QuickMCP MCP Server

What is QuickMCP?

QuickMCP is a .NET toolkit for building and serving Model Context Protocol (MCP) servers from OpenAPI, Swagger, or Google Discovery specifications. It reduces boilerplate and accelerates server creation using a CLI utility and a configurable library.

How to use QuickMCP?

Install the CLI tool with dotnet tool install -g QuickMCP.CLI or add the QuickMCP NuGet package. From the CLI, use commands like quickmcp serve --spec-url to serve a spec, quickmcp build config to generate configuration, or quickmcp build ce to create a Claude Desktop extension. Programmatically, build server info using McpServerInfoBuilder and integrate with the official MCP C# SDK via WithQuickMCP().
