I was the one writing the MCP layer — designing the tools, mapping them to the existing API endpoints, and making the backend legible to an AI. The backend was live. The APIs were working. A frontend client was consuming them without complaints. I was working under strict constraints — no changes to the backend, no changes to the existing client.
