Cowboy MCP 1.6.1: SEO by chat, plus users, menus, and a safer media library

By Andrew Ivanov · Last updated 2026-07-26

Cowboy MCP 1.6.1 rounds out the core toolset — your agent can now manage users, navigation menus, and the media library — and adds the headline feature: real SEO work on Yoast SEO or Rank Math sites through one unified set of tools. The toolset grows from 137 to 153, and everything new is journaled and undoable like the rest of the plugin.

What this means for you

"Fix my SEO" is one of the most common jobs people hand an AI agent, and until now Cowboy MCP could only tell the agent which SEO plugin was installed. This release gives it hands: it can read and write every post's SEO meta and audit the whole site for problems — using the same tools whether you run Yoast SEO or Rank Math.

What's new

SEO meta management (Yoast SEO & Rank Math). Read and update a post's SEO title, meta description, focus keyword, noindex/nofollow, canonical URL, and Facebook/X social overrides. One vocabulary regardless of which SEO plugin you run — the adapter handles the storage differences, and template variables like %%category%% pass through intact.
Site-wide SEO audits. Scan posts and pages for missing or badly sized meta descriptions, missing focus keywords, over-long titles, and published posts accidentally left noindexed — paginated so it works on big sites.
User management with hard rails. List, create, update, and delete users, including role changes. Granting an administrator-level role, setting a password, or changing a privileged user's email requires Power mode — and an agent can never change its own credentials or remove the last administrator.
Navigation menus. Create and rename classic menus, assign theme locations, and set the whole menu tree in one call.
A safer media library. List attachments — including a missing-alt-text filter, handy for accessibility and image-SEO passes — edit titles, captions, and alt text, and delete attachments knowing the files are moved aside rather than destroyed, so the deletion can be undone from the Activity tab.

SEO changes are journaled like everything else, and on Yoast sites the indexable cache refreshes automatically, so edits show up on the live site immediately.
