Is Mars in the 1st house good or bad?

Neither on its own. It gives courage and drive, which help when steered and hurt when they spill into conflict. The sign, aspects, and whether Mars is a benefic for your lagna decide how it plays out in a specific chart.

Does Mars in the 1st house cause Mangal dosha?

The first house is one of the positions counted in Mangal dosha, but many classical cancellations can apply, and the rest of the chart matters. A proper reading checks the cancellations rather than declaring dosha from the placement alone.

Mars in the first house

Mars in the first house lends energy, courage, and directness, and asks the person to steer that drive rather than be steered by it.

This is the general classical meaning. Your own reading depends on the sign, aspects, and dasha around the placement, so treat it as a starting point and read your real chart for the specifics.

What this placement generally means

The first house governs the self, body, drive, and outward personality

The first house is the self: the body, the outward personality, and the drive with which you meet the world. Mars is energy, courage, and initiative. Mars in the first house tends to produce a direct, physically energetic person who moves toward what they want rather than waiting for it.

The upside is initiative and courage. People with this placement often start things, defend themselves and others, and carry a visible physical vitality. The work of the placement is temper and patience, because the same fire that drives action can spill into impatience or conflict when it is not steered.

Sign matters a great deal here. Mars in its own sign or exalted reads as disciplined strength, while Mars in a difficult sign can read as friction. Note that Mars in the first house is one of the positions counted in Mangal dosha assessments, and a full reading weighs cancellations and the rest of the chart before drawing any conclusion.

Where it tends to help

Courage, initiative, and a bias toward action
Physical energy and stamina
A protective instinct toward the people you value
Leadership that comes from doing rather than talking

Where it asks for work

Impatience or a short fuse when the energy is not channeled
A tendency toward conflict or haste under pressure
Accident or inflammation themes if Mars is afflicted, which the chart determines
Mangal dosha considerations that a full chart reading must weigh properly

What the classical texts say

Brihat Parashara Hora Shastra reads Mars in the lagna through its dignity and its role as a functional benefic or malefic for the rising sign. Phaladeepika associates Mars in the first with a bold, energetic constitution. Because the first house is also the seat of the body, classical texts weigh Mars aspects and sign carefully before reading it as vitality or as friction.

Why your chart matters: two people can both have Mars in the first house and read very differently, because the sign it occupies, the planets aspecting it, and the dasha they are running are not the same. Ask Acharya reads your actual placement rather than the general case.
