Notes and caveats
- Doppler labels the server experimental and intended for development, testing and evaluation.
- Authenticate with
npx @dopplerhq/mcp-server login(browser-created CLI token stored in the system keyring) or pass a DOPPLER_TOKEN service token or service account token. - Tools are generated from the OpenAPI spec, so the list depends on flags (--read-only, --project, --config); tool names are truncated to 50 characters.
- Requires Node.js 20+.
