Install WordPress MCP Server in Claude Code

What you need first

• Claude Code, installed.
• Node.js, which gives the npx command the server starts with.
• Your own values for YOUR_LOCAL_USERNAME,YOUR_WP_DB_HOST,YOUR_WP_DB_NAME,YOUR_WP_DB_USER,YOUR_WP_DB_PASSWORD.

Steps

1. Run this in a terminal, in the project folder. It adds the server for you in that project; put --scope user after claude mcp add to have it in every project.

claude mcp add --env LOCAL_USERNAME=YOUR_LOCAL_USERNAME --env WP_DB_HOST=YOUR_WP_DB_HOST --env WP_DB_NAME=YOUR_WP_DB_NAME --env WP_DB_USER=YOUR_WP_DB_USER --env WP_DB_PASSWORD=YOUR_WP_DB_PASSWORD --transport stdio wp-mcp -- npx -y @rnaga/[email protected] local start

2. Replace YOUR_LOCAL_USERNAME,YOUR_WP_DB_HOST,YOUR_WP_DB_NAME,YOUR_WP_DB_USER,YOUR_WP_DB_PASSWORD with your own values.
3. Start Claude Code and type /mcp: the server is listed with its state.

Check it worked

Ask Claude Code: List the tools of wp-mcp.

If it does not start

spawn npx ENOENT

Node.js is not on the PATH that Claude Code sees. Install it, or write the full path of npx in the config.

The server starts, but its tools fail

A YOUR_… placeholder is still in the config, or its value is wrong.
