Historical note · September 2026 · Describes Brew MCP 2.0 as of
September 2026. For the current tools, see MCP Tools.
What Shipped
Brew MCP 1.0 mirrored the API, one tool per call. Asking “how did last week’s send do?” meant choosing between four analytics tools before the assistant could answer. Brew MCP 2.0 reorganized the server around the jobs agents actually do. The catalog went from 89 tools to 79. Each tool covers a task, such as reading a send’s results. Options replace what used to be separate tools.Fewer Tools, Each With One Job
Design tools dropped the extra word:
create_email_design became
create_email, and edit_email_with_ai became edit_email.
For Agents Already Connected
Tool names changed, so prompts or scripts that named 1.0 tools needed new names.get_brew_capabilities lists the live catalog, so an agent that calls
it first finds the right tool on its own.
