The persistent framing of MCP as 'an API for AI' misses the real story. The app-to-app integration problem has existed for decades, but we never had a flexible enough glue to solve it generically. LLMs finally became that glue — a layer capable of mapping one app's domain onto another's on the fly. MCP is the wire format that lets any app plug into any AI host without knowing which host it will meet.
