No currently available spacecraft can make the trip and service JWST, it's also not really intended to be serviced.

  Spaceship might (Elon time) fly this August.

    It's "Starship", and it's unlikely to be able to get to where the JWST is in the next few years due to needing to be refuelled in orbit. Plus they have no payload bay design. Then there's the robotics necessary for doing a repair, or human-rating Starship, either of which is years worth of time.

      Oh yea. Much less memorable than BFS.

  Spitballing here ... could we de-orbit it back to Earth with what propellant remains? Then fix whatever and refill the propellant?

    The sunshield had a complicated unfurling sequence, I very much doubt they could fold it back up while still in orbit.
