# Nutrient DWS MCP Server (MCP server) > Nutrient DWS MCP Server is an MCP server that adds productivity tools to AI assistants such as Claude Desktop, Claude Code and Cursor. Nutrient Processor + Data Extraction MCP: convert, OCR, sign, redact, and extract PDFs/Office docs. It has 71 GitHub stars, is released under the MIT license and runs locally with npx -y @nutrient-sdk/dws-mcp-server. Give AI agents the power to generate, read, extract, process, and sign documents. A Model Context Protocol (MCP) server that connects AI assistants to the Nutrient Document Web Service (DWS) Processor and Data Extraction APIs — enabling document creation, editing, conversion, digital signing, OCR, and redaction, plus structured data extraction (typed JSON with bounding boxes and confidence, or schema-guided field extraction with per-field citations) through natural language. ## Key facts | Fact | Value | |---|---| | Repository | https://github.com/PSPDFKit/nutrient-dws-mcp-server | | GitHub stars | 71 | | License | MIT | | Language | TypeScript | | Transport | stdio | | Packages | npm: @nutrient-sdk/dws-mcp-server | | Remote URL | none | | Needs API key | yes | | Official | yes | | Works with | Claude Desktop, Claude Code, Cursor, VS Code | | Category | Productivity | | Latest release | v0.1.3 (Aug 28, 2026) | | Last commit | Aug 28, 2026 | | MCP registry name | io.github.PSPDFKit/nutrient-dws-mcp-server | ## Install ### Claude Desktop (claude_desktop_config.json) ```json { "mcpServers": { "nutrient-dws-mcp-server": { "command": "npx", "args": [ "-y", "@nutrient-sdk/dws-mcp-server" ], "env": { "NUTRIENT_DWS_API_KEY": "your-value", "NUTRIENT_DWS_EXTRACTION_API_KEY": "your-value" } } } } ``` Settings > Developer > Edit Config. macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\.

Optional for local desktop use (browser sign-in on first request); required for CI or headless environments. - `NUTRIENT_DWS_EXTRACTION_API_KEY` (secret): Data Extraction API key (starts with pdflive), needed for parsedocument and extractfields in static-key mode. OAuth covers both products. - `SANDBOX_PATH`: Local directory the server is allowed to read and write documents in. - `LOG_LEVEL`: Minimum logging level; defaults to info. - `MCP_LOG_FILE`: Log file path; defaults to a temporary file in stdio mode. ## Tools - `document_processor`: Document processing for conversions, OCR, watermarking, rotation, annotation flattening, and redaction workflows - `parse_document`: Structured data extraction (DWS Data Extraction API): typed JSON elements with bounding boxes and confidence, or… - `extract_fields`: Schema-guided field extraction (DWS Data Extraction API): pulls specific named fields into a JSON shape you define,… - `document_signer`: PDF signing with CMS / PKCS#7 and CAdES signatures plus visible or invisible appearance options - `ai_redactor`: AI redaction for detecting and permanently removing sensitive content such as names, addresses, SSNs, emails, and… - `check_credits`: Read-only account lookup for current DWS credits and usage. No document content is uploaded - `sandbox_file_tree`: Read-only view of files inside the configured sandbox directory - `directory_tree`: Read-only view of local files when sandbox mode is disabled.
