The protocol is designed to be server-agnostic, so you can use this library to connect to any compliant server. - -Tools can be easily exposed for immediate use by `IChatClient`s, because `McpClientTool` inherits from `AIFunction`. - -```csharp -// Get available functions. -IList tools = await client.ListToolsAsync(); - -// Call the chat client using the tools. -IChatClient chatClient = ...; -var response = await chatClient.GetResponseAsync( - "your prompt here", - new() { Tools = [.. tools] }); -``` - -## Getting Started (Server) - -The core package provides the basic server functionality.
