I can attest to everything. Using Tidewave MCP to give your agent access to the runtime via REPL is a superpower, especially with Elixir being functional. It's able to proactively debug and get runtime feedback on your modular code as it's being written. It can also access the DB via your ORM Ecto modules. It's a perfect fit and incredibly productive workflow.

Some MCP's do give the models superpowers. Adding playwright MCP changed my CC from mediocre frontend skills, to really really good. Also, it gives CC a way to check what it's done, and many times correct obvious errors before coming back at you. Big leap.

Is an MCP really required for this?

Which models are you using? I’ve had mixed luck with GPT 5.2.
