When Anthropic released the Model Context Protocol, it promised a new era of agentic AI—but left developers wanting better testing tools. Marcelo Jimenez Rocabado, a 24-year-old CTO, forked Anthropic’s MCP Inspector to build MCPJam, a faster, more collaborative open-source alternative. Backed by Open Core Ventures and a growing developer community, MCPJam is now shaping the standard for AI server testing, proving that agility and open collaboration can outpace even the biggest players.
