Motia: Skip the Protocols, Ship the Product (and Still Speak Them When You Must)

TL;DR Motia collapses APIs, AI agents, cron/background jobs and into a single event‑driven step model. Most of the time, formal layers like MCP (Model Context Protocol), A2A (Agent‑to‑Agent), and runtime Tool‑Use are unnecessary—plain JSON events and SDK calls get the job done with much less ceremony. If you do need MCP/A2A to talk to a partner, Motia can emit or consume those packets through a thin adapter step, so you remain interoperable without letting protocol complexity infect your codebase.
