On the MX Junos cli the connection would need to connect from the routing instance where server you are attempting to connect has a route.
example:
ssh x.x.x.x interface lo.x routing-instance name
The connection then sources on the MX from inside that routing instance using the loopback as the source address.

thanks for reponses , yes I do have loopback on the specified routing instance ? but i initiate the connection from my localhost -> PE(vrf) -> CE
i tried many command without succes . the question how would you process to give with your ssh command the name of the vrf to use ?
Do i need to activate system services ssh tcp-forwarding ? (20.4R3-S3.4) , activating it does imply security risk ?
thanks

Not sure I follow the configuration but, to use SSH from the MX you need an ip address inside the routing instance in order to source the connection. If there are no interfaces you could create a loopback interface inside the routing instance and specify that as the source.

Hi everybody
I have my local machine from which I want to access a web server located at different clients' sites. The intermediate machine is an MX204 running version 20, and the client's web server is located in a dedicated VRF. How can I specify the VRF via SSH? Or is there a technique to remotely access this web server without having a direct interface in the client's VRF?"
ssh -vv -x -L 443:"ssh USER@X.X.X.X. routing-instance XXXX :443" user@X.X.X.X
Thanks
