The ProseCaptain MCP is the server through which Claude, Cursor and other AI tools work on your WordPress sites: they write and edit pages and posts, lay out blocks, change menus and footer widgets, add media and set SEO. One address works for every tool:
https://wp-mcp.prosecaptain.com/mcpHow it works
- Connect the site. In the ProseCaptain plugin, click Connect to AI. The plugin creates a separate user
prosecaptain-aiwith the ProseCaptain AI role and hands its application password to ProseCaptain, encrypted. - Issue a token. In the ProseCaptain app, create an MCP token for yourself or a teammate.
- Add the AI tool. Paste the address and the token into Claude Code, Cursor, VS Code or another MCP client. Steps for each are in Connect Claude, Cursor and others.
From then on you can ask, for example: “Add a link to the new Careers page in the squares.pl footer” or “Draft a post about launching a mobile app and set its SEO description”.
Step 1: connect the site
You need the ProseCaptain plugin 2.6 or later and a WordPress administrator account.
- In WordPress, open ProseCaptain → the settings tab and, if you have not yet, click Sign In to connect the site to your workspace.
- In the AI tools (MCP) card, choose whether this is the production or the staging site.
- Accept the terms of AI work on the site and the privacy policy.
- Click Connect to AI.
The site appears in the ProseCaptain app under Settings → AI tools.
Without the plugin: in the app, click Connect a site, sign in to WordPress as a user with the Editor or ProseCaptain AI role and approve access on the WordPress screen. Administrator accounts are refused.
Step 2: issue an MCP token
- In the ProseCaptain app, open Settings → AI tools.
- Click New token, say who it is for (e.g. “Anna, Claude Code”) and accept the terms of AI work.
- Copy the token. It is shown once; only its hash is stored.
Give each person and each tool its own token. You revoke a token in the same place with one click, effective immediately.
Step 3: add the AI tool
Steps for Claude Code, Claude Desktop, Cursor, VS Code, Windsurf and Cline: Connect Claude, Cursor and others.
