MCP Security Timeline: From First Launch to OpenAI's Codex Security

By PulseAugur Editorial · [1 sources] ·

The security landscape for Model Context Protocol (MCP) has rapidly evolved, with initial research and tooling emerging shortly after the first remote MCP launches in early 2025. While solutions for exposing private MCP servers existed by Q2 2025 from providers like Cloudflare, ngrok, and Tailscale, a gap persisted for small and medium-sized enterprises lacking dedicated security teams.

IMPACT Provides a historical and security-focused perspective on the evolution of MCP tooling and its implications for developers.
