MCP: Rapid Adoption, Growing Pains, and a Call to Action

This article is a response to a critique of the MCP protocol, a standard for calling tools from LLMs. The author argues that the critique focuses too much on transport mechanisms (e.g., WebSockets) while overlooking MCP's core value: OAuth 2.0 authentication and enabling LLMs to interact with the real world. While acknowledging issues like tool security and multi-tenant server compatibility, the author emphasizes MCP's rapid adoption and the community's efforts to address these challenges. The author concludes with a call to action for developers to participate in shaping MCP's secure and reliable future.
