Can I read these docs as Markdown, and is there an llms.txt?

Yes: add .md to any page's URL or send Accept: text/markdown, and /llms.txt indexes every page and tool. None of it needs a key.

• /llms.txt is the index, and /llms-full.txt holds the whole reference in one file.
• /tools.json gives every tool's name, title, input schema and output schema.
• You'll also find the API catalog, MCP server card, agent skill, agentic resource manifest and the sitemap at /sitemap.xml.
• Markdown responses are served as text/markdown, with an x-markdown-tokens header that estimates their size.
• In a browser that supports navigator.modelContext, pages register these WebMCP tools: search_casafari_mcp_docs, get_casafari_tool_reference, get_casafari_rest_operation, get_casafari_connection_config and open_casafari_docs_page.
