AI-driven Performance Engineering

This release includes the following enhancement for AI-driven Performance Engineering.

Area	Enhancement
MCP support	MCP support is now available, providing a standardized and secure way to leverage AI-driven natural-language prompts to streamline and automate performance engineering workflows. Using Copilot in Microsoft Visual Studio Code, natural language can be used to interact with the DevWeb MCP server to perform common tasks such as: Record a DevWeb script. Generate a DevWeb script from a HAR file. Generate a DevWeb script from a Swagger file. Run DevWeb scripts in Single mode, Single mode with iterations, or Load mode. For details, see MCP integration.
