Connect Claude & ChatGPT to DeepL

Ask your AI to translate text through your own DeepL account, using your glossaries and style rules. It can fix spelling and grammar or rephrase text with DeepL Write, create and update glossaries and search your translation memories. It can also tell you how many characters you have used this billing period.

Questions

What can the AI do in DeepL?

The AI can translate text, correct and rephrase text with DeepL Write, and list supported languages. It can list, read, create, rename, update and delete glossaries, read style rules, search translation memories and check your character usage.

Does the AI see my DeepL API key?

No. Your DeepL API key is encrypted at rest and never shown to the AI. After you save it, it is not shown again, not even to you. The AI only sees the results of the tools it calls.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on, so you can allow translation without glossary changes. Deleting a glossary is permanent and replacing entries overwrites the old ones, so those tools can require your approval before they run. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT go to Settings › Apps & Connectors › Advanced and turn on Developer mode, then add your PipMCP link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.

What does it cost?

PipMCP has a free plan with no credit card required. Paid plans bill per completed task. You also need your own DeepL API key, and your character usage counts against your DeepL account.

Does it work with a DeepL API Free key?

Yes. When you connect, you choose the API host that matches your key. Free keys end in :fx and use api-free.deepl.com, and Pro keys use api.deepl.com. The AI can check your usage and limit at any time.
