Ah. I see. I misread "remotely from agenda" as "not in the agenda".

You can jump to the current entry in a number of ways. There is the
function org-agenda-goto. Within the agenda, you can also get the
markers for the current entry with:

(org-get-at-bol 'org-marker)
(org-get-at-bol 'org-hd-marker)

You can use these markers (usually with save-excursion or
save-window-excursion) to jump to the function and alter it. The code of
org-agenda-todo provides a nice example of this.

It would be nice if this functionality were abstracted a bit in
org-agenda.el. Right now, each of the org-agenda editing commands
(org-agenda-todo, org-agenda-set-tags, org-agenda-priority,
org-agenda-add-note, etc.) reimplements the same behavior.

Best,
