The server is started by the client (Claude Desktop / Claude Code), not by this UI — it speaks over stdin/stdout. This page helps you wire it up and proves that the server runs.
pip install deepl-i18n[mcp]deepl-i18n-mcp is not on your PATH — the snippet below
starts the server through the Python interpreter instead.
A bare command name ("command": "deepl-i18n-mcp") does not work in the client:
it starts the process without the activated venv and cannot find the file. In your own terminal it works —
which is what makes this error so confusing. Use the absolute path:
{{ st.snippet }}
cwd can be omitted if the client starts in the project folder anyway
(e.g. Claude Code in this directory).
