Run Cursor Agent CLI as a 24/7 Server

Cursor shipped a first-class Agent CLI — same agentic loop, portable binary, installable with one curl. Hosting "Cursor" as a desktop app on a VPS is the wrong shape. Hosting agent on its own always-on Firecracker microVM is the right one: login in a remote PTY, rules in the repo, MCP when you need tools, and a blast radius that ends at the VM wall.

Here's the clean setup on jurniti Cursor Agent hosting.

What Cursor Agent is

Cursor Agent is Anysphere's terminal coding agent. Official install:

curl https://cursor.com/install -fsS | bash

That drops agent (and cursor-agent) under ~/.local/bin, with the real binary versioned under ~/.local/share/cursor-agent/versions/.

Useful entry points:

agent — interactive session in the current workspace
agent login — account auth (NO_OPEN_BROWSER=1 for SSH/remote)
export CURSOR_API_KEY=… — automation / CI
agent --print -p "…" — non-interactive one-shot
agent mcp, agent models, agent status

Settings live in ~/.cursor/cli-config.json. Session auth is separate (do not publish it).

Why Cursor Agent needs its own microVM

Cursor Agent acts. It edits the workspace, can run tools, and can call MCP servers. On a laptop that's your whole home directory. A shared container still shares the host kernel.

jurniti gives Cursor Agent its own Firecracker microVM — own kernel, KVM boundary, one tenant per box. A bad tool call or a poisoned MCP integration stays disposable.

You keep the Cursor relationship. Login or CURSOR_API_KEY stays inside the guest. jurniti is not in the model path and does not mark up tokens.

Most work fits Starter (1 vCPU / 2 GiB). 30-day money-back, workspace kept after cancel per plan terms.

Cursor's cloud agents vs your own microVM

Cursor also sells cloud agents — Anysphere-hosted workers running in their infrastructure. They're good at parallel PR grinding inside Cursor's product; the tradeoff is that the workspace, the schedule, and the box all belong to Cursor. A personal microVM is the other shape: an always-on agent CLI in a box you control — your dotfiles, your cron jobs, your MCP config, persistent between sessions — with a KVM boundary instead of a multi-tenant substrate. If the job is "my agent, my workspace, always on," this is that.

Run Cursor Agent in 3 steps

1. Pick a plan and pay

Starter is enough for most Cursor Agent work. Checkout triggers auto-provision.

2. Your microVM boots with `agent` ready

Ubuntu guest, CLI on PATH, in-browser terminal — no SSH required:

NO_OPEN_BROWSER=1 agent login
# or: export CURSOR_API_KEY=...
cd your-project
agent

3. Put it to work

Add project rules (AGENTS.md / team conventions), wire MCP, use --print for jobs you don't want to babysit. Config survives restarts on the persistent home.

Give Cursor Agent its own microVM

What people run Cursor Agent for

Always-on agentic coding without pinning a laptop
Remote PTY login with NO_OPEN_BROWSER device/code flows
Headless jobs via agent --print
MCP-heavy workflows with secrets that never leave the guest

Snapshot a configured agent into a template — settings and rules, never auth.

Frequently asked questions

What is Cursor Agent?

Cursor Agent is Anysphere's terminal coding agent — the `agent` CLI documented at cursor.com/cli. It is not the Electron IDE; it is a shell-first agent with login, models, MCP, plugins, and non-interactive `--print` mode.

Can I run Cursor Agent on a server?

Yes. Install with `curl https://cursor.com/install -fsS | bash`, put `agent` on PATH, and log in with `NO_OPEN_BROWSER=1 agent login` on remote PTYs (or set CURSOR_API_KEY). jurniti boots a microVM with the CLI pre-installed and an in-browser terminal.

Do I need my own Cursor account?

Yes. jurniti is bring-your-own-credentials. Use `agent login` or `CURSOR_API_KEY`. Auth lives in your VM under ~/.cursor/; traffic goes to Cursor's backend. jurniti never resells model tokens.

Why a microVM instead of my laptop?

Cursor Agent can edit files, run shell tools, and call MCP servers. On a laptop the blast radius is your whole machine. On jurniti it gets its own Firecracker microVM with a KVM boundary — rebuild in seconds if something goes wrong.

How much does managed Cursor Agent cost?

Plans start at $25/mo ($250/year — two months free), with a 30-day money-back guarantee. Cursor Agent fits Starter (1 vCPU / 2 GiB) for most work. Your Cursor/model spend is separate and never marked up.

Is this an official Cursor product?

No. jurniti is independent managed hosting. We install the upstream Cursor Agent binary from cursor.com/install at bake time — no fork — so you run real `agent` with your account.
