Overview
What It Does
Sendmux Getting Started packages a focused communication workflow for an AI agent. Sendmux setup, skill installation, API key validation, agent access, secure agent credential-bundle storage, and first-call guidance. Use when the user wants to install Sendmux tooling or skills, check whether an smx_root_, smx_mbx_, or smx_agent_ credential works, choose MCP vs CLI vs SDK, connect an agent to Sendmux email, configure auth, self-register an agent, or make the first harmless Sendmux API call from an agent, terminal, or application. It is best suited to users who can review the resulting actions and provide only the accounts, files, or command access needed for the task. It is not a substitute for human approval on destructive, financial, security-sensitive, or public-facing actions.
