About
Secure MCP server for analyzing Excel files with oletools
Explore
Analyzes VBA Macros (olevba)
Detects XLM Macros (XLMMacroDeobfuscator, olevba)
Checks for DDE Links (msodde)
Extracts embedded OLE Objects (oleobj)
Analyzes XLL file exports for suspicious functions (pefile)
Extracts IOCs (URLs, IPs, Hashes, Emails) using iocextract

This project provides a secure microservice using FastMCP to analyze Microsoft Office documents (Excel, Word, PowerPoint) and related file types (like XLL add-ins) for potential malicious content using static analysis techniques. It leverages external tools like oletools, XLMMacroDeobfuscator, and pefile.
