Translate text and documents, manage glossaries, and check quota via the DeepL API.
DeepL ships in the w6w first-party pack. It declares 8 actions, 2 health checks, and the host runs its code in a sandbox that never sees the credential.
io.w6w.deeplDeepL translates text and documents and manages the glossaries that keep specific terms consistent across translations. Run a translation with a source and target language, or hand off a document for background translation — upload, poll status, then download the finished file, since large documents can take minutes and don’t fit a single blocking call.
The app follows DeepL’s own account-tier split without needing separate configuration: Free and Pro keys route to different hosts automatically based on the key itself, so the same connection setup works either way. Reading usage — characters translated against the plan limit, and document count where a cap applies — gives a workflow a way to check quota before spending it on a large job.
A good fit for translating support tickets, product content or documents as part of a larger workflow, especially where consistent terminology matters enough to maintain a glossary rather than translating cold each time.
Three routes to the same 8 actions. The Workflow tab is generated from DeepL's own manifest and carries its real ids, so it is copy-pasteable; the Code and CLI examples are the same call for any action on any app, so every app-specific value in them is a blank you fill in.
document-download Download the translated file for a completed document job.
document-status Check the translation status of a document submitted via Translate Document.
get-usage Character (and document, where applicable) usage for the current billing period.
list-languages List every language DeepL supports for text translation (source and target).
translate-document Upload a document to DeepL for translation. Returns a job to poll and download.
A workflow step names the app and the action, and the editor fills in the
connection when you pick one. This is the Step shape from the
workflow spec, carrying DeepL's real ids.

Every app-specific value here is a blank you have to fill in. An
app action is reached through the connection that authenticates it, so the
address is a connection id, not the app id — and connections belong to your account,
so a public page cannot know yours. Create one for DeepL, then fill in
the three blanks: conn_YOUR_CONNECTION_ID, the action key, and the
parameters that action declares. The call itself is real — the shape is transcribed
from the studio's own snippet builder, which prints the same kind of blanks — but
nothing in it is specific to DeepL. The Workflow tab is where this app's
real ids are.

One MCP endpoint exposes every app, function and workflow the caller is entitled to, as tools it can discover and run. Access is granted per team while we onboard.
One tool call{
"name": "w6w_invoke",
"arguments": {
"ref": "app:io.w6w.deepl#document-download",
"input": {
"documentId": "<documentId>",
"documentKey": "<documentKey>"
}
}
}
Every tool names its target with a single ref. The
app: form above doesn't name a connection at all — the
host resolves which of the caller's DeepL connections to sign
with, and refuses rather than guesses when the answer is ambiguous.
The token is attached host-side, at the moment of the call. It is never a tool argument, never in the model's context, and never in a transcript — so a prompt injection has nothing to exfiltrate.
Tools are derived per end user from what that person has actually connected and is entitled to — not one shared bot identity carrying the union of everyone's access.
Multi-step work runs on the workflow engine and returns a run handle the agent can poll — retries, branching and state survive the conversation that started them.
DeepL's declared health checks are on the surface too, so an agent can tell "the vendor is down" from "your credential expired" before it burns a retry on either.
The MCP surface is part of the hosted platform. DeepL itself is MIT, and the runtime that executes it is source-available (FSL).
DeepL declares its own checks, so its health is a property of the app rather than something the host guesses at.
Overall platform + per-datacenter status from DeepL's own status page backend, and any incident not marked resolved.
