Installation

Prerequisites

• Node.js (v18 or higher)
• npm or yarn

To install the AgCel CLI globally, run:

npm install -g agcel

This makes the agc command available globally. If you are developing AgCel locally, you can run npm install -g . from the project root.

Once installed, the CLI can run in a “Global Mode” even without a project-specific setup, using built-in skills and workflows.

While AgCel works globally, you can initialize it in a specific project to customize its behavior:

agc init

This command copies default workflows to your project’s .agent/workflows directory and skills to .agc/skills. When running inside a project initialized this way, AgCel will prioritize these local resources.

Next Steps

Once installed, simply open your project in the Antigravity IDE. The IDE will automatically detect and start the AgCel MCP server for you.

You can verify your skills and workflows using the discovery commands:

agc skills list

To remove AgCel from your system and clean up configuration, run:

agc uninstall

This command will:

1. Remove AgCel from your mcp_config.json.
2. Optionally delete the global data directory at ~/.agcel.
3. Prompt to run npm uninstall -g agcel for you.
