People are starting to ask AI assistants to do things, not just answer questions: book the appointment, compare the options, get the quote. A business with an MCP server can be used directly inside those conversations. A business without one can only be described.
Holston AI's public MCP server at holstonai.com/mcp-server has 12 tools that anyone can use from ChatGPT, Claude, and other assistants, including an AI visibility audit, a missed-call cost calculator, an AI agent designer, and an instant quote builder. It is listed in the official MCP Registry. We build client servers the same way.
An MCP server gives an AI assistant real abilities, so security is designed in from the first day: the fewest permissions each tool needs, input checking, rate limits, protection against prompt injection, confirmation before anything is changed or sent, and logs of every call. We follow the OWASP guidance for secure MCP server development.
A free call to pick the first tools that are worth building, then a fixed-price build, usually 2 to 4 weeks. You get the source code in your own repository, hosting in your account or ours, and usage reporting so you can see which tools people actually use.

Questions
MCP, the Model Context Protocol, is an open standard for connecting AI assistants to outside tools and data. An MCP server is the connector your business runs, so an assistant like ChatGPT or Claude can use your tools, such as checking availability or building a quote, with permission.
ChatGPT apps are built on MCP and add a user interface inside ChatGPT. One well-built MCP server can power a ChatGPT app, a Claude connector, and Copilot agents.
It can be when it is built carefully. Each tool gets only the access it needs, people sign in with their own accounts, anything that changes data asks for confirmation, and every call is logged.
It depends on how many tools you need and which systems they connect to. We agree a fixed price after a free call. There is no hourly billing.
Yes. Add Holston AI's public MCP server to ChatGPT or Claude from holstonai.com/mcp-server and try the tools yourself.
