I built a WordPress.com Codex skill (and gave it a publish button)

By willmot on February 6, 2026 — 1 min read

I’ve been doing more with OpenAI Codex recently and wanted a clean way to connect to me WordPress.com blog.

Codex adapted the exising Claude connector into a Codex skill and I added REST API support for publishing as WordPress.com MCE is currently read only.

What this skill does

  • Connects WordPress.com with OAuth 2.1 + PKCE
  • Calls the official MCP endpoint
  • Falls back to REST for post publishing as wordpress.com MCP is readonly

What’s in the repo

  • SKILL.md for setup and runbook guidance
  • references/endpoints.md for OAuth/MCP/REST endpoints
  • scripts/publish_post.py for publishing via REST API

If you want to try it, and you hit any rough edges, send me a note.
