Cowboy MCP 1.5.3: Connection Doctor tells you why your agent can't connect

If your AI agent can't reach your WordPress site, Cowboy MCP 1.5.3 tells you exactly why. The new Connection Doctor runs a one-click self-test from the Connection tab and names the likely culprit, instead of leaving you to guess.

What this means for you

Connection problems are the most frustrating part of setting up any MCP server: the agent just says "can't connect," and you're left wondering whether it's your host, a security plugin, or a typo. Connection Doctor turns that dead end into a checklist. It tests the four things that actually break connections — HTTPS, whether your site is publicly reachable, whether the REST API is available, and whether OAuth discovery works — and reports what passed and what didn't.

When something fails, it doesn't just say "error." It names the likely blocker — Cloudflare, ModSecurity, Basic Auth, or a caching plugin — so you know where to look. And it hands you a copy-pasteable report you can drop straight into a support thread instead of describing the problem from memory.

You can run it three ways: from the Connection tab in wp-admin, as the wp_connection_doctor tool so your agent can diagnose itself, or from the command line.
