# Install

> Add the Heliyos MCP server to Claude Code, Codex, Cursor or VS Code in a minute.

Every client runs the same command, `npx -y @heliyos/mcp`, with your key in the `HELIYOS_API_KEY` environment variable. Replace `YOUR_HELIYOS_API_KEY` in the snippets with your key.

> [!WARNING]
>
> Config files that hold the key in plain text are as sensitive as the key. Keep them out of shared folders and repositories. Where a client can read the key from your environment or a secret store, prefer that.

Works with every MCP client. Pick yours.

## Check it works

Ask your agent: *"Which Heliyos workspace am I connected to?"* It should call `heliyos_organization_get` and answer with your workspace's name. If it does not, see [Troubleshooting](https://docs.heliyos.ai/mcp/troubleshooting.md).
