Overview
The Massed Compute MCP server lets AI assistants like Claude, Cursor, Codex, and ChatGPT interact with your Massed Compute account on your behalf — listing GPU inventory, launching and managing instances, auditing billing — all using the same API key you'd use from a script.
Set up your client
Pick your AI client below, paste the config, and you're connected. Every snippet uses MC_TOKEN as a placeholder — substitute the API token you copied from vm.massedcompute.com/settings/api.
Tools reference
The MCP server exposes 14 tools. The columns below show which API key tier sees each tool in the assistant's tool list. Use a read-only key when the assistant only needs to read your account state; use a full-access key when it needs to launch, restart, terminate, or manage SSH keys. Tools that a read-only key cannot see are hidden from the assistant entirely — they cannot be invoked accidentally or by prompt injection.
Agent Skills
Agent Skills are markdown files you can drop into your AI assistant. They turn the raw MCP tools into well-paved workflows — picking the right GPU for a workload, launching VMs safely with the right pre-flight checks, auditing spend, and cleaning up.
