MCP server bundled into CoolUtils Mail Viewer — a 15-year-old Windows tool for opening exotic email formats. Run MailViewer.exe --mcp and Claude can convert .eml/.msg/.p7m/.mim/.tnef/.olk15/.vcf (+5 more) to PDF/DOCX/HTML/TXT/TIFF with full rendering, pull sender/subject/headers/attachments as JSON, and bulk-extract attachments from folders. Fully local — mail never leaves your machine. Built for DFIR, eDiscovery, paralegal, and IT-admin workflows on Outlook archives and S/MIME-signed mail.
