The IAB Europe CMP Validator checks web pages for the availability of a TCF registered CMP and facilitates their auditing. The IAB Europe CMP Validator v2.3 checks web pages for the availability of a TCF registered CMP supporting the latest updates to the TCF introduced in IAB Europe's TCF v2.3. It verifies the availability and correct behavior of a TCF-registered CMP that supports the latest updates to the Transparency and Consent Framework (TCF) based on the control catalogue available at https://iabeurope.eu/wp-content/uploads/250412-Controls-Catalogue-TCFv2.2.pdf If no TCF CMP is found on the page, the tool will report “No CMP API found on this webpage. CMP validator cannot operate.”, indicating that the website does not implement a TCF-registered CMP.
