parallel-cli-setup

Instructions for installing and maintaining Parallel CLI, a command-line tool for web searches, extracts, and research tasks. They cover checking its version, installation method, authentication, balance, and skill installation.

In plain words
What is it for?
Use them to check whether Parallel CLI is available, install or upgrade it, authenticate it, inspect account balance, and install related skills.
Why use it?
They help set up the correct CLI version and choose the matching update method instead of guessing how it was installed.

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 A, and why

parallel-cli-setup scanned grade A with 1 finding 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 2d ago.

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.

Parallel CLI Setup

Set up or maintain parallel-cli with minimal friction. If you are running this prompt, your goal is to follow the instructions below and set up parallel-cli for the user so that they can execute searches, run extracts, deep research, etc.

Step 1: Install or upgrade the CLI

Check whether the CLI exists:

command -v parallel-cli

If missing, install with any of these methods:

  1. macOS only: brew install parallel-web/tap/parallel-cli
  2. Linux/macOS/Windows (uv): uv tool install "parallel-web-tools[cli]"
  3. Linux/macOS/Windows (npm): npm install -g parallel-web-cli
  4. Linux/macOS/Windows (pipx): pipx install "parallel-web-tools[cli]" && pipx ensurepath

When parallel-cli is present, require version >=0.9.2. If older, identify the install method before advising an update. Use command -v parallel-cli, then inspect readlink "$(command -v parallel-cli)" if it is a symlink. Paths under ~/.local/share/uv/ tools/ indicate uv tool install; paths under ~/.local/share/parallel-cli/ indicate the standalone installer.

Upgrade commands (choose based on how it was installed):

  • standalone: parallel-cli update
  • uv: uv tool upgrade parallel-web-tools[cli]
  • pipx: pipx upgrade parallel-web-tools[cli]
  • npm: npm update -g parallel-web-cli
  • homebrew: brew update && brew upgrade parallel-web/tap/parallel-cli

Step 2: Authenticate

Check auth status:

parallel-cli auth --json

You will get a response like:

{
  "authenticated": true,
  "method": "oauth",
  "env_var_set": false,
  "has_stored_credentials": true,
  "stored_overridden_by_env": false,
  "token_file": "xxx",
  "version": 1,
  "selected_org_id": "legacy",
  "selected_org_name": null,
  "has_control_api_tokens": false
}

If authenticated is false or selected_org_id is legacy, prompt the user to log in:

parallel-cli login --json

If this is a headless session, append --no-browser.

This triggers device OAuth. The user will be prompted to go to a web browser and input the code the CLI outputs.

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.

parallel-cli-setup is a skill published in the GitHub repository parallel-web/parallel-agent-skills (72 stars, last pushed 18d ago), licensed MIT. It adds 22 tokens to every session and 1,042 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
