Available Tools

The LILT MCP server provides the following tools for Claude to use.

Translation

Tool	Description
`translate_text`	Translates a piece of text instantly using LILT.
`translate_files_with_verification`	Creates a formal, verified translation job in LILT.
`get_credit_balance_information`	Checks the current balance for both instant and verified translation credits.
`check_job_status`	Checks the status of a verified translation job.
`download_job`	Triggers a job export and returns a download link for the completed job.

File Handling

Tool	Description	Parameters	Returns
`upload_file`	Uploads a single file to LILT and polls until it is ready for processing. Non-plain-text formats (PDF, DOCX, RTF, PPTX, XLSX, etc.) are expected to already have their text extracted by the client; the tool appends a `.txt` extension to the filename to reflect this (e.g. `report.docx` becomes `report.docx.txt`).	`name` (str), `content` (str, raw or extracted text), `content_type` (str, defaults to `text/plain`)	An object with `id`, `name`, and `status` on success, or `error` and `status` on failure.

Models & Resources

Tool	Description	Parameters	Returns
`create_trained_model`	Creates a new trained translation model for a specific language pair. This is a prerequisite for using `translate_files_with_verification` with that language pair.	`src_lang` (str, IETF BCP 47 tag), `trg_lang` (str, IETF BCP 47 tag)	Nothing (`None`) on success.
`list_resources`	Lists and filters existing jobs or trained models.	`resource_type` (str, `"model"` or `"job"`), `archived` (bool, jobs only, defaults to `False`)	A list of metadata objects. For `"model"`: `src_lang`, `trg_lang`. For `"job"`: `id`, `name`, `src_lang`, `trg_langs`, `num_files`.

Security and Privacy

This server exposes a set of tools that allow Claude or other MCP server hosts to perform actions such as:

Translating text instantly
Uploading files for translation
