💻 MCP Usage

Connect to the server using an MCP-compatible client (e.g., Claude Desktop, Cursor, Windsurf)
Send a prompt to the server:

Run JMeter test /path/to/test.jmx

MCP compatible client will use the available tools:
- 🖥️ execute_jmeter_test: Launches JMeter in GUI mode, but doesn't execute test as per the JMeter design
- 🚀 execute_jmeter_test_non_gui: Execute a JMeter test in non-GUI mode (default mode for better performance)

🏗️ MCP Configuration

Add the following configuration to your MCP client config:

{
    "mcpServers": {
      "jmeter": {
        "command": "/path/to/uv",
        "args": [
          "--directory",
          "/path/to/jmeter-mcp-server",
          "run",
          "jmeter_server.py"
        ]
      }
    }
}

✨ Use case

LLM powered result analysis: Collect and analyze test results.

Debugging: Execute tests in non-GUI mode for debugging.
