Enhanced Code Coverage
MCP Server Extension for LLM Agents
C/C++test now provides an MCP (Model Context Protocol) Server extension that allows you to smoothly integrate your LLM agents or applications (for example, Copilot) with C/C++test functionality. The C/C++test MCP Server can be integrated within any LLM-based development environment that supports MCP Server integration, including VS Code and other environments. With this extension, an LLM agent can interact directly with C/C++test, providing context-aware guidance and analysis.
This feature allows you to use an AI copilot to:
- Provide guidance and instructions for applying coverage suppressions to specific code sections.
- Retrieve detailed, line-by-line coverage information for analyzed code.
For details, see Configuring the MCP Server Extension for AI Agents.
