UFC-MCP — Universal File Converter MCP

A full-featured Model Context Protocol server that lets Claude Desktop (or any MCP host) convert audio, video, image, document, and specialized scientific/business files — all running locally with no cloud dependencies.

Features

📄 Document	Markdown, JSON, YAML, HTML, CSV, TXT	Node.js
📊 Spreadsheet	CSV, TSV, XLSX, JSON, HTML, Markdown	Node.js
🗜️ Archive	ZIP, GZIP, BZIP2, TAR, 7Z, RAR	Node.js + CLI
🔤 Font	TTF, OTF, WOFF, WOFF2	fonttools
🎨 3D Models	OBJ, STL, PLY, GLTF, GLB	Node.js + assimp
📧 Email	EML, MBOX → JSON/HTML/TXT	Node.js
🎼 Music Notation	MIDI, ABC, MusicXML → JSON	Node.js
🧬 Biotech	FASTA, FASTQ, VCF, GFF, PDB* → JSON/CSV	Node.js
💰 Fintech	OFX, QFX, QIF, MT940 → JSON/CSV	Node.js
📦 Logistics	EDI, EDIFACT, GPX → JSON/GeoJSON	Node.js
⚙️ Dev Formats	TOML, INI, ENV, XML, Protobuf → JSON	Node.js
📈 Statistics	R, MATLAB, SPSS, Stata → JSON/CSV	Node.js + Python*
🧪 Chemistry	MOL, SDF, XYZ, SMILES → JSON/CSV; PDB* (via external RDKit/Open Babel tools)	Node.js + RDKit*
🔭 Astronomy	FITS → JSON/CSV (header)	Node.js + astropy*
🌍 Geoscience	KML, GeoJSON, NetCDF*, HDF5* → JSON	Node.js + Python*

* Some advanced features require optional Python libraries. PDB* conversion currently relies on external RDKit/Open Babel tooling and is not handled by the built-in ChemistryProcessor.
