The MTPC educates the public, lobbies state and local government, and encourages political activism.

The MTPC professes to work guided by the following values: "Equal rights and institutional responsibility; working against all forms of oppression; building broad-based participation and community power; developing leaders and building coalitions; drawing strength from diverse experiences and identities; being informed by our history and elders; growing through challenge and critique; being inclusive of those who cannot be fully visible, and accountability to the communities for which we work."

In 2003, MTPC members began advocating for a similar ordinance in Northampton, Massachusetts, which passed in December 2005.

In the summer of 2006, MTPC began developing a campaign for a statewide gender identity/gender expression non-discrimination bill.

Mason J. Dunn is the former executive director of the organization,[3][4] and Maxwell Ng chairs an eight-person steering committee.
