Not much to work with here. Likely one of two possible. First is a huntsman, Heteropoda venatoria.
second, a running crab spider, Philodromus genus. (these significantly smaller)

Are they toxic ?
Like nearly all spiders, they are venomous, but neither produce venom that has other than mild effect on humans or pets. Running crab spiders are just that, they will run from animals larger than they are. The huntsman, very fast but people do catch them and tend to ‘play’ with them before releasing outside. They are very reluctant to bite, even if you could provoke one to bite, worst case is like a mild bee sting.

It looks like a Huntsman from the variety of angles of the tarsii. Are the chelacerae that big on H. venatoria?
Chelecera are about nominal for the size of spider. Here is a gal holding her egg sac with fangs and pedipalps.
