pdf-agent-toolkit-mcp

PDF Agent Toolkit & MCP Server (inspired by ihatepdf.cv)

A comprehensive, privacy-first PDF manipulation suite and Model Context Protocol (MCP) server for AI Agents (Claude Desktop, Cursor, Windsurf, LangChain, Claude Code).

Core Philosophy

  1. Zero Cloud Uploads: All PDF processing (compression, page reordering, rotation, redaction, and text extraction) executes 100% locally in pure TypeScript & WebAssembly.

  2. Agent Token Optimization: Eliminates context bloat by avoiding raw PDF base64 dumps in prompts; returns structured outlines and page snippets on demand.

  3. Universal Compatibility: Works out of the box with stdio JSON-RPC 2.0.

Tool Name

Category

Description

Agent Optimization

compress_pdf

Optimization

Reduces file size via stream defragmentation and DPI presets (screen, ebook, printer).

Reduces downstream OCR/vision token weight by up to 70%.

extract_pdf_content

Intelligence

Extracts document TOC, outline, word count, and clean Markdown text.

Saves ~90% context tokens compared to raw stream dumping.

scan_and_redact_pii

Security

Detects SSNs, Emails, Credit Cards, Aadhaar numbers, and custom keywords, stamping black redaction boxes.

Ensures GDPR/HIPAA compliance prior to sending docs to external LLMs.

organize_pdf

Structure

Compound tool: reorders, deletes, rotates (90/180/270°), and adds page numbers in one atomic pass.

Prevents multi-turn roundtrips.

split_pdf

Structure

Extracts specific page ranges (e.g. "1-3, 5, 8-12").

Allows agents to inspect specific chapters.

merge_pdfs

Structure

Combines multiple input PDFs into a single document.

Fast multi-file document compilation.

stamp_watermark

Security

Stamps visual text watermarks (e.g. "DRAFT", "CONFIDENTIAL") with custom rotation and opacity.

Visual status stamping.

create_pdf_from_text

Creation

Formats clean Markdown/text into an A4 PDF with stylized header banners.

Lightweight document generation without headless browser bloat.

inspect_and_fill_form

Forms

Inspects AcroForm fields and fills form data.

Automates invoice, tax, and contract processing.


🚀 Quickstart Configs for Agents

1. Cursor IDE (.cursor/mcp.json)

{
  "mcpServers": {
    "pdf-agent-toolkit": {
      "command": "npx",
      "args": ["-y", "pdf-agent-toolkit-mcp@latest"]
    }
  }
}

2. Claude Desktop (claude_desktop_config.json)

{
  "mcpServers": {
    "pdf-tools": {
      "command": "npx",
      "args": ["-y", "pdf-agent-toolkit-mcp"]
    }
  }
}

3. LangChain & LangGraph (Python)

from langchain_mcp_adapters.client import MultiServerMCPClient
from langgraph.prebuilt import create_react_agent
from langchain_google_genai import ChatGoogleGenerativeAI

async def main():
    async with MultiServerMCPClient({
        "pdf_tools": {
            "command": "npx",
            "args": ["-y", "pdf-agent-toolkit-mcp"],
            "transport": "stdio",
        }
    }) as client:
        tools = client.get_tools()
        model = ChatGoogleGenerativeAI(model="gemini-2.5-flash")
        agent = create_react_agent(model, tools)
        
        response = await agent.ainvoke({
            "messages": [("user", "Compress ./financials.pdf and blackout sensitive SSNs")]
        })
        print(response)
