MCP tools
The server exposes two tools.
list_converters
Lists all 35+ Convertica converters with their file fields and options. Call this first to find the right tool slug for convert_file. Takes no input.
convert_file
Runs one of convertica.net's 35+ conversion tools on local file(s) and saves the result next to the input (or into output_dir). Requires authentication via the CONVERTICA_API_KEY env var.
Supported conversions include: **PDF ⇄ Word / Excel / PowerPoint / JPG / HTML / Markdown / Text / EPUB**, **PDF → PDF/A**, **HTML / URL → PDF**, **merge / split / compress / rotate / crop / watermark / sign / protect / unlock PDF**, **image convert / optimize / HEIC → JPG·PNG·PDF**, and more. Full list via list_converters or at convertica.net.

Usage notes
- Files are read from and written to your local disk; results are saved next to the input file unless you pass output_dir.
- Conversions run synchronously over HTTPS; processed files are deleted from Convertica's servers right after the response (details).
- API calls are metered against your plan's monthly quota; failed calls are not counted.
