pdfnative MCP

A local-first MCP server exposing 28 production-grade tools for PDF generation, archival (PDF/A), print exchange (PDF/X-4), PAdES signing with long-term validation, AcroForms, merge/split, encryption, and layout preview. It uses a zero-dependency, ISO 32000-1 compliant engine to empower AI agents like Claude, Cursor, and Zed to securely create, sign, verify, and transform documents.
