Common questions

Is ComputeNexa safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: CNX_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed 12 days ago, and the latest version (0.1.0) reached the registry 12 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

ComputeNexa MCP server

Let your AI assistant find, launch and stop private GPUs on ComputeNexa. Ask it *"Which GPUs with 48 GB or more are in stock?"*, *"Launch the cheapest one with Data Science for two hours"* or *"Stop it"*: it uses your team's API key, shows you what each launch costs, and only spends money after you agree.

Works with Claude Desktop, Claude Code, Cursor, VS Code and other assistants that support the Model Context Protocol. It runs on your computer and talks to the ComputeNexa API; your key stays in your own settings.

Set up

In the ComputeNexa dashboard, open API keys and create a key:

Look only to browse GPUs, machines and spending;
Launch and stop to also launch, extend and stop machines.

Install uv (it runs the server with uvx, no separate install needed).
Add the server to your assistant (below), with your key as CNX_API_KEY.

Claude Code

claude mcp add --env CNX_API_KEY=cnxk_... --transport stdio computenexa -- uvx computenexa-mcp

Add --scope user to use it in every project.

Claude Desktop

Settings → Developer → Edit config (claude_desktop_config.json):

"mcpServers": { "computenexa": { "command": "uvx", "args": ["computenexa-mcp"], "env": { "CNX_API_KEY": "cnxk_..." } } } }

Cursor

~/.cursor/mcp.json (every project) or .cursor/mcp.json (one project): the same mcpServers entry as Claude Desktop.

VS Code

.vscode/mcp.json; VS Code asks for the key once and keeps it out of the file:

"inputs": [ { "type": "promptString", "id": "cnx-key", "description": "ComputeNexa API key", "password": true } ], "servers": { "computenexa": { "type": "stdio", "command": "uvx", "args": ["computenexa-mcp"], "env": { "CNX_API_KEY": "${input:cnx-key}" } } } }

What it can do

Tool	What it does	Key
`whoami`	Your email, team, balance, GPU limit and the key's permissions	any
`list_gpus`	GPUs with live prices and stock, cheapest first; filter by app, region, memory	any
`list_apps`	The apps a GPU starts with, their models, and what's installed	any
`list_machines` · `get_machine`	Your machines; how to connect (SSH, browser apps, API or endpoint address)	any
`get_usage` · `list_receipts`	Spending and GPU-hours; finished sessions and their cost	any
`list_projects` · `list_endpoints`	Saved projects; Endpoints and the machine each points at	any
`launch_machine`	Launch a GPU (quote first, then launch when you agree)	launch and stop
`extend_machine`	Add time (quote first)	launch and stop
`set_keep_running`	Renew a machine automatically until stopped (quote first)	launch and stop
`stop_machine`	End a machine now; unused time is refunded	launch and stop
`create_endpoint` · `get_endpoint_key`	A stable HTTPS address for your own server; its key	launch and stop

A look-only key only gets the read tools (the first six rows).

Safety

Nothing is charged without you. launch_machine, extend_machine and set_keep_running first return a quote, e.g. *"NVIDIA RTX A6000 with the datascience app for 2 h: $1.44 charged now ($0.72/h); unused time is refunded if it stops early."* Only a second call with confirm=true and the quoted total goes ahead; if the price went up in between, it's refused.
A limit per call: a launch, extension or keep-running renewal costing more than $25 is refused. Change it with CNX_MCP_MAX_LAUNCH_USD (in dollars) in the server's env. Your team's GPU limit and prepaid balance still apply on top.
Your API key never appears in a tool result. Endpoint keys are shown only when you create an endpoint or ask for its key.
Tools that spend money or end a machine are marked as such, so your assistant asks before using them.

Settings

Variable
`CNX_API_KEY`	Required. A ComputeNexa API key (`cnxk_…`)
`CNX_MCP_MAX_LAUNCH_USD`	Most one call may spend, in US dollars. Default `25`
`CNX_API_URL`	Only for testing against another ComputeNexa API
