MCP Server

What is MCP?

MCP is a simple example of a client and server using the Connect API. It demonstrates how to build a Model Context Protocol (MCP) server that exposes Swagger/OpenAPI operations as tools for an AI chat application.

How to use MCP?

Run the server with CONNECT_API_KEY="<your key>" SWAGGER_FILE="swagger.yaml" make server. Then run the client with make client. To see the Swagger integration in action, start a local OpenAPI-compatible server using make ex-starwars and launch the Shiny application with make shiny.

Key features of MCP
