Every page on this site is available as raw Markdown (append .md to the URL) and through the read-only gmc-docs MCP endpoint at /mcp. That endpoint serves product documentation only. Market-data operations live on the separate GMC MCP, described in MCP servers. Discovery files: /llms.txt, /llms-full.txt, and /agent-readability.json.
