The easiest way: wp2ai is listed in Claude's official connectors directory as wp2ai for WordPress.
Manual setup (custom connector): in Settings, then Connectors, choose "Add custom connector", enter a name (for example "wp2ai for WordPress") and the address https://mcp.wp2ai.io/mcp, then click Continue. Authentication starts right away.
If you added wp2ai before October 2026 as a custom connector, it keeps working. If Claude says a tool cannot be found, disconnect and reconnect the connector so Claude reloads the current list of tools.
