MCP servers: the piece that connects AI to your business

If your team already uses ChatGPT or Claude, you know the feeling: the assistant writes, summarises and answers beautifully… until you ask it about your business. It cannot see your customers, does not know your orders and cannot touch your CRM. Everything ends in copy and paste.

MCP servers exist to remove exactly that wall.

What is an MCP server

MCP stands for Model Context Protocol, an open standard created by Anthropic in late 2024 and adopted since then by the main AI providers, including OpenAI. It defines a common way to connect AI assistants to real systems: databases, CRMs, ERPs, email, calendars or any internal tool.

The classic analogy is USB-C. Before, every integration between an AI and a tool was a proprietary cable: connecting the assistant to the CRM was one project, to the ERP another, and switching assistants meant redoing everything. With MCP there is a single connector: you build one MCP server for your system and any compatible assistant can use it.

In practice, an MCP server exposes two things, always under your rules:

• Data the AI can query: customers, orders, invoices, stock, documentation.
• Actions the AI can execute: create a quote, update a record, schedule a reminder.

Internal use: your team operates systems in plain language

The highest-return case today is internal. Your team stops navigating menus and forms: they ask in plain language and the assistant does it in the real system.

A real example, the same one we show on our website. You open Claude and type:

"Create a quote for client Martí and mark it as sent."

Through the MCP server connected to the CRM, the assistant creates the quote with your rates, links it to the client and updates its status. No opening the CRM, no templates, no copy and paste. The person who asked never leaves their conversation, and the action is logged like any other.

External use: your services, available to other assistants

The other side is exposing part of your business outwards. An external MCP server lets customers or partners check your catalogue, an order status or your availability from their own AI assistant, with authentication and limits you control.

As more people ask ChatGPT or Claude before they ask Google, having an MCP door will be like having a website or an API: the channel through which your customers' AI talks to your business.

What your company gains in internal workflows

• Less context switching. Query and act without juggling five tabs.
• Data within everyone's reach. "How much did we invoice client X in 2025?" stops requiring an ERP expert.
• Less training. Knowing how to ask replaces knowing every menu.
• Control and traceability. You decide what the AI can read and do, with per-tool permissions and a log of every action.

The typical result: minute-long tasks become seconds, and "when I get a moment" tasks simply get done.

How to get started

At Mitteva we design and build custom MCP servers on top of what you already use: your CRM, your ERP, your databases or that internal tool only one person truly masters. We start with one concrete, measurable use case and grow from there.
