As of Wednesday 21 July 2021,

The Mucem in complete safety: from Wednesday 21 July 2021, entry to the museum (for 18-year olds and older) is subject to the presentation of a valid health pass (digital or paper format). With its partner EDU-PHARM, the Mucem is also offering visitors free antigenic tests (at the entrance on the J4 esplanade).
These tests deliver results in 15 minutes and allow validation of a health pass for a period of 48 hours.
