I personally have great success with gptel + mcp + claude (via copilot due to corporate restrictions)

I wrote a short article about how I configured it there: https://her.esy.fun/posts/0029-ai-assistants-in-doom-emacs-3...

One thing I really appreciate with gptel is that it is very easy to switch from Claude to something else like a local llm (via ollama or gpt4all for example). And the interface will be similar.
