# What is MCP (Model Context Protocol)?

**MCP (Model Context Protocol)** is an open protocol that lets AI models securely connect to external tools, data sources, and applications through a standardized interface.

Think of it as **"USB-C for [AI applications](https://www.mindstick.com/forum/161494/how-is-natural-language-processing-nlp-used-in-ai-applications)"**: instead of building a custom integration for every database, API, or service, an [AI assistant](https://answers.mindstick.com/qa/116750/building-a-local-ai-assistant-in-dot-net-with-ollama) can use MCP to interact with many systems through a common protocol.

### Why MCP exists

Without MCP:

- Every AI app needs custom code for every tool.
- Integrations are difficult to maintain.
- Switching models or providers often requires rebuilding connections.

With MCP:

- Tools expose a standard MCP interface.
- Any MCP-compatible AI client can use them.
- Integrations become reusable across models and applications.

### How it works

MCP typically involves three components:

- **Host**

   - The [AI application](https://answers.mindstick.com/qa/116696/what-are-the-ethical-concerns-in-ai-application-development) (e.g., an AI coding assistant, desktop app, or chatbot).

- **MCP Client**

   - Embedded in the host.
   - Communicates with MCP servers.

- **MCP Server**

   - Provides capabilities such as:

      - [Database access](https://www.mindstick.com/blog/766/database-access-in-asp-dot-net)
      - File access
      - Git repositories
      - APIs
      - Business systems
      - Custom tools

```plaintext
AI App (Host)
      |
      v
 MCP Client
      |
      v
 MCP Server
      |
      +--> Files
      +--> Databases
      +--> APIs
      +--> External Tools
```

### What MCP servers can provide

An MCP server can expose:

**Tools** – actions the model can perform

- Run [SQL queries](https://www.mindstick.com/forum/159818/how-to-use-the-coalesce-function-to-handle-null-values-in-sql-queries)
- Create tickets
- Call APIs

**Resources** – data the model can read

- Documents
- Files
- Database records

**Prompts** – reusable prompt templates

- Workflows
- Task-specific instructions

### Example

Suppose an AI assistant needs access to a company's customer database.

Instead of writing a custom integration:

- The company runs an MCP server.
- The server exposes a tool like:
- `get_customer(id)`
- The AI client discovers the tool automatically.

The model can request customer information through the MCP interface.

### Benefits

- Standardized integrations
- Model-agnostic architecture
- Better tool discovery
- Easier maintenance
- Improved [security controls](https://www.mindstick.com/interview/23387/what-are-the-asp-dot-net-security-controls)
- Reusable ecosystem of connectors

### MCP and AI coding tools

Many AI [development environments](https://answers.mindstick.com/qa/112053/how-do-i-handle-database-migrations-in-agile-development-environments) and agents now support MCP servers to connect to:

- Git repositories
- Issue trackers
- Documentation systems
- Databases
- [Cloud services](https://www.mindstick.com/forum/34516/cloud-services)

This allows the AI to work with real project context rather than only the text in the chat.

### Who created it?

MCP was introduced by [Anthropic](https://www.anthropic.com/) and has since gained broad adoption across the AI ecosystem, with many AI tools, frameworks, and companies building MCP-compatible [clients and servers](https://www.mindstick.com/forum/160417/how-to-secure-bearer-tokens-during-their-transmission-between-clients-and-servers).

In one sentence: **MCP is a standardized protocol that enables AI models to securely discover and use external tools, data, and services.**
