Nabu.Mcp.AspNetCore turns ASP.NET Core APIs into MCP tools

Nabu.Mcp.AspNetCore is a new library that allows developers to expose their existing ASP.NET Core Web APIs as Model Context Protocol (MCP) tools. This integration requires minimal code changes, often just a single attribute applied to controller actions or Minimal API route handlers. The library ensures that all standard ASP.NET Core features like authentication, authorization, validation, and middleware are preserved during tool calls, as each call is processed through the application's full HTTP pipeline. AI

IMPACT Enables developers to leverage existing web APIs as AI-accessible tools without extensive refactoring.

RANK_REASON This is a new software library release that integrates existing web APIs with a specific protocol, rather than a core AI model release or significant industry event.
