Hey Product Hunters 👋
We built MCP Playground to solve a simple problem: testing MCP servers shouldn’t require downloading desktop apps, running CLI tools, or asking an LLM to tell you what the MCP server does:
Our solution:
A web-based tool where you can connect to any MCP server and immediately see what it exposes — tools, resources, and prompts. Execute them interactively, view request/response logs, and understand exactly what’s happening.
Key features:
Zero setup — Open your browser and connect
Full visibility — See and test everything the server exposes
Secure — OAuth support with AES-256-GCM encryption
This is open source (MIT license) from Emergent Labs, an AI native product studio building AI-native products. We’re making this freely available because good tooling benefits everyone working with MCP.
Give it a try and let us know what could be better. We’re taking feedback seriously as we shape what comes next.
Thanks for the support! 🙏
