ItchWPMCP

Local MCP server for Codex/Claude to query and edit WordPress content through the WordPress REST API.

It can be used with any WordPress site that has the REST API enabled and supports Application Password authentication.

Setup

1. Create a WordPress application password: WordPress Admin -> Users -> Profile -> Application Passwords

2. Copy .env.example to .env and fill in:

   WP_BASE_URL=https://your-wordpress-site.example
   WP_USERNAME=your-wordpress-username
   WP_APP_PASSWORD=xxxx xxxx xxxx xxxx xxxx xxxx
   WP_ALLOW_PRODUCTION_WRITES=false

3. Install dependencies:

   npm install

4. Run the server:

   npm start

   If Node cannot verify your site's certificate chain, set NODE_OPTIONS=--use-system-ca in your MCP client environment.

Write tools are enabled on staging URLs. If WP_BASE_URL is changed to production, writes are blocked unless WP_ALLOW_PRODUCTION_WRITES=true is set in .env.

Elementor Meta Tools

Use wordpress_update_elementor_meta when you need to save Elementor layout data through WordPress REST. Pass elementorData as either a JSON string or a JSON object/array; the tool stores it as _elementor_data.

Example:

{
  "id": 123,
  "postType": "page",
  "elementorEditMode": "builder",
  "elementorTemplateType": "wp-page",
  "elementorVersion": "3.30.0",
  "wpPageTemplate": "elementor_canvas",
  "elementorData": []
}

The available Elementor REST endpoints depend on the target WordPress site and installed Elementor plugins. Use wordpress_list_elementor_routes to inspect what the configured site exposes, then use wordpress_elementor_rest_request for site-specific Elementor endpoints.

If a meta key does not update through wordpress_update_post_meta, the target WordPress site has not registered that key for REST writes. In that case, add a small WordPress helper plugin or mu-plugin to register the specific meta keys with show_in_rest.

Use Another WordPress Site

Create an Application Password in that WordPress site's admin, then update .env:

WP_BASE_URL=https://another-wordpress-site.example
WP_USERNAME=your-wordpress-username
WP_APP_PASSWORD=xxxx xxxx xxxx xxxx xxxx xxxx
WP_ALLOW_PRODUCTION_WRITES=false

Keep WP_ALLOW_PRODUCTION_WRITES=false until you intentionally want write tools enabled on a production URL.

Port It For Another Person

1. Copy this ItchWPMCP folder to their machine or publish it as a private/public repo.

2. Run npm install inside the folder.

3. Create a .env file from .env.example.

4. In their WordPress admin, create an Application Password: Users -> Profile -> Application Passwords

5. Put their site URL, username, and app password in .env.

6. Register the MCP server in their MCP client.

Do not commit .env files. Application Passwords should stay local to each user/site.

Codex Config

Add this to ~/.codex/config.toml:

[mcp_servers.itch_wp_mcp]
command = "node"
args = ["<absolute-path-to-ItchWPMCP>/src/server.js"]
enabled = true
startup_timeout_sec = 20
tool_timeout_sec = 60

[mcp_servers.itch_wp_mcp.env]
WP_BASE_URL = "https://your-wordpress-site.example"
WP_USERNAME = "your-wordpress-username"
WP_APP_PASSWORD = "xxxx xxxx xxxx xxxx xxxx xxxx"
WP_ALLOW_PRODUCTION_WRITES = "false"
NODE_OPTIONS = "--use-system-ca"

If your MCP client cannot find node, set command to the absolute path of your Node executable. For example:

command = "<absolute-path-to-node>"

Claude Desktop Config

Add this to Claude Desktop's claude_desktop_config.json under mcpServers:

{
  "mcpServers": {
    "itch_wp_mcp": {
      "command": "node",
      "args": [
        "<absolute-path-to-ItchWPMCP>/src/server.js"
      ],
      "env": {
        "WP_BASE_URL": "https://your-wordpress-site.example",
        "WP_USERNAME": "your-wordpress-username",
        "WP_APP_PASSWORD": "xxxx xxxx xxxx xxxx xxxx xxxx",
        "WP_ALLOW_PRODUCTION_WRITES": "false",
        "NODE_OPTIONS": "--use-system-ca"
      }
    }
  }
}

Restart Claude Desktop after changing the config.

Multi-Site Setup

You do not need a separate copy of ItchWPMCP for every WordPress website. Keep one codebase and register multiple MCP servers, each with different environment variables.

Codex Multi-Site Example

[mcp_servers.wp_site_staging]
command = "node"
args = ["<absolute-path-to-ItchWPMCP>/src/server.js"]
enabled = true
startup_timeout_sec = 20
tool_timeout_sec = 60

[mcp_servers.wp_site_staging.env]
WP_BASE_URL = "https://staging.example.com"
WP_USERNAME = "site-admin"
WP_APP_PASSWORD = "xxxx xxxx xxxx xxxx xxxx xxxx"
WP_ALLOW_PRODUCTION_WRITES = "false"
NODE_OPTIONS = "--use-system-ca"

[mcp_servers.wp_client_site]
command = "node"
args = ["<absolute-path-to-ItchWPMCP>/src/server.js"]
enabled = true
startup_timeout_sec = 20
tool_timeout_sec = 60

[mcp_servers.wp_client_site.env]
WP_BASE_URL = "https://client-site.example"
WP_USERNAME = "client-admin"
WP_APP_PASSWORD = "xxxx xxxx xxxx xxxx xxxx xxxx"
WP_ALLOW_PRODUCTION_WRITES = "false"
NODE_OPTIONS = "--use-system-ca"

Claude Multi-Site Example

{
  "mcpServers": {
    "wp_site_staging": {
      "command": "node",
      "args": ["<absolute-path-to-ItchWPMCP>/src/server.js"],
      "env": {
        "WP_BASE_URL": "https://staging.example.com",
        "WP_USERNAME": "site-admin",
        "WP_APP_PASSWORD": "xxxx xxxx xxxx xxxx xxxx xxxx",
        "WP_ALLOW_PRODUCTION_WRITES": "false",
        "NODE_OPTIONS": "--use-system-ca"
      }
    },
    "wp_client_site": {
      "command": "node",
      "args": ["<absolute-path-to-ItchWPMCP>/src/server.js"],
      "env": {
        "WP_BASE_URL": "https://client-site.example",
        "WP_USERNAME": "client-admin",
        "WP_APP_PASSWORD": "xxxx xxxx xxxx xxxx xxxx xxxx",
        "WP_ALLOW_PRODUCTION_WRITES": "false",
        "NODE_OPTIONS": "--use-system-ca"
      }
    }
  }
}

The .env file is now only a local fallback. Per-site MCP environment variables take precedence when provided by Codex or Claude.

Safety Model

• New pages/posts default to draft.

• Destructive tools require confirmDelete=true.

• Non-staging writes are blocked unless WP_ALLOW_PRODUCTION_WRITES=true.

• wordpress_rest_request only allows paths under /wp-json/.
