Connect Cursor to your own WordPress site over the Model Context Protocol. Cursor talks to your site directly — there is no relay in between, no account to create, and your credentials never leave your machine. Setup takes about a minute once MCP Manager is installed.

Before you start
You need AcrossAI MCP Manager installed and active on the WordPress site you want Cursor to reach, plus an administrator account on that site. If you have not installed it yet, follow the Get Started guide first — it takes about a minute, and the MCP server ships bundled with the plugin.
You also need Node.js available on the machine running Cursor, because the connection runs through an npx bridge. Nothing is installed permanently — npx fetches the bridge on demand.
How to connect Cursor to WordPress
Step 1
Open Quick Connect and choose Cursor
In wp-admin go to AcrossAI → MCP, open the server you want to expose, and start Quick Connect. Pick Cursor from the client list. Everything below is generated for you with your real site URL and username already filled in — the snippets here are only so you know what to expect.
Step 2
Generate an Application Password
Click Generate password in the wizard. This creates a standard WordPress Application Password — not your login password — scoped to this connection and revocable at any time from your user profile.
The password is shown once, at creation. Copy it whole, including the spaces — WordPress accepts them. If you lose it, generate a new one rather than trying to recover it.
Step 3
Paste the config into ~/.cursor/mcp.json
Copy the JSON from the wizard, open ~/.cursor/mcp.json — create it if it does not exist — and paste the entry under the mcpServers key. If you already have other MCP servers configured, add this one alongside them rather than replacing the file.
The generated config looks like this, with your own values in place of the placeholders:
{
"mcpServers": {
"your-site-mcp-adapter-default-server": {
"command": "npx",
"args": ["-y", "@automattic/mcp-wordpress-remote@latest"],
"env": {
"WP_API_URL": "https://example.com/wp-json/acrossai/mcp",
"WP_API_USERNAME": "your-wp-username",
"WP_API_PASSWORD": "xxxx xxxx xxxx xxxx xxxx xxxx"
}
}
}
}Step 4
Restart Cursor and check the tools
Restart Cursor so it reads the new configuration. Your site should appear as an MCP server, and the toolsets it exposes become available in chat. Ask something harmless to confirm it is live — “Which plugins on this site need updating?” is a good first test.
Want the one-click Cursor connector?
AcrossAI Pro turns this setup into a managed one-click connector, with the controls a live site needs:
- See every connected client and revoke it in one click
- Require admin approval before anyone connects
- Gate tools by membership level across ten providers
What Cursor can do once it is connected
With Abilities Manager installed alongside it, Cursor reaches 350+ abilities across 14 toolsets — rising past 800 once it detects the plugins you already run. From inside your editor, without switching to a browser tab, it can:
- Read and edit content — posts, pages and any custom post type with their meta and revisions, and surgically edit a page’s block tree without rewriting the page.
- Debug a broken site — read the debug log with secrets redacted, check Site Health, list recent fatal errors and un-pause what WordPress auto-disabled.
- Inspect the database — schema and table sizes, index health, bloated autoloaded options, or
EXPLAINon a slow query. - Manage plugins, themes and core — search WordPress.org, install, update, roll back, and verify files against official checksums.
- Work with files — inside an allowlist you define, with a dangerous-extension blocklist and optional pre-image backups of everything it touches.
- Reach the plugins you already run — WooCommerce, Elementor, ACF, Rank Math, Yoast, WPCode and more, each registering only when that plugin is active.
Every ability runs WordPress’s own capability check for the calling user, so Cursor can never do anything your account could not already do. See the full platform overview for the complete catalogue.
Frequently asked questions
Is connecting Cursor to WordPress free?
Yes. AcrossAI MCP Manager and Abilities Manager are both free and GPL on WordPress.org, and there is no AcrossAI account to create. You use the Cursor subscription you already have — AcrossAI never charges for AI inference, because none of it runs here.
Does my site data pass through AcrossAI servers?
No. Cursor connects straight to your own domain and every request terminates at your /wp-json/ route. There is no relay, no gateway and no telemetry. Whatever Cursor reads is still processed by your AI provider, so treat it as you would any other prompt.
Does it work on any WordPress host?
Yes, provided you can reach wp-admin. Shared hosting, VPS and managed WordPress all work, because everything runs inside your own install. MCP Manager needs WordPress 7.0 or later and PHP 8.1 or later.
Can Cursor break my site?
Every ability runs WordPress’s own capability check for the calling user, so Cursor can never exceed what your account can already do. Higher-risk operations refuse to run without an explicit confirmation flag, file access is confined to an allowlist you define, search-and-replace is a dry run by default, and any ability can be disallowed site-wide.
How do I disconnect Cursor again?
Revoke the Application Password from your WordPress user profile, or remove the entry from ~/.cursor/mcp.json. Access is re-checked on every request, so revoking takes effect immediately even if the config is still on the machine.
Troubleshooting
Cursor does not list the server at all
Cursor reads ~/.cursor/mcp.json at startup, so a full restart is required — reloading the window is not always enough. Check the file is valid JSON: a trailing comma or a missing brace makes Cursor skip the whole file silently. Confirm your entry sits under mcpServers and not at the root.
The server appears but has no tools
That is the connection working and the catalogue being empty. Either Abilities Manager is not installed — MCP Manager will serve an empty catalogue quite happily — or the abilities exist but are not exposed to this particular server. Open AcrossAI → MCP, select the server, and check its Tools and Abilities tabs. After changing what a server exposes, restart Cursor: MCP clients receive their tool list once, at connection time.
Authentication fails
Application Passwords are shown once and are not your login password. Generate a fresh one from Quick Connect rather than retyping an old one, and copy it complete with spaces. If the request is being refused rather than failing, check the server’s access rules — a new server requires manage_options until you add a rule, and the gate fails closed.
It worked yesterday and stopped today
Access is re-checked on every request, not just at setup. A change to your role, capability or membership takes effect immediately, and a saved config does not keep working. Revoking the Application Password has the same effect.
npx is not found
The bridge runs through npx, which ships with Node.js. Install Node.js on the machine running Cursor and restart it. If Node is installed through a version manager, Cursor may not inherit your shell’s PATH — in that case point command at the absolute path to npx.
Connect a different AI client
The same server works with every MCP client — only the config file and top-level key change. See the guides for Claude Desktop, Claude Code, VS Code, GitHub Copilot, Windsurf, Zed, Codex and every other client.
