MCP enables you to run a lightweight test server alongside client scripts to validate server behavior and client interactions. It helps you verify the server is reachable, inspect its status in a browser, and test command execution flows between a client and a server in a controlled environment.

How to use

You can quickly test the MCP server and its interaction with a client by following these practical steps. First, start the MCP server using the provided server script and then, from another run, execute a client that talks to that server. You can inspect the running server in a web browser to confirm it is active, and you can observe the client-server interaction as commands are executed.

How to install

Prerequisites you need are the runtimes used by the tests and access to the MCP command runner in your environment. You will use the following commands exactly as shown to exercise the test scenarios.

mcp dev src/servers/server.py

python src/clients/client.py src/servers/server2.py

Additional sections

Scenario 1 focuses on verifying basic MCP server functionality by running the server script and using the MCP inspector in your browser to confirm the server starts correctly. You can expect to visit a local inspector URL such as the example under the same localhost environment, and you may need to provide an authentication token if prompted by the inspector.

Scenario 2 tests the interaction between a client and a server that can execute shell commands. You run a client script that communicates with a server script capable of executing commands. This setup helps you validate end-to-end behavior of client-triggered server actions.

Available tools

Inspector

Web-based MCP inspector used to verify that the server is running and reachable in a browser.

Client-Server Executor

Test flow where a client triggers shell commands on a server, validating end-to-end interactions.
