1. **Install uv** (Python package manager): ```bash brew install uv ```
bash brew install uv . That is what the vastai mcp mcp server brings to an AI assistant: the same capability, reachable through the Model Context Protocol rather than a separate app or dashboard.The server publishes 3 tools. What each one is for:
Prerequisites — 1. Install uv (Python package manager): bash brew install uvConfiguration — 1. Get your Vast.ai API key: - Log in to console.vast.ai - Go to Account > API Keys - Create or copy your API keyTroubleshooting — The Troubleshooting tool exposed by this serverConfiguration is passed through the environment: VAST_API_KEY, SSH_KEY_FILE, SSH_KEY_PUBLIC_FILE, JUPYTER_ENABLE_LAB. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
wandb on PyPI is all you need. Most clients run it directly, so configuration is a few lines and a restart.
This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Vastai MCP's toolset — Prerequisites, Configuration, Troubleshooting — is a fair guide to whether it matches your workflow. It is maintained by CryDevOk; worth a glance at recent repository activity before you build anything load-bearing on it.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
