30-Second Quickstart

1. Get a free API key → ****

2. Install & configure:

# Install the skill (works with 40+ agents)
npx skills add PSPDFKit-labs/nutrient-agent-skill

# Set your API key
export NUTRIENT_API_KEY="pdf_live_..."

3. Ask your agent:

"Extract the text from invoice.pdf"

That's it. Your agent now has full document processing capabilities — no MCP setup required.

Supported Agents

Works out of the box with 40+ AI coding agents:

Any agent that supports the Agent Skills standard works automatically.

Real-World Workflows

🔍 Workflow 1: OCR a scanned document and extract text

You have a scanned PDF — no selectable text. Ask your agent:

"OCR scanned-contract.pdf in English and extract the text to a file"

What happens:

scanned-contract.pdf (image-only)
  → OCR (English) → searchable-contract.pdf (selectable text)
  → Extract text → contract-text.txt

📋 Workflow 2: Fill a PDF form and sign it

You have an onboarding form to complete. Ask your agent:

"Fill employee-onboarding.pdf with name 'Jane Smith', start date '2026-03-01', and department 'Engineering', then digitally sign it"

What happens:

employee-onboarding.pdf (blank form)
  → Fill fields (name, date, department)
  → Digital signature (CMS)
  → employee-onboarding-signed.pdf ✅

🔒 Workflow 3: Redact PII before sharing

You need to share a document but it contains sensitive data. Ask your agent:

"Redact all social security numbers, email addresses, and credit card numbers from patient-records.pdf"

What happens:

patient-records.pdf (contains PII)
  → Detect SSNs, emails, credit cards
  → Apply black redaction boxes (irreversible)
  → patient-records-redacted.pdf 🔒

Tip: For smarter redaction, try: "Use AI redaction to find and remove all personally identifiable information from contract.pdf" — this uses contextual AI analysis instead of pattern matching.

Alternative Integrations

MCP Server (For agents with MCP support)

The Nutrient DWS MCP Server provides all operations as native agent tools with file I/O handling and sandboxing.

npx @nutrient-sdk/dws-mcp-server

Add to your MCP config (e.g., claude_desktop_config.json):

{
  "mcpServers": {
    "nutrient-dws": {
      "command": "npx",
      "args": ["-y", "@nutrient-sdk/dws-mcp-server"],
      "env": {
        "NUTRIENT_DWS_API_KEY": "YOUR_API_KEY",
        "SANDBOX_PATH": "/path/to/working/directory"
      }
    }
  }
}

📦 npm · GitHub
