CROSS-CATEGORY: MCP Became the Integration Surface in Four Unrelated Categories in Three Days — Messaging, Content, Recruiting and Agent Governance

Between September 14 and 16, Meta shipped a WhatsApp Business Tools MCP server so Claude, Cursor, Codex or ChatGPT can do account setup, template creation and troubleshooting; Egnyte launched a Context Layer exposed over MCP to 23,000 customers; Workable brought its MCP Server to GA alongside credit-priced recruiting agents; and WSO2 named MCP among the open standards its Agent Manager control plane governs. Four vendors with nothing in common — social messaging, enterprise content, HR, and platform governance — all chose MCP over building another point integration or another UI. The practical read for builders: the integration marketplace, the thing that was a SaaS moat, is collapsing into a protocol any agent can enumerate.
