Self-Host Cursor Agent CLI on a Server, 24/7

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 Session auth is separate (do not publish it).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 a real 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.

Run it 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 it 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.
