v0.15.0 — Frontend-only Codex Site tools
WebMCP Adapter 0.15.0 makes the live WordPress editor work as a focused set of Codex Site tools in the ChatGPT desktop app's built-in browser.
Important scope change
The adapter no longer loads or exposes WordPress server/backend abilities. Sites that relied on the former backend catalog must use the REST API or a server-side MCP adapter for those operations. No companion abilities-catalog plugin is required for the frontend editor tools.
What is available
- 7 read tools are available after the page tool inventory settles.
- Enabling Write tools adds 8 reversible, unsaved editor tools, for 15 total.
- Also enabling Destructive tools adds the confirmed
save-postpersistence tool, for 16 total. - Post Editor and Site Editor tools cover navigation, editor context, block discovery and editing, patterns, templates, undo, and save/publish.
Codex and browser compatibility
- Registers imperative tools in the top-level
document.modelContext, matching Codex Site tools behavior. - Rediscovery works after navigation and reload.
- Transitional Chrome input behavior is detected with a harmless read-only probe before requested tools execute.
- Unanswered save/publish confirmation dialogs expire safely after 60 seconds, and expiry is recorded separately from a user decline.
This remains an experimental plugin for local or throwaway WordPress sites. WordPress 7.0+ and PHP 8.1+ are required.
