Your copilot can use this site directly.
This site speaks to AI agents natively: a machine-readable site map at /llms.txt, clean markdown mirrors of every plan and service, and an MCP endpoint at o365hq.com/mcp with tools for catalog search, live CSP pricing, core-licensing math, and human-confirmed quote requests.
