MCPify

MCPify is a NuGet package that dynamically loads OpenAPI/Swagger specifications at runtime and exposes each API operation as a tool in an MCP (Model Context Protocol) server.

Features

  • Dynamic MCP Tools: Automatically converts OpenAPI operations into MCP tools
  • OpenAPI Version Support: Supports OpenAPI v2, v3.x, and v3.1+
  • Extensible Architecture: Provider-based design for easy customization
  • ASP.NET Core Integration: Minimal and idiomatic integration with ASP.NET Core

Installation

dotnet add package MCPify

Quick Start

using MCPify.Hosting;

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddMcpify(
    swaggerUrl: "https://petstore.swagger.io/v2/swagger.json",
    apiBaseUrl: "https://petstore.swagger.io/v2",
    options =>
    {
        options.ToolPrefix = "petstore_";
        // options.Filter = op => op.Route.Contains("/pet");
    });

var app = builder.Build();

app.MapMcpifyEndpoint();

app.Run();

Running the Sample

A complete sample application is included in the Sample/ directory:

cd Sample
dotnet run
