Test MCP Server in Browser

What is MCP Playground?

MCP Playground is a free, browser-based testing tool for the Model Context Protocol (MCP). It allows developers to test MCP servers, MCP clients, and MCP tools directly in their browser without any installation or configuration. Whether you're building a new MCP server, testing an existing implementation, or exploring the MCP ecosystem, MCP Playground provides an instant, zero-friction way to interact with MCP servers online.

Our platform supports all core MCP features including tools, prompts, and resources. You can connect to any remote MCP server, browse available tools, execute commands, and view real-time request and response logs. MCP Playground is completely free to use and requires no sign-up or authentication.

Why Use MCP Playground for Testing?

Testing MCP servers traditionally requires setting up local environments, installing dependencies, and configuring connections. MCP Playground eliminates all of this by providing a ready-to-use testing environment in your browser. Simply enter your MCP server URL, and you can start testing immediately.

Our tool is perfect for developers who want to quickly validate MCP server implementations, test MCP tools before deployment, or explore the MCP servers list. The platform works with any standard MCP server that supports remote connections, making it ideal for testing both your own servers and third-party MCP implementations.

How to Test MCP Server in Browser

Testing an MCP server with MCP Playground is straightforward. First, navigate to our MCP server testing page. Enter your MCP server URL in the connection form. If your server requires authentication, you can optionally provide an authentication token. Click connect, and MCP Playground will establish a connection to your server.

Once connected, you'll see a list of available tools, prompts, and resources. You can browse these capabilities, execute tools with custom parameters, retrieve prompts, and access resources. All interactions are logged in real-time, allowing you to see exactly what requests are being sent and what responses are received.
