Introduction

CofounderOS gives your AI agent the tools to run a company: code and deploys, databases, domains, email, phone, payments, the CRM, and ads. You make the decisions. Your agent does the work and asks before it spends money or sets anything up.

Connect Your Agent

The fastest way is to paste this prompt into your agent's chat. It adds Cofounder, signs you in, and walks you through setup:

Please install the Cofounder MCP:
https://api.cofounder.co/mcp

then please trigger oauth signin and follow
https://app.cofounder.co/mcp-onboarding/skill.md
to onboard me onto Cofounder.

Before company setup, ask whether I want to use an existing GitHub
repository, upload a local folder, or start with a new repository.

To set it up yourself, use MCP or the CLI. Both give your agent the same tools and guides.

• MCP works in Claude, ChatGPT, Codex, Cursor, and VS Code. Add this server URL; there's nothing to install:

  https://api.cofounder.co/mcp

  Copy

• CLI works for agents that run commands in a terminal, and for scripts and CI:

  npm install --global @generalintelligence/cofounder@latest vercel@59.19.0
  cofounder auth login

  Copy

Then tell your agent:

Get started with Cofounder.

It signs you in, finds or creates your company, and suggests a first task. Connect an Agent has a prompt for terminal agents, one-click installs, and setup for each app.

What Your Agent Can Do

Your agent works on every part of the company:

• Start it. Your agent creates the company, learns your pitch and market, and sets up the repository, hosting, database, and inbox in one managed setup run.
• Build and ship. It works on your product's code, deploys it, runs the database, and connects a domain.
• Sell and talk to customers. It sends email, receives texts, keeps the CRM up to date, finds prospects, and books meetings.
• Grow. It runs ads, publishes social posts, improves search rankings, and makes images and video with Media.
• Money and paperwork. It takes payments, tracks spend, and incorporates the company.

Before it acts, your agent reads Cofounder's guides. They tell it what to check first, which steps need your approval, and how to report what it did (How Your Agent Works). You follow along and answer its questions in the dashboard at app.cofounder.co/os.

Company Resources

A resource is something your company uses, like a database, code repository, email inbox, domain, or phone number. Cofounder tracks each one and tells your agent which are ready to use and which need attention.

MCP, CLI, and API

Every operation is available through MCP, the cofounder CLI, and a REST API for your own scripts. Guide pages list all three side by side:

A few commands exist in only one place. auth and doctor, for example, are CLI-only. Pages mark these where they come up.
