SUMMARY
MCP Playground is a web-based tool for inspecting and testing Model Context Protocol (MCP) servers, allowing developers to explore and debug integrations without desktop apps or CLI tools. It offers interactive execution of server-exposed tools, resources, and prompts, with full visibility into request/response logs. The platform supports secure connections via OAuth and AES-256-GCM encryption. Open-source under the MIT license, MCP Playground is developed by Emergent Labs and is freely available to enhance MCP tooling.
