Quaker Houghton MCP Server
A remote Model Context Protocol server served from home.quakerhoughton.com by the WordPress MCP Adapter plugin, discovered through the RFC 8414 and RFC 9728 documents the host publishes under /.well-known/. It is OAuth 2.1 gated (authorization-code + PKCE, single scope `mcp`, public clients via client-ID metadata documents); anonymous tools/list returns 401 mcp_unauthorized, so the tool inventory is unknown. It fronts the corporate website's content estate, not any fluid-management product.
