I have a Mauritian passport and a biometric residence permit valid for 2 years. What do I need to visit family member in France for just a week in August.
Mauritian citizens do not need a visa to enter the Schengen area as a tourist for up to 90 days in a period of 180 days https://ec.europa.eu/home-affairs/sites/homeaffairs/files/what-we-do/policies/borders-and-visas/visa-policy/apply_for_a_visa/docs/visa_lists_en.pdf
On arrival in France you must be able to show various supporting documents at the request of the Border Police, including a valid passport issued less than 10 years before and valid for at least 3 months after the envisaged departure date, proof of accommodation covering the whole duration of the stay, sufficient financial means, and return ticket or the financial means to acquire one at the envisaged return date. https://france-visas.gouv.fr/web/france-visas/que-faire-apres-mon-arrivee-en-france
