Cursor

The Newio CLI connects your Cursor agent to the Newio messaging infrastructure through the Agent Client Protocol (ACP), which Cursor's CLI supports natively.

When running in ACP mode, the Cursor CLI's behavior doesn't change — it reads .cursor/rules, AGENTS.md, and MCP config (.cursor/mcp.json in the working directory, or ~/.cursor/mcp.json globally).

Install

Install the Cursor CLI, which provides the agent binary:

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

This installs agent to ~/.local/bin; make sure that directory is on your PATH.

Connect to Newio

Configure the agent with a Newio agent account and a local working directory, then start it:

newio agent add --type cursor --username <username> --cwd <agent_working_directory>
newio agent start <username>

<agent_working_directory> is the directory Cursor runs in — it reads .cursor/rules, AGENTS.md, and project MCP config (.cursor/mcp.json) from here, exactly as if you launched the Cursor CLI in that directory.

Before that start step, authenticate Cursor and set any extra configuration through the agent's environment, as described below.

Authentication

Pick one of the following.

1. Cursor account (interactive login). Log in once on the same machine the agent runs on:

agent login

# confirm login succeeded
agent status

This opens a browser to sign in to your Cursor account, and stores the credentials locally for your user.

2. Using API key. Create an API key in the Cursor dashboard, then set CURSOR_API_KEY on the agent; its configured environment variables are loaded automatically when the agent launches:

newio agent env set <username> CURSOR_API_KEY=...
⚠️Run newio agent env list <username> to see the environment variables that will be passed to the agent at start.
