CloudGPU MCP Server

Why it got a C

CloudGPU's own MIT-licensed Node.js server (npm cloudgpu-mcp, first published 2026-10-27). It runs on your computer and rents GPUs by the minute from CloudGPU, a prepaid marketplace whose hardware comes from third-party suppliers: get a live quote, rent, upload code and data over SFTP, run commands, read logs, download the results, destroy the GPU. Renting needs a quote and a user_confirmed flag, but the AI sets that flag itself, so keep your client's approval prompt on for create_instance and run_job. The real limits sit on CloudGPU's side: every GPU gets a budget (at most $50 unless you raise CLOUDGPU_MAX_SPEND_USD), a time limit (24 hours by default) and a 60-minute idle shutdown, and your prepaid balance is the hard ceiling. stop_instance and cancel_job destroy the GPU and stop billing. Prefer the connect_account key, which has its own total spend limit, GPU count and expiry, over a full account key; CLOUDGPU_READ_ONLY=1 keeps only the look-up tools. Don't upload anything you wouldn't hand to the GPU's host. No advisories on record. Biggest deduction: run_command and run_job run whatever bash the AI writes, as root on the rented GPU, and download can save files to any folder on your computer.
