Nutrient Document Processing (Universal Agent Skill)
Best for Claude Code/Codex/Gemini/Cursor/Windsurf and other non-OpenClaw agents. Process, convert, extract, OCR, redact, sign, and manipulate documents using the Nutrient DWS Processor API.
Setup
You need a Nutrient DWS API key. Get one free at https://dashboard.nutrient.io/sign_up/?product=processor.
Option 1: MCP Server (Recommended)
If your agent supports MCP (Model Context Protocol), use the Nutrient DWS MCP Server. It provides all operations as native tools. Configure your MCP client (e.g., claude_desktop_config.json or .mcp.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" } } } } Then use the MCP tools directly (e.g., convert_to_pdf, extract_text, redact, etc.).
Option 2: Direct API (curl)
For agents without MCP support, call the API directly: export NUTRIENT_API_KEY="your_api_key_here" All requests go to https://api.nutrient.io/build as multipart POST with an instructions JSON field.
Safety Boundaries
This skill sends documents to the Nutrient DWS API (api.nutrient.io) for processing. Documents may contain sensitive data โ ensure your Nutrient account's data handling policies are acceptable. It does NOT access local files beyond those explicitly passed for processing. It does NOT store API keys or credentials beyond the current session. MCP server mode (npx @nutrient-sdk/dws-mcp-server) downloads the official Nutrient MCP server package from npm at runtime. All API calls require an explicit API key โ no anonymous access is possible.

curl -X GET https://api.nutrient.io/credits \ -H "Authorization: Bearer $NUTRIENT_API_KEY"
Best Practices
Use the MCP server when your agent supports it โ it handles file I/O, error handling, and sandboxing automatically. Set SANDBOX_PATH to restrict file access to a specific directory. Check credit balance before batch operations to avoid interruptions. Use AI redaction for complex PII detection; use preset/regex redaction for known patterns (faster, cheaper). Chain operations โ the API supports multiple actions in a single call (e.g., OCR then redact).
