What on earth is MCP, and why should I care?
• Thursday, 29th October 2026 •
If you’ve been reading about AI lately you may have spotted three letters cropping up everywhere: MCP. It sounds like something only developers need to worry about, but it’s quickly becoming important for any business that wants AI to do something more useful than answer general questions. So what is it?
MCP stands for Model Context Protocol. It’s an open standard, introduced by Anthropic in 2024 and now supported by a growing number of AI tools, that gives an AI assistant a consistent, controlled way to use other software and read other data. Think of it as a universal socket: instead of building a different connection for every combination of AI and business system, you build one MCP connection and any compatible assistant can plug into it.
Why does that matter? On its own, an AI assistant only knows what it was trained on and what you paste into the chat. It doesn’t know your customers, your stock levels or last month’s sales. Without MCP, the only way round that is copying and pasting, which is slow and easy to get wrong.
With an MCP server in place, you can ask your assistant a plain-English question such as “which of our invoices are overdue by more than 30 days?” and it can look in your accounting system for the answer. Here’s what we typically connect:
Customer records – so replies and summaries are based on what you really know about the customer, not a guess.
Databases and spreadsheets – so you can ask questions about your own figures without writing a single query.
Documents and knowledge bases – so your team can find the answer in the handbook rather than interrupting a colleague.
Internal tools and APIs – so the assistant can do things, such as create a booking or log a support ticket, rather than just talk about them.
Is it safe? It can be, as long as it’s built carefully. We set up MCP servers read-only by default, give the assistant access to only what it needs, log what it does, and ask for human approval before anything is changed. That’s the difference between a clever demo and something you can rely on.
If you’re wondering whether MCP could save your team time, we’d love to talk it through. Often the first connection takes days, not months.
