La Growth Machine for AI agents

La Growth Machine is a multi-channel outreach tool sales teams use to automate LinkedIn and email prospecting sequences and track replies in one place. Connect it once through Arc0, and your agent, or Claude, ChatGPT and Cursor, can use it through one MCP endpoint, limited to what each user approved.

Q01
