Beschreibung
RealMCP lets your AI assistant work on your WordPress site. Ask it to build a landing page with your theme’s blocks and colors, draft a blog post with its categories and tags, find and update existing content, or go through the comments waiting for review. New pages and posts start as drafts unless you ask the assistant to publish them.
It works with Claude (web, desktop and mobile), Claude Code, Codex, ChatGPT and other assistants that support the Model Context Protocol (MCP). They connect directly to your site: you paste the server URL (https://example.com/wp-json/ballesdev/mcp) in the assistant, log in to WordPress and approve. Nothing to install on your computer, and no account on another service. The AI acts as the WordPress user who approved it, with that user’s permissions.
Tools:
- site-context: theme, page templates and design presets (colors, font sizes, spacing, layout widths).
- list-pages / get-page / save-page: find, read, create and update pages as block markup.
- list-posts / get-post / save-post: the same for blog posts, with categories, tags, featured image and scheduling.
- list-terms / save-term: categories and tags.
- search-content: search posts and pages at once, drafts included.
- list-comments: comments by status, without the commenter’s email or IP.
- moderate-comment / reply-comment: approve, hold, spam, trash or reply. Off by default.
- list-blocks / list-patterns / list-media: registered blocks, patterns and images.
- site-health: WordPress, PHP and database versions, the available updates and the Site Health status, which it can also check on demand. Read only.
New pages and posts are drafts unless the AI sets another status, and updates are rejected if the content changed since it was read. Each tool asks for the capability it needs (pages need edit_pages, comments need moderate_comments), and the AI only sees the tools its user can use.
In the RealMCP menu, every user who can use the server finds the Connect tab: the server URL, the steps for each assistant, their connections with a button to disconnect each one, connection tokens for assistants without OAuth, and a check of what the site needs. Administrators can also:
- turn each tool on or off. A disabled tool disappears from the list AI clients see, and calls to it are rejected. Tools that act on behalf of the site, such as replying to comments, start disabled;
- review the activity log: every tool call, with the user, the connection and client used, the item it affected, the result and how long it took. Entries are kept for 30 days by default.
The tools are registered with the WordPress Abilities API, so sites running the MCP Adapter plugin can use them too.

External services
RealMCP doesn’t send your content anywhere. It contacts other sites only in these two cases:
- The assistant’s public description. When you approve an assistant in the RealMCP approval screen, your site downloads that assistant’s client metadata document (its name and the addresses it may return to) from the address the assistant gives. The request carries no data from your site or about you; the assistant’s server sees your site’s IP address, like any web request. The document is cached for up to a day. An assistant that isn’t listed here but supports the same standard is contacted at the address it declares, shown on the approval screen before you approve. The assistants documented here publish it at:
- Claude and Claude Code, by Anthropic:
https://claude.ai/oauth/mcp-oauth-client-metadataandhttps://claude.ai/oauth/claude-code-client-metadata. Terms, privacy policy. - Codex and ChatGPT, by OpenAI:
https://chatgpt.com/oauth/codex/client.jsonandhttps://chatgpt.com/oauth/client.json. Terms, privacy policy.
- Claude and Claude Code, by Anthropic:
- WordPress.org. Only when you ask the site-health tool to check the site now: it runs WordPress’s own Site Health tests, which check that your site can reach WordPress.org, as in their weekly run. Privacy policy.
Your AI assistant requests content from your site through RealMCP; what happens to that content afterwards depends on the assistant you use and its provider’s terms.

Installation
- Install and activate the plugin. Your site needs HTTPS and a permalink structure other than Plain (Settings > Permalinks).
- Log in as the user the AI will act as. The page tools need a user who can edit pages, such as an Editor or an Administrator.
- Go to RealMCP > Connect and follow the steps for your assistant. In Claude, the „Add to Claude“ button opens the connector with your site already filled in.
The first time, the assistant opens your site’s login page and asks you to approve it. Each approved assistant appears in your profile as an Application Password named „RealMCP: …“: delete it, or click Disconnect in RealMCP > Connect, to revoke access.
FAQ
-
How do I connect Claude?
-
In Claude (claude.ai, Claude Desktop or the mobile app), go to Settings > Connectors > Add custom connector, paste your server URL (
https://example.com/wp-json/ballesdev/mcp) and keep the sign-in options Claude detects. Then log in to your site and approve. Or click „Add to Claude“ in RealMCP > Connect. Claude connects from Anthropic’s servers, so your site must be reachable from the internet. -
How do I connect Claude Code?
-
Run:
claude mcp add --transport http my-site https://example.com/wp-json/ballesdev/mcpThen type
/mcpin Claude Code, choose the server and sign in. -
How do I connect Codex?
-
Run:
codex mcp add my-site --url https://example.com/wp-json/ballesdev/mcp codex mcp login my-siteThe Codex CLI, the IDE extension and the app share this configuration.
-
How do I connect ChatGPT?
-
In ChatGPT on the web, open the plugins page, choose to add a custom MCP server and paste your server URL. Custom servers depend on your ChatGPT plan.
-
How do I connect OpenCode, VS Code or Cursor?
-
Open RealMCP > Connect and choose the „Other assistants“ tab. For OpenCode, run
opencode mcp add my-site --url https://example.com/wp-json/ballesdev/mcpand thenopencode mcp auth my-site. For VS Code and Cursor, the buttons open the editor with the server ready to add. -
My assistant can’t sign in with OAuth
-
Create a connection token in RealMCP > Connect („Connection token“) and send it in the
Authorizationheader asBearer rmcp_mt_…. In Claude, add the custom connector with „No sign-in“ and that header. The token is shown only once. You choose when it expires (90 days by default), and you can disconnect it at any time. -
The assistant can’t find how to sign in
-
Click „Check now“ in RealMCP > Connect. If OAuth discovery says Blocked, your web server doesn’t pass
/.well-known/addresses to WordPress (the nginx configuration suggested by WordPress blocks every path that starts with a dot). Ask your host to allow/.well-known/oauth-authorization-server, or use a connection token. The server URL must not redirect to another address, such as fromexample.comtowww.example.com: use the final one. -
I approved, but Claude says the site refused its request
-
If your site is behind Cloudflare or a firewall that blocks AI bots, it may let the sign-in through and block Claude’s requests afterwards. Allow Anthropic’s address range 160.79.104.0/21, or the paths
/wp-json/ballesdev/and/.well-known/oauth-. -
The assistant connects, but every request fails with a 401 error
-
Some servers drop the
Authorizationheader before it reaches WordPress: „Check now“ in RealMCP > Connect tells you if yours does. On Apache, re-saving Settings > Permalinks restores the rule that passes it through. On other servers, ask your host. Also check that the Application Passwords section appears in your profile: RealMCP stores each connection as one, and some security plugins and hosts turn them off. -
What can the AI do on my site?
-
Only what the connected user can do. It reads pages, posts, blocks, patterns, media, comments and design settings; it creates, edits and, if the user is allowed to, publishes pages and posts; and, if you turn those tools on, it moderates and replies to comments. New content is a draft unless the AI sets another status. What the AI saves goes through WordPress’s HTML filter, even for administrators: scripts, iframes and event-handler attributes are removed. To limit it further, turn tools off in RealMCP > Tools: turning off every Write tool allows reading only. Comment text is written by visitors, so the AI is told to treat it as data, never as instructions. To revoke access, click Disconnect in RealMCP > Connect, or delete the connection’s Application Password from the user’s profile.
-
What does the activity log record?
-
Each tool call made through the plugin’s MCP endpoint: the date, the WordPress user, the name of the connection used, the client (its User-Agent), the tool, the item it affected, the result and how long it took. It never records content. Entries older than the retention you set (30 days by default) are deleted once a day, and a user’s entries are deleted with the user. They are also included in WordPress’s personal data export and erasure tools. Calls that reach the same tools through other routes, such as the MCP Adapter plugin, are not logged.
-
Does the plugin send my data anywhere?
-
The plugin only contacts other sites in two cases, and never sends your content:
- When you approve an assistant, your site reads that assistant’s public description (its name and the addresses it returns to), published by its maker at the address the assistant gives, for example
https://claude.ai/oauth/claude-code-client-metadata. The request carries no data from your site, and the description is cached for up to a day. - When you ask site-health to check the site now, it runs WordPress’s own Site Health tests, which, as in their weekly run, check that your site can reach WordPress.org.
The activity log stays in your site’s database. Your AI assistant requests content from your site; what happens to that content depends on the assistant you use.
- When you approve an assistant, your site reads that assistant’s public description (its name and the addresses it returns to), published by its maker at the address the assistant gives, for example
