Over the last several weeks, we’ve built a Sovereign Vault—a forensic system that uses the Model Context Protocol (MCP) to authenticate rare books. We’ve seen the code, survived the logic-checks, and successfully navigated the "Airlock" of local vision and PII redaction.
But as proprietary agent protocols emerge and "black-box" platforms promise to handle everything for you, a question remains: Is MCP still relevant?
Based on our implementation, the answer is a resounding yes. MCP isn't just a "wrapper"; it is the Strategic USB-C for AI Architecture. Here is why.
The Death of the "Glue Code" Tax
Before MCP, every new capability (like a vision model or a database lookup) required custom "glue code" to connect to a specific LLM. In our series, we added The Eye (local vision) and The Librarian (bibliography) without writing a single line of custom integration code for the LLM.
