Perplexity

Headless infrastructure orchestration

Run your CI/CD pipelines without manual intervention. Claude Code uses `create_machine` to spin up environments and `wait_machine` to ensure they are ready for testing. It handles the entire lifecycle of your build, using `delete_machine` to clean up resources once the test suite finishes.

Terminal-based resource monitoring

Pipe your infrastructure data directly into your terminal. Claude Code uses `list_apps` and `list_volumes` to give you a clear view of your current resource usage. You can query the status of any specific component using `get_app` or `get_machine` to debug production issues without leaving your command line session.

Automated security and auth

Secure your terminal sessions by requesting tokens on the fly. Claude Code uses `request_oidc_token` to authenticate against your infrastructure providers. It also manages your certificates using `create_acme_certificate` to ensure all your deployments meet security standards without manual configuration.

Yes, the server is designed for headless use. You can script complex flows like 'stop all machines in this app' by chaining `list_machines` and `stop_machine` in your pipeline.

You can, provided you manage your rate limits. Claude Code can use `extend_volume` to scale storage during high-traffic events, but keep an eye on your API usage logs.

Simply run 'claude mcp list' to verify the server is active. This will display all 28 tools, including `create_lease` and `release_lease`, ready for use in your scripts.

This setup operates entirely through authenticated API calls between your machine and Fly.io. No infrastructure configuration files or environment secrets are transmitted to third parties; the server only processes raw API responses.
