The Model Context Protocol (MCP) is a strategic move by Anthropic to solve the fragmentation of AI tool integration. Its defensibility is not based on code complexity (the protocol itself is relatively simple JSON-RPC), but on massive network effects and 'standard-setter' momentum. With over 400 stars on just the documentation repo and high velocity, it is rapidly becoming the de facto standard for connecting LLMs to local and remote data. It mirrors the success of Microsoft's Language Server Protocol (LSP), creating a moat through community adoption: as more 'servers' (data sources like Google Drive, Slack, GitHub) are built, the value for 'clients' (IDEs, AI agents) to support MCP increases exponentially. Frontier risk is 'low' because this is an infrastructure play by a frontier lab (Anthropic) designed to be open, making it an enabler rather than a competitor for them. The primary threat is platform domination from OpenAI or Google if they refuse to adopt it in favor of proprietary alternatives (like ChatGPT Actions), though the open-source community's rapid embrace of MCP makes it hard to ignore. Its displacement is unlikely in the short-to-medium term because once developers build their integration logic against this protocol, the switching costs for the entire ecosystem are high.
