MCP Server: Tool registration without a real method

[IvanMurzak]

Issue (at MCP Server)

The MCP server doesn't have method to link it into Tools collection. Instead expected to handle the tool manually in McpServerHandlers.CallToolHandler. Just please let to register the new tool without real method.

The issue is fully described right here.

Solution (for MCP Server)

To have IMcpServer.NotifyTooListChanged method. It would request list of tools using the handler that were added earlier using .WithListToolsHandler.

public class McpServer : IMcpServer
{
    public void NotifyToolListChanged()
    {
        // 1. request list of tools from handler
        // 2. notify Client about changes
    }
    // ...
}
public interface IMcpServer
{
    void NotifyToolListChanged();
    // ...
}
