You asked what the difference is between Luca Express and just an MCP server (Model Context Protocol, the open standard for connecting an AI to your systems) with Claude. We build Luca Express, so read our answer knowing that.
Claude with an MCP server gives you the intelligence and an open, standard way to connect it to the systems you already run. If you have a CRM, a phone system and someone to write, host and maintain the connectors, that is a complete answer, and it is the cheaper one. We deploy Claude this way for clients, and two of the four situations on this page are answered by Claude alone.
Luca Express is the rest of the system, already assembled and run by us: one web workspace; a CRM with email, calendar, tasks and contacts; phones on real numbers with an AI that answers incoming calls; sales workflows that start when something happens in the CRM, such as a completed call; and one connection to Claude and to other AI models. We checked each of those against the running code and its tests on September 15 and 16, 2026. They are real. Our own tasks, email and phones run on them every day.
Not everything is ready, and you should not buy on the strength of these today. Time-delayed follow-ups: Luca Express can queue a callback for later, but nothing runs that queue on a schedule yet, so a follow-up starts when an event triggers it, not by the clock. Outbound AI calling: built, and switched off in every configuration we ship. Governance: controls over who may do what, spend limits and a person approving sensitive actions are early access; Claude Enterprise is ahead of us there, and if audit trail and access control decide your purchase, choose it. Our own MCP side: the gateway that lets your Claude use Luca's tools is early access, and a central hub for other MCP servers, such as GitHub, Jira or Slack, is designed, not built.
Where that leaves you. If your team is technical, or you like the tools you already have, take Claude and MCP and skip us. If you want AI working the phones, the inbox and the pipeline without hiring an engineer to build and keep the connectors, Luca Express is that. The way in is a paid pilot on one workflow with a measurable target, and the format of your data export agreed before we start.
Everything above describes the code as it runs, not a roadmap. The table further down this page carries the same labels, and we will change them when the code changes.
