I keep seeing MCP discussed as though every business needs to rush out and build one. That is a poor place to start. The useful question is whether a customer or employee has a job that an AI assistant could help with if it had a safe, well-defined connection to your business.
MCP stands for Model Context Protocol. In ordinary terms, it is a shared way for an AI host to discover and use capabilities supplied by another service. A server might expose a few tools, such as looking up an approved service description or checking a project status. The assistant can request those tools when the user asks; the server handles the defined operation and returns structured information.
Think of an assistant that knows how to help prepare an enquiry but has no current knowledge of your availability or service boundaries. Written instructions can explain the process, but current records live elsewhere. An MCP connection can provide a controlled route to that information. It does not give the model a master key to your systems. The server should expose only the operations the business has chosen, with authentication, access rules, and human confirmation for consequential changes.
Start with the work, then choose the connection
For a small firm, useful candidates might include checking a published catalogue, retrieving a policy, or preparing a draft from a customer's supplied details. Some needs do not call for MCP at all. If the assistant only needs reusable guidance, a written skill or plugin may be enough. If people can do the task more easily in an existing form, a new integration adds cost without solving much.
Our short Brownsmith article on MCP for service businesses makes this distinction: reusable business instructions help the assistant approach work consistently; MCP becomes relevant when it needs current information or a defined action. Our MCP implementation article describes how we think about fitting a narrow server around an existing system.
There is also a practical reason to be cautious. The connected AI product decides how people discover and use an integration, and the interface varies by client. A successful connection does not promise a public listing, new leads, or sales. It gives a supported client a route to the capabilities you have deliberately exposed.
A sensible first version
Write down one repeated request, who is allowed to make it, what information the answer needs, and what must never happen without a person. Then check whether your current software can provide that answer reliably. Keep the first tool narrow enough that someone can explain it without a diagram. If the source data is wrong, fix that before connecting anything.
