Though cppcheck is an open source tool, it supports a number of MISRA checks. This does not make it a certified tool for the validation of conformance to MISRA guidelines but allows you to understand how close your code is to the MISRA requirements and how much effort might be needed to make it compliant.

The MISRA check is implemented as an add-on; you can run it according to the instructions that can be found in the add-ons section of the GitHub repository for cppcheck (https://github.com/danmar/cppcheck/tree/master/addons).
