Glossary
of terms

Terms used across this knowledge base, defined plainly.

Application Password

A 24-character token that lets a tool authenticate to your site without using your wp-admin password. You do not create one — the plugin generates and manages its own on activation, and revokes it if you delete the plugin. Scoped, revocable, and bypasses 2FA by core WordPress design.

Cowork

Anthropic’s mode of Claude for longer, multi-step work. WordPress for Cowork works there and in ordinary Claude chat alike.

Custom connector

Claude’s name for a site or service you add yourself under Customize → Connectors. Your WordPress site becomes one: you paste its connection address and sign in to approve it.

Connection address

The address shown on your site’s Cowork page, ending /wp-json/coworkmcp/v1/mcp. It is what you paste into Claude. It never changes, so plugin updates cannot break the connection.

The WordPress for Cowork plugin

The WordPress half of WordPress for Cowork — a plugin you install on your WordPress site (wordpress-for-cowork.zip) that adds the MCP endpoint at /wp-json/coworkmcp/v1/mcp.

License key

Your CW- formatted purchase key (e.g., CW-XXXXXX-XXXXXX-XXXXXX). Lives in your My Account page after purchase. Pasted once into wp-admin → Cowork.

MCP (Model Context Protocol)

The open protocol Claude uses to talk to connectors. WordPress for Cowork’s MCP endpoint at /wp-json/coworkmcp/v1/mcp is what Claude sends requests to.

mu-plugin

“Must-use” plugin. Lives in wp-content/mu-plugins/ and is always active — no separate activation step in wp-admin. The WordPress for Cowork plugin deploys its core endpoint and tool-interceptor as mu-plugins.

Approval

The moment you sign in to your own website and press Allow. Your site then issues Claude its own access and checks it on every request. Your WordPress password is never given to Claude or to us.

REST API

WordPress’s built-in HTTP interface for reading and writing site data. WordPress for Cowork uses it. Lives under /wp-json/.

Seat

One user license. Solo = 1 seat. Agency = 5 seats. Enterprise = per-seat, minimum 6. Sites are unlimited; seats are the constraint.

Run the check

A button on your site’s Cowork page. It tests every step of the connection from your site’s side and names the one that failed, including whether Claude ever reached your site.

Snapshot

A full-site backup taken when you ask Claude to back up your site, and offered before any big change. JSON file stored on your own server in a folder protected by .htaccess.
