Practical Implementation

How to Build, Test, and Deploy MCP Apps with Real Tools and Workflows

(Click di image above to watch di video for dis lesson)

Practical implementation na where di power of Model Context Protocol (MCP) go start to make sense. Even though to sabi di theory and architecture wey dey behind MCP dey important, di real value go show when you use di concepts build, test, and deploy solutions wey fit solve real-life problems. Dis chapter go help you move from just sabi di idea to actually do di work, and e go guide you on how to bring MCP-based apps to life.

Whether you dey develop smart assistants, dey put AI inside business workflows, or dey build custom tools for data processing, MCP dey give you flexible foundation. E no dey tied to any language, and e get official SDKs for popular programming languages, so e dey easy for plenty developers to use. With these SDKs, you fit quickly prototype, test, and scale your solutions for different platforms and environments.

For di sections wey dey follow, you go see practical examples, sample code, and deployment strategies wey go show you how to use MCP for C#, Java with Spring, TypeScript, JavaScript, and Python. You go also learn how to debug and test MCP servers, manage APIs, and deploy solutions to di cloud with Azure. All these hands-on resources dey designed to make your learning fast and help you build strong, production-ready MCP apps.

Overview

Dis lesson go focus on di practical side of MCP implementation for different programming languages. We go look how to use MCP SDKs for C#, Java with Spring, TypeScript, JavaScript, and Python to build strong apps, debug and test MCP servers, and create reusable resources, prompts, and tools.

Learning Objectives

By di end of dis lesson, you go fit:

  • Use MCP solutions with official SDKs for different programming languages
  • Debug and test MCP servers well
  • Create and use server features (Resources, Prompts, and Tools)
  • Design workflows wey go make MCP handle complex tasks
  • Make MCP implementations better for performance and reliability

Official SDK Resources

Model Context Protocol get official SDKs for different languages:

Working with MCP SDKs

Dis section go show practical examples of how to use MCP for different programming languages. You fit find sample code for di samples folder wey dey organized by language.

Available Samples

Di repository get sample implementations for di following languages:

Each sample dey show di main MCP concepts and implementation patterns for di specific language and ecosystem.

Core Server Features

MCP servers fit get any combination of these features:

Resources

Resources dey provide context and data wey di user or AI model fit use:

  • Document repositories
  • Knowledge bases
  • Structured data sources
  • File systems

Prompts

Prompts na templates for messages and workflows for users:

  • Pre-defined conversation templates
  • Guided interaction patterns
  • Specialized dialogue structures

Tools

Tools na functions wey di AI model fit run:

  • Data processing utilities
  • External API integrations
  • Computational capabilities
  • Search functionality

Sample Implementations: C# Implementation

Di official C# SDK repository get plenty sample implementations wey dey show different parts of MCP:

  • Basic MCP Client: Simple example wey show how to create MCP client and call tools
  • Basic MCP Server: Small server implementation with basic tool registration
  • Advanced MCP Server: Full server with tool registration, authentication, and error handling
  • ASP.NET Integration: Examples wey show integration with ASP.NET Core
  • Tool Implementation Patterns: Different patterns for implementing tools with different complexity levels

Di MCP C# SDK still dey preview and APIs fit change. We go dey update dis blog as di SDK dey evolve.

API management

Azure API Management na better way to secure MCP Servers. Di idea na to put Azure API Management instance in front of your MCP Server make e handle features wey you go need like:

  • rate limiting
  • token management
  • monitoring
  • load balancing
  • security

Azure Sample

Here be Azure Sample wey dey do exactly dat, creating an MCP Server and securing it with Azure API Management.

See how di authorization flow dey happen for di image below:

APIM-MCP

For di image wey dey above, di following dey happen:

  • Authentication/Authorization dey happen using Microsoft Entra.
  • Azure API Management dey act as gateway and dey use policies to direct and manage traffic.
  • Azure Monitor dey log all request for further analysis.

Authorization flow

Make we look di authorization flow more in detail:

Deploy Remote MCP Server to Azure

Make we see how we fit deploy di sample we mention earlier:

  1. Clone di repo

    git clone https://github.com/Azure-Samples/remote-mcp-apim-functions-python.git
cd remote-mcp-apim-functions-python

  2. Register Microsoft.App resource provider.

    • If you dey use Azure CLI, run az provider register --namespace Microsoft.App --wait.
    • If you dey use Azure PowerShell, run Register-AzResourceProvider -ProviderNamespace Microsoft.App. Then run (Get-AzResourceProvider -ProviderNamespace Microsoft.App).RegistrationState after some time to check if di registration don complete.

  3. Run dis azd command to provision di api management service, function app (with code) and all other required Azure resources

    azd up

    Dis command go deploy all di cloud resources for Azure

Testing your server with MCP Inspector

  1. For new terminal window, install and run MCP Inspector

    npx @modelcontextprotocol/inspector

    You go see interface wey resemble:

    Connect to Node inspector

  2. CTRL click to load di MCP Inspector web app from di URL wey di app display (e.g. http://127.0.0.1:6274/#resources)

  3. Set di transport type to SSE

  4. Set di URL to your running API Management SSE endpoint wey azd up display and Connect:

    https://<apim-servicename-from-azd-output>.azure-api.net/mcp/sse

  5. List Tools. Click on one tool and Run Tool.

If all di steps work, you suppose don connect to di MCP server and you don fit call one tool.
