Jeff thanks you for helping me with use credentials-helpers with 
git-remote
I will try to code your proposed solution.
making something like that:

+-----+ -----> +----------------------+
| git |  pipe  | git-remote-mediawiki |
+-----+ <----- +----------------------+
                      /\      ||
                      || pipe ||
                      ||      \/
                  +----------------+ ----->  O
                  | git-credential | <----- -|-
                  +----------------+        / \
                      /\      ||            User
                      || pipe ||
                      ||      \/
                  +-------------------------+
                  | git-credentials-helpers |
                  +-------------------------+
