If "you are welcome" in the question means that someone greets you at the door, indicating that your presence is agreeagle to him/her, then "tu es le bienvenu" is correct (but only if you are on first-name terms with the other person, otherwise use "vous êtes le bienvenu"). "Vous êtes l'accueil" is not a correct French sentence and would translate roughly as "you are the greeting".
If "you are welcome" is the standard reply to someone saying "thank you", then the French equivalent - not the Google automatic translation - is "de rien" or "je vous en prie". Both ways are idiomatic French, the latter being of a more elevated language level. Even if that phrase may sometimes be used in the sense of 'I beg', no French speaker would be mistaken.
You can also use "il n'y a pas de quoi", or "pas de problème", which are equivalents to "not a problem".
Additional answer:
As the response to "merci" (thank you) use "Pas de quoi," pronounced paw-de-kwa, short for Il n'ya pas de quoi meaning "There is nothing (to thank me for)", or "de rien." To welcome someone, use bienvenu. To say "You're welcome to it", use "vas-y" or "allez-y" ("go for it"); for "You're welcome to look around", use libre. Remember that adjectives and verbs in French are modified to suit gender and number.
happy to help you = content/heureux de t'aider
S'il te plait
If you are talking to your friend, you would say, "S'il te plait", but if you were talking to someone in the formal, you would say, "S'il vous plait".
