Tronox MCP Server (WordPress MCP Adapter) is published by [Tronox Holdings](https://apis.io/providers/tronox-holdings/) on the [APIs.io](https://apis.io/) network. Tagged areas include MCP, Agents, and WordPress. The published artifact set on APIs.io includes authentication docs.

An authenticated Model Context Protocol (MCP) endpoint served from Tronox's own corporate WordPress host, found by probe on 2026-09-17 rather than by documentation. Anonymous discovery works end to end: the 401 carries a WWW-Authenticate resource_metadata pointer, the site publishes RFC 9728 protected-resource metadata and RFC 8414 authorization-server metadata advertising an authorization_code + PKCE (S256) flow with a single "mcp" scope, and the WordPress REST index confirms the mcp and wp-abilities/v1 namespaces. tools/list itself returns 401 mcp_unauthorized without a bearer token, so the live tool schemas could not be introspected. This is the platform-authored content surface of the marketing site, not a Tronox product, order or supply-chain API - Tronox publishes none. The hosts the previous record carried, api.tronox.com and developer.tronox.com, do not exist (NXDOMAIN).
