# McpToolsClient

## Overview

The `McpToolsClient` component enables Wisej.AI to access and utilize tools provided by an [MCP](https://modelcontextprotocol.io/introduction) (Model Context Protocol) server.

By acting as a communication bridge between Wisej.AI and the MCP server, `McpToolsClient` allows your applications to leverage advanced server-side functionalities defined by the Model Context Protocol.

You can find some public servers here: <https://mcpservers.org/>, <https://mcp.so/>.

## Using McpToolsClient

To integrate the tools from an MCP server with your Wisej.AI objects, simply add an instance of the `McpToolsClient` class, similar to how you would add any other tool container.

```csharp
this.smartPrompt1
    .UseTools(new McpToolsClient("https://remote.mcpservers.org/fetch"));
```

Unlike local tool containers, however, when using `McpToolsClient`, you do not create the tools yourself, nor does the code execute on your machine. Instead, `McpToolsClient` automatically discovers the tools available on the MCP server and registers them with the application model.

## Create MCP Servers

Creating MCP servers is beyond the scope of Wisej.AI. However, there are many public MCP servers available, implemented in a variety of programming languages. If you prefer to develop your own MCP server using C# and ASP.NET, you can use the C# SDK, which is available at <https://github.com/modelcontextprotocol/csharp-sdk>. This SDK provides the necessary tools and libraries to implement an MCP server in a .NET environment.

This is a simple example on how to start the server:

```csharp
var builder = WebApplication.CreateBuilder(new WebApplicationOptions
{
	Args = args,
        WebRootPath = "./"
});

builder.Services
	.AddMcpServer()
	.WithHttpTransport()
	.WithToolsFromAssembly();

var app = builder.Build();
app.MapMcp();
```

And this is a very simple MCP tool:

```csharp
[McpServerToolType]
public class McpToolsServer
{
	[McpServerTool, Description("Echoes the message back to the client.")]
	public static string Echo(string message)
		=> $"hello {message}";
}
```
