This release includes the following enhancements:
Initial release date: May 29, 2026
Latest update: 2026.1.3 (August 28, 2026)
MCP Server Extension for AI Agents
A new MCP tool has been added to retrieve modified condition/decision coverage (MC/DC) information for analyzed code. The tool provides details about covered and uncovered conditions and decisions, as well as a precomputed list of test vectors required to achieve 100% MC/DC coverage.
The tool can be used in any LLM-enabled development environment that supports MCP integration, including VS Code. With this extension, AI agents can use the exposed coverage information to generate coverage-driven test cases and prepare overviews or summaries of MC/DC coverage results. See Configuring the MCP Server Extension for AI Agents.
Enhanced Code Analysis and Instrumentation
C/C++ parser has been enhanced to better support modern C and C++ syntax.
Additional Updates
The C/C++test CT TÜV certification for the GoogleTest unit testing framework has been extended to include the following compilers:
- GNU GCC 12.x, 15.x
- Clang C/C++ Compiler v 21.0
