The Seoul Inflection Point More than 21,000 internet-facing MCP server instances are currently exposed, with nearly 92% of audited production servers lacking basic OAuth authentication. This data, surfacing alongside a growing catalog of critical CVEs and the formalization of the OWASP MCP Top 10, has transformed the Model Context Protocol (MCP) Dev Summit in Seoul this August 13–14, 2026, from a routine industry check-in into a high-stakes confrontation. For the first time, protocol designers and the security community are meeting in person to address a vulnerability landscape that has shifte
