What does the `deploy` tool do?

The `deploy` tool scans your project directory for Dockerfiles and `compose.yaml` files, then deploys the detected service(s) using Defang. Deployment progress can be monitored in the Defang Portal.

How do I set up the Defang MCP Server?

Run `npx -y defang@latest mcp setup --client= ` for your preferred IDE, then start the server with `npx -y defang@latest mcp serve`.

What credentials does it need?

It reads `DEFANG_ACCESS_TOKEN`, `DEFANG_AWS_APN_ID`, `DEFANG_MODEL_ID`, `PULUMI_ACCESS_TOKEN` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.
