# What Is an MCP Server? A Plain-Language Explainer | Thara

URL: https://www.tharamcp.com/en/resources

What an MCP (Model Context Protocol) server is, how it differs from a regular API, and how Thara uses one to connect your PMS, POS, and ERP systems to AI — read-only, in plain language.

What Is an MCP Server?

The technology behind Thara, explained without the jargon.

"MCP server" is a term you'll increasingly see attached to AI tools. Here's what it actually means, how it differs from a regular API, and how Thara uses one to connect your business systems to AI safely.

## MCP Server: The Short Answer

### Paragraphs

- An MCP server is a small, focused program that lets an AI assistant — like Claude — ask real questions about a specific system, instead of only working from text you paste in. "MCP" stands for Model Context Protocol, an open standard published by Anthropic in 2024 for exactly this purpose: giving an AI a safe, structured way to read data from an external system.
- Thara is an MCP server. It sits between your business systems — PMS, POS, accounting, ERP — and any MCP-compatible AI assistant, and answers questions about your real data without ever modifying the source system.

## MCP Server vs. API

### Paragraphs

- An API is built for developers: it needs code, authentication logic, and a request written in the exact shape the API expects. An MCP server is built for AI: it describes its own capabilities in a way a model can read and call directly, in plain language, without a developer writing custom integration code for each new question.
- Practically, that means an MCP server turns "can I ask AI about my hotel's occupancy this month" from a software project into a sentence.

## Examples of MCP Servers

### Paragraphs

- MCP servers exist for all kinds of systems — file access, code repositories, databases, and increasingly, business software. Claude, ChatGPT, and other MCP-compatible assistants can connect to any of them the same way.

### Bullets

- Developer tools — e.g. an MCP server exposing a code repository so an AI can read and search it
- Claude Desktop and other AI apps — connect to any MCP server a business publishes, no custom plugin required
- Thara — a read-only MCP server for hotel PMS, restaurant POS, golf tee-sheets, and accounting/ERP systems

## How Thara Uses Its MCP Server

### Paragraphs

- Thara's MCP server is strictly read-only: it can answer questions about your data, but it can never modify, delete, or write to the systems it connects to. Every question and every answer is scoped by role-based access control, so a staff member only ever sees what they're authorized to see.
- You can try Thara's own public demo MCP server right now, over synthetic hotel and restaurant data, without connecting any real system.
