Koan MCP Integration

Koan MCP Integration

Core Principle

Expose Koan services as MCP tools for Claude integration. Use framework patterns for tool implementations.

MCP Server Setup

Basic MCP Server

using Koan.Mcp;

var builder = WebApplication.CreateBuilder(args);
builder.Services.AddKoan();
builder.Services.AddKoanMcp(); // Adds MCP capabilities
var app = builder.Build();
app.Run();

Expose Entity as MCP Tool

public class TodoMcpTool : IMcpTool
{
    public string Name => "get_todo";
    public string Description => "Retrieve a todo by ID";

    public McpToolSchema Schema => new()
    {
        Parameters = new[]
        {
            new McpParameter { Name = "id", Type = "string", Required = true }
        }
    };

    public async Task<McpToolResult> ExecuteAsync(
        Dictionary<string, object> args,
        CancellationToken ct)
    {
        var id = args["id"].ToString();
        var todo = await Todo.Get(id, ct);

        return new McpToolResult
        {
            Content = todo != null
                ? $"Todo: {todo.Title} (Completed: {todo.Completed})"
                : "Todo not found"
        };
    }
}

Configuration

{
  "Koan": {
    "Mcp": {
      "ServerName": "Todo MCP Server",
      "Version": "1.0.0",
      "Transport": "stdio",
      "Capabilities": {
        "Tools": true,
        "Resources": true,
        "Prompts": false
      }
    }
  }
}

Code Mode Integration

MCP servers integrate with Claude Code Mode for enhanced capabilities.
