Converter MCP server

• check_conversionFree

  Check whether one format can be converted to another before sending a file. Returns the engine, whether AI Deep Read is needed, the options it accepts, and alternatives when the pair is not supported. Formats accept ids (docx), extensions (jpeg) or common names (word, excel).

• convert_fileFree

  Convert a file. Provide the content as base64 OR a public https URL. `from` is optional when the filename/URL has an extension. Text outputs (Markdown, CSV, JSON, HTML…) up to 200 KB are returned inline as `text`; other outputs are returned as `base64` plus a `downloadUrl` that accepts the same bearer token. Max 10 MB per file. Set `deepRead: true` to read scans, photos and handwriting with AI Deep Read (1 credit per page).

• get_conversionFree

  Fetch a previous conversion by id: status, warnings, and the output (inline text or base64) if it is still retained.

• list_conversionsFree

  List supported target formats for a source format (or every source that can produce a target). Returns compact {from,to,slug,engine,mode} rows.

• list_formatsFree

  List every file format this converter reads or writes (id, name, extensions, family). Use the id values as `from`/`to` in other tools.
