mcp -test

MCP server from xfg-studio/mcp-server-test

Installation
Run this command in your terminal to add the MCP server to Claude Code.
Run in terminal:
Command
claude mcp add --transport stdio xfg-studio-mcp-server-test java -Dspring.ai.mcp.server.stdio=true -jar /Users/fuzhengwei/Applications/apache-maven-3.8.4/repository/cn/bugstack/mcp/mcp-server-test/1.0-SNAPSHOT/mcp-server-test-1.0-SNAPSHOT.jar

How to use

This MCP server entry provides a test instance of an MCP server packaged as a Java application. It runs via the Java runtime and launches the bundled JAR with the Spring-based MCP server configured to communicate over standard I/O (stdio). Once started, the server participates in the MCP protocol used by the surrounding ecosystem, allowing clients to negotiate capabilities, load MCP modules, and exchange commands according to the MCP specification. The test server is useful for validating integrations, testing module messaging, and exercising the MCP runtime in a controlled environment.

To use it, ensure Java is installed and available on your system, then start the server using the provided command. You can monitor startup logs from the console. When the server is running, you can connect an MCP client to the same runtime (stdio in this case implies communication through the process I/O streams). Use your MCP tooling to send capability negotiation, synchronous/asynchronous requests, and module management operations as defined by the MCP protocol. If you have a suite of test modules, you can load and test them against this server instance to verify correct behavior and compatibility with your client tooling.

How to install

Prerequisites:

  • Java Runtime Environment (JRE) or Java Development Kit (JDK) 8+ installed on your system and accessible in your PATH.
  • Access to the test MCP server JAR as specified in the README (the path in the mcp-server-test entry).

Installation steps:

  1. Verify Java is installed: java -version
  2. Ensure you have the MCP test server JAR locally. The README path shows: /Users/fuzhengwei/Applications/apache-maven-3.8.4/repository/cn/bugstack/mcp/mcp-server-test/1.0-SNAPSHOT/mcp-server-test-1.0-SNAPSHOT.jar If you don’t have it, download or build the artifact according to your project’s workflow.
  3. Run the MCP test server: java -Dspring.ai.mcp.server.stdio=true -jar /Users/fuzhengwei/Applications/apache-maven-3.8.4/repository/cn/bugstack/mcp/mcp-server-test/1.0-SNAPSHOT/mcp-server-test-1.0-SNAPSHOT.jar
  4. Confirm the server starts and listen for MCP protocol exchanges via standard I/O.

Notes:

  • The server uses Spring and is configured to communicate over stdio; therefore, it expects consumers to connect through the process’s input/output streams. If you need network-based communication, you may need a different build or configuration.

Additional notes

Tips and common issues:

  • Ensure JAVA_HOME is set and the java executable is on your PATH. Mismatched Java versions can cause classpath or security issues.
  • The path to the JAR in the command may be machine-specific. If you move the artifact, update the path accordingly.
  • When running on systems with strict file permissions, ensure the JAR is readable and executable as needed.
  • If you encounter port/IO issues, verify that the stdio configuration is being honored by your runtime environment. Since this is a test server, it’s common to run in environments where stdout/stderr are captured by the hosting shell or process manager.
  • For debugging, run with additional JVM options (e.g., -Xlog:gc*,level) to capture more details about startup and runtime behavior.
