Claude Desktop can use a third-party inference gateway when developer mode is enabled. Choose the setup path based on your LLMEasy Key group: enter the Anthropic-compatible endpoint directly, or forward requests through a CC Switch local route.
If you use an API key from the Claude Key group, you can enter https://www.llmeasy.ru directly in Claude Desktop. If you use an API key from the GPT Key group, configure a local route through CC Switch first, then enter the local service address in Claude Desktop. Do not enter the Codex / OpenAI-compatible endpoint https://www.llmeasy.ru/v1 directly in Claude Desktop Gateway.
