ColorsMCP - Model Context Protocol (MCP) Server

Overview

This is a Model Context Protocol (MCP) server implementation built with .NET 9.0.
Projects are provided to build:

• STDIO
• Http Streamable - Docker Image
• SSE - Azure Function App

Able to ask questions about Colors.

Configuration STDIO

VSCode config

Filename: .vscode\mcp.json

{
    "servers": {
        "colorsserver": {
            "type": "stdio",
            "command": "dotnet",
            "args": [
                "run",
                "--project",
                "c:/dev/ColorsMCP/ColorsMCP/ColorsMCP.csproj"
            ]
        }
    }
}

Configuration HTTP - Docker

Build Docker file

cd <projectroot>
docker build -f colorsmcp-http/Dockerfile -t colorsmcp-http:latest .
docker images

Run Docker file

docker run -p 3000:8080 -p 3001:8081 -d colorsmcp-http:latest

VSCode config

Filename: .vscode\mcp.json

{
   "servers": {
       "colorsserver": {
           "type": "http",
           "url": "http://localhost:3000"
       }
   }
}

Configuration SSE - Azure Function App

Azure Functions

There is a project to build an Azure Function App.

Note that the Url of the MCP Server will be http://xxxxx.azurewebsites.net/runtime/webhooks/mcp/sse.

In addition a key is needed. This is located on Function App | Keys blade and is callled mcp_extension.

The header for this key is called x-functions-key.

VSCode config

The VS Code config would look like:

{
    "servers": {
        "colorsserver": {
            "type": "sse",
            "url": "https://xxxxx.azurewebsites.net//runtime/webhooks/mcp/sse",
            "headers": {
                "x-functions-key": "key"
            }
        }
    }
}
