The first-ever MCP Night event took place on May 14, 2025, at the Exploratorium in San Francisco, bringing together hundreds of engineers, founders, researchers, and tinkerers to celebrate the Model Context Protocol (MCP). MCP enables large language models to connect with tools, APIs, data, and systems safely, securely, and in a standardized way. The event featured demos from top teams building exciting MCP servers and integrations, showcasing how MCP can be used for various applications such as network and edge automation, browser-based servers, personal assistants, customer contact finding, and workflows. The turnout exceeded expectations, with the main stage reaching capacity, and an overflow demo area was set up to accommodate the large number of attendees. After the talks concluded, the Exploratorium opened up for a museum-wide afterparty, featuring exhibits, music, and drinks, allowing attendees to continue conversations about AI, infrastructure, and auth in a casual setting.
