deterministic quality benchmarks, provider artifacts, and release gates. |
Quick Start
Claude Code
claude mcp add pdf-reader -- npx @sylphx/pdf-reader-mcp
Claude Desktop
Add this to claude_desktop_config.json:
{
"mcpServers": {
"pdf-reader": {
"command": "npx",
"args": ["@sylphx/pdf-reader-mcp"]
}
}
}
Any MCP Client
npx @sylphx/pdf-reader-mcp
Node.js >=22.13 is required. The default package works without downloading
OCR models, vision models, Ollama, LM Studio, llama.cpp, or cloud credentials.
