Introduction to the C# SDK for Model Context Protocol (MCP)

Let's take a look at the official C# SDK for the Model Context Protocol, enabling .NET applications, services, and libraries to implement and interact with MCP clients and servers.

Connect with .NET:

#dotnet #csharp #mcp #mcpservers

Fantastic video! I prefer these short and to the point type videos without extra fluff. I didn’t know you could test MCP using a local file this way and that makes this workflow so much easier. 🤙🏽

Today I've got a server up and running and made some tools to call our API endpoints. This is powerful.
Thanks for the introduction.

This is great. Took me some time to understand how to define the MCP server config in Cline, which doesn't supply all necessary user environment variables. If you're interested, those are the required ones to do "dotnet run --project <proj>.csproj":
`HOME`, `ProgramFiles`, and `AppData`. Add then under "env" in cline_mcp_settings.json` and Cline will load your C# based MCP server. Cheers!

This is such a god sent thank you James

Clear and straight to the point. Thank you!

I'm sick and tired of seeing Python in everything AI-related. C# is and will always be my favorite language.

[MuraliKrishnan-en]

Looking forward more videos on c# mcp with real yime examples

[ianneko]

Nice! Pls continue to improve on AI integration. Such as private corporte use MCP server deployment, agents interaction, monitoring, secruity, testing, multi-agents systens... etc. And think about MCP clients everywhere.
Hopefully building strong AI business use cases using C# or .NET ecosystem.

Nice explanation. Can you create a series on this topic?

Does this in any way obsolete Semantic Kernel? Not seeing why this is necessary if SK exists, do they overlap in functionality?

[johncross]

5:23 What can I do if my mcp.json file doesn't have the "Start" button like yours does?

[ugochukwuumerie]

This is awesome! Can it work with semantic kernel?

[cuachristine]

James. Build a sample MCP, deploy it to a web server, then connect it to Claude or VSCode, then connect to it remotely. And for extra credit, secure the MCP server.

[dikeshkumar]

This is awesome. I have on question can we create a web api and add it as http endpoint instead. I tried, someone it fails to load the tools as it can't fetch

[goodstas]

Thank you for the video. please, may you provide the example how i can create my MCP client which can connect through OpenAI or OLAMA to the LLM and use the server from your example?

[Теодор_Иванов]

Is it necessary to install any extension? When I add mcp.json and click 'Add Server', then describe everything in the JSON, the Run | Stop | Restart options do not appear

[ananthub]

Does the C# SDK support streamable http for mcp server?

[kiranreddy]

how can we deploy the mcpserver in iis once deployed how can i consume the application

[joegopher]

How can we build our custom MCP host to host our clients and servers?

[RemDemo]

James it would help to provide a high level explanation of how MCP fits into existing tools API that LLMs can currently use. Steve Sanderson also recently mentioned MCP but didn't give enough context either about what it adds on top of existing tools API use. It this about self discovery of tools via published Metadata? Or is it a newer better architecture compared to existing tools apis?
