Configuration

TENKI_API_KEY*secret

Luxor API key (starts with lx_; tk_ is still accepted). Alternatively set TENKI_AUTH_TOKEN (an ory_st_ session token or session cookie); the header is chosen by token prefix. LUXORAI_* names are read first.

TENKI_API_ENDPOINT

Override the control-plane endpoint. Defaults to https://api.tenki.cloud (the same API as https://api.luxor.ai).

Readme

Luxor MCP: `@luxorai/mcp`

A Model Context Protocol server for Luxor Sandbox, part of Luxor Agent Cloud by Luxor AI. Give any agent (Claude, Codex, Cursor) a disposable microVM it can create, run code in, read and write files, run git, and expose to the web. Sandboxes boot in ~2 seconds and are billed per second.

The agent writes code and Luxor runs it in isolation. (Luxor Code Review and Luxor's managed CI runners are separate products; this server currently exposes the Sandbox.)

The old @tenkicloud/mcp name keeps working and publishes the same code.

"Run this Python in a fresh sandbox and tell me what it prints."
        │
        ▼   tenki_run_code
   boots a microVM → runs it → returns stdout → tears it down

Quickstart

export LUXORAI_API_KEY=lx_your_key_here
npx -y @luxorai/mcp     # speaks MCP over stdio

Nothing to clone or build. The package installs the command luxor-mcp (and tenki-mcp, the same program).
