MCP Playground is an interactive web-based toolkit designed for working with Model Context Protocol (MCP) servers. It enables users to connect to any remote MCP server directly from their browser, browse available tools, resources, and prompts, and execute them live without requiring installation or setup. The platform is built on the official MCP Registry and SDK, and is open source under the AGPL v3 license. Key features include the ability to explore and interact with over 850 MCP servers listed in the official registry, inspect server-exposed tools and resources with full JSON Schema visibility, and run tools in real time using auto-generated forms. Users can connect to servers via Streamable HTTP, Server-Sent Events (SSE), or WebSocket transports, with the system auto-detecting the appropriate protocol. For servers requiring authentication, users can supply their own API keys and authorization headers. The platform also offers an in-browser sandbox that allows running stdio-based npm MCP servers without a backend, leveraging WebContainers technology. MCP Playground provides a schema linter that grades MCP servers from A to F based on over 15 lint rules, checking aspects such as tool descriptions, JSON Schema completeness, and token cost estimates. A quality dashboard presents a registry-wide leaderboard for server quality, with sortable and filterable results and CSV export functionality. A public REST API is available for programmatic inspection, linting, and health-checking of MCP servers, supporting CORS for integration into other tools. Developers can also use the associated CLI and CI tools (mcpx) to enforce quality thresholds and catch regressions in their CI pipelines, with compatibility for GitHub Actions and GitLab CI. The platform is intended for developers, server authors, and anyone working within the MCP ecosystem who needs to test, inspect, or validate MCP server implementations. It also offers embeddable badges for server authors to let users launch live playground sessions directly from documentation. MCP Playground operates entirely in the browser and does not require users to create an account or install software.
MyMCP is a free, open-source application for macOS designed to help users manage Model Context Protocol (MCP) servers. It serves as a centralized solution for discovering, installing, and configuring MCP servers, with particular emphasis on streamlining server management across various AI tools. 0 or later. Key features include a registry browser that allows users to browse and search the official MCP server registry, with the ability to view GitHub statistics such as stars, forks, and recent activity. MyMCP supports one-click installation of MCP servers to multiple clients at once, and users can configure API keys and environment variables during installation. These configurations are securely stored on a per-client basis. The platform also provides comprehensive server management, enabling users to view all installed servers, enable or disable them, and uninstall servers without losing their configuration data. MyMCP is accessible directly from the macOS menubar, offering quick access to server controls and real-time status updates. This design ensures that users can manage their MCP ecosystem efficiently and with minimal interruption to their workflow. The application is distributed under the MIT License and is developed by Just Joshing, LLC. As a dedicated MCP server manager for macOS, MyMCP is positioned for individuals or teams working with Model Context Protocol servers in AI-related environments, providing unified configuration and management capabilities in a single interface.

A production-grade Model Context Protocol (MCP) server for Wireshark
MCP Playground is a browser-based testing platform designed for developers working with the Model Context Protocol (MCP). It enables users to test, debug, and interact with MCP servers, clients, and agents directly from a web interface without the need for local installation or configuration. The tool is positioned as a solution for validating MCP server implementations, testing protocol tools before deployment, and exploring a wide registry of MCP servers. Key features include the ability to connect to any remote MCP server via URL, supporting multiple transport protocols such as HTTP, Server-Sent Events (SSE), streamable HTTP, and local stdio/CLI processes. Users can browse and interact with over 10,000 MCP servers, including those related to platforms such as Supabase, Playwright, Figma, and GitHub. The platform provides real-time JSON-RPC logs for every request and response, allowing developers to inspect protocol interactions, monitor per-call latency, and assess credit costs. Additional tools include an MCP Security Scanner for auditing server security, a token counter, and a configuration generator. MCP Playground offers an Agent Studio, where users can build, test, and deploy MCP-powered AI agents in the browser. This studio allows for running prompts across up to four AI models in parallel, comparing their speed, cost, and accuracy, and exporting agents as production APIs with bearer authentication and server-side locked prompts. The platform supports saving and reusing agent configurations, injecting environment variables for authentication, and provides over 50 ready-to-run templates for rapid prototyping. Users can also access tutorials, recipes, and a prompt library to enhance their development process. The service is completely free to use, with no sign-up or credit card required, and offers free credits for certain features such as the Agent Studio. MCP Playground is aimed at developers, AI engineers, and teams who need to test and validate MCP implementations quickly and efficiently. It removes the traditional barriers of local setup and dependency management, providing instant access to MCP testing tools and resources directly from the browser.
