Mintlify launched mcpt.com, an MCP server registry, shortly after their MCP generator gained significant popularity, but opted to shut it down just five days later despite attracting 3,000 visitors. The decision was influenced by three main factors: the considerable operational resources required to maintain a marketplace, the potential diversion of focus from their core developer tools, and an acknowledgment that marketplace development wasn't aligned with their strengths. The experience underscored the importance of staying focused on their core competencies during periods of rapid growth. By sharing this story, Mintlify aims to highlight the value of discussing the challenges and decisions involved in product development, particularly those that occur in the midst of growth and experimentation.
