JMeter MCP Server

Implementation Reference

• jmeter_server.py:132-144 (handler)

  Handler function for the 'execute_jmeter_test_non_gui' MCP tool. Decorated with @mcp.tool() for automatic registration and schema inference from type hints and docstring. Delegates execution to the run_jmeter helper.
