In 2002, MPC founded the Bantay Ceasefire as an independent grassroots ceasefire monitoring mechanism which since then has grown to over a thousand well-trained and highly committed women and men volunteers. In 2010, upon the invitation of the peace panels, MPC has formally deployed an all-women contingent in the Civilian Protection Component of the International Monitoring Team.

Over the last 10 years, the MPC has been in the forefront of Peace advocacy work and has championed the peace talks between the Philippine Government and Moro Islamic Liberation Front with the end in view of putting a final closure to the armed conflict in Mindanao through a negotiated political settlement. MPC supports the right to self-determination of the indigenous and Bangsamoro peoples and builds the much needed national and international solidarity in support of their struggles.
