How close do you need to be to feel the Mercury MC line?

Astrocartography lines are typically considered active within about 70–100 miles (110–160 km) on either side. The closer you are to the Mercury MC line, the stronger the communication effect; past roughly 200 miles the influence fades into background. Parans — where this line crosses another planetary line — can extend the effect as a narrow latitude band across the globe.

Is the Mercury MC line good or bad?

No astrocartography line is objectively "good" or "bad" — each amplifies a specific energy. The Mercury MC line emphasizes communication, learning, commerce, short travel through career, reputation, public image, life direction. Whether that's welcome depends on what you want from a location: the same line can feel supportive if the theme matches your goals, and challenging if it doesn't.
