Create an audience

Create an audience

Saves a live contact segment from a name and a set of field filters and returns the audience.

Set up

Use the first option your agent supports.

MCP (official, remote)

Add this server to your agent's MCP settings, then sign in when asked.

{ "mcpServers": { "brew": { "url": "https://brew.new/api/mcp" } } }

Call the MCP tool create_audience.

Server URL: https://brew.new/api/mcp

CLI (official)

Install the command, then confirm it runs.

brew install getbrew/tap/brew-cli
brew-cli --version

Run brew-cli audiences create.

Set $BREW_API_KEY in your environment first (get a key: https://brew.new/settings/api).
