v0.15.1 — Built for ChatGPT Work and Codex Site tools

WebMCP Adapter 0.15.1 makes the supported product boundary explicit: this plugin provides frontend WordPress Site tools for ChatGPT Work and Codex in the ChatGPT desktop app's built-in browser.

What changed

• The plugin description, settings, activity UI, README, architecture, development guide, WebMCP reference, and bundled agent instructions now use the same ChatGPT Work and Codex positioning.
• System Chrome, Playwright, raw CDP, and WordPress Playground are documented as deterministic page-side regression harnesses, not product clients.
• The stale backend-catalog browser-agent article has been replaced with the current frontend-only workflow.
• A detailed Site tools guide and a speech-friendly PDF edition are now included.

There is no tool-contract or migration change from 0.15.0. The inventory remains 7 read tools by default, 15 with unsaved editor writes enabled, and 16 with the separately gated save/publish tool enabled.

This remains an experimental plugin for local or throwaway WordPress sites. WordPress 7.0+ and PHP 8.1+ are required.

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-post persistence 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.

v0.14.0

Fixed

• Server abilities now load on sites running the current Gutenberg plugin. The adapter relied on @wordpress/core-abilities seeding the client store as a side effect of import. The newer Gutenberg build changed that contract to an explicit initialize() call, so on those sites the ~250 server-registered abilities (the abilities-catalog, WooCommerce, Jetpack Forms, comments, Akismet, core) silently failed to appear — only the adapter's own in-editor webmcp/* tools showed. The adapter now calls initialize() when present (backward-compatible with the seed-on-import core build). Verified on a live site: a clean wp-admin load registers all tools.

Full diff: v0.13.0...v0.14.0

v0.13.0

WebMCP Adapter 0.13.0.

Reads each registered WordPress ability from the client store and registers it as a WebMCP tool on wp-admin. Reads, writes, destructive, and dangerous tiers with write-gating, a trusted-event confirmation modal, and a server-side activity log/review screen. Front-end Gutenberg editor abilities drive the live post and Site Editor.
