Context is a native macOS client for the Model Context Protocol (MCP), designed to help developers test and debug MCP servers. It offers a visual interface for invoking tools, previewing resources, and monitoring logs, supporting multiple simultaneous connections.

How It Works

Built with Swift and SwiftUI, Context leverages the MCP specification to provide auto-generated UIs for tool invocation based on JSON Schema. It supports dynamic prompt generation and offers built-in resource previews with syntax highlighting and QuickLook. The app handles multiple MCP server connections and supports various transports like stdio and Streamable HTTP, along with OAuth 2.1 authentication.
