setup

A command that checks whether the local Cursor command-line tool is installed and signed in, and can turn the stop-time review gate on or off.

In plain words
What is it for?
Checking Cursor setup, identifying missing installation or authentication, and changing the optional review setting.
Why use it?
It shows what must be fixed before Cursor can be used and preserves the required installation or login guidance.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

setup scanned grade C with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Downloads and executes remote codehighSupply chain

curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.

- If the result says `cursorAgent.available` is false, tell the user to install the Cursor CLI manually, for example `curl https://cursor.com/install -fsS | bash` (macOS/Linux), then rerun `/cursor:setup`. Do not auto-ru

Not a fault in itself. Listed so you know the mod talks to something, and to what.

What it actually says

Run:

node "${CLAUDE_PLUGIN_ROOT}/scripts/cursor-companion.mjs" setup --json $ARGUMENTS

Output rules:

  • Present the final setup output to the user.
  • If the result says cursorAgent.available is false, tell the user to install the Cursor CLI manually, for example curl https://cursor.com/install -fsS | bash (macOS/Linux), then rerun /cursor:setup. Do not auto-run a network installer for them.
  • If cursorAgent.available is true but auth.loggedIn is false, preserve the guidance to run !cursor-agent login, or to set CURSOR_API_KEY for headless use.
  • Do not attempt to fix anything else.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

setup is a command published in the GitHub repository Armert-Labs/cursor-plugin (3 stars, last pushed 2mo ago), licensed MIT. It adds 16 tokens to every session and 207 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
