MCP – Model Context Protocol, recently (March 2025) announced by Anthropic, is a standard model for how applications and services can be discovered and interacted with in a universal way. MCP leverages language models to summarize the rich output of these services and can present information in a human-readable form. MCP is analogous to USB-C, which is a standard for connecting devices and operating systems, connecting agents to software applications and services. Until now, every agentic developer has had to write their own custom plumbing, glue code, etc., to do this. Without a standard like MCP, building real-world agentic workflows is essentially impossible.
