Resend MCP vs Klaviyo MCP — different jobs, right?

Both Resend and Klaviyo have MCP servers now. But they feel like they solve different problems. Klaviyo's is about giving the agent access to a rich ecommerce data model and campaign/flow actions. Resend's is more about transactional sending and automations-as-code.

Hot take: is MCP just a wrapper over the REST API?

Genuine question, not trolling. If a platform already has a good REST API, what does an MCP server add other than a different envelope? My agent can already call the API.
