wordpress-mcp

Lightweight WordPress MCP server for site management. 85 tools with token-optimized responses — REST API responses automatically slimmed from kilobytes to essentials.

v2.0: Now includes extended tools for the mcp-endpoints plugin — install plugins/themes from WordPress.org, database management, full widget/menu control, and more.

Why This Server?

WordPress REST API returns extremely verbose JSON (~5-10KB per post). This server strips it down:

Response	Before	After	Reduction
wp_list_posts (10 posts)	~50KB	~2KB	96%
wp_get_post	~5KB	~200 bytes	96%
wp_list_plugins	~15KB	~800 bytes	95%

Less tokens = faster responses, lower costs, more context for your AI.

Installation

npm install -g @cavort-it-systems/wordpress-mcp

Or run directly:

npx @cavort-it-systems/wordpress-mcp

Configuration

Claude Code CLI

claude mcp add wordpress \
  -e WORDPRESS_SITE_URL=https://example.com \
  -e WORDPRESS_USERNAME=admin \
  -e WORDPRESS_PASSWORD="xxxx xxxx xxxx xxxx" \
  -- npx @cavort-it-systems/wordpress-mcp

Claude Desktop / Manual

Add to your MCP config (~/.claude.json or Claude Desktop settings):

{
  "mcpServers": {
    "wordpress": {
      "command": "npx",
      "args": ["@cavort-it-systems/wordpress-mcp"],
      "env": {
        "WORDPRESS_SITE_URL": "https://example.com",
        "WORDPRESS_USERNAME": "admin",
        "WORDPRESS_PASSWORD": "xxxx xxxx xxxx xxxx"
      }
    }
  }
}

From Source

git clone https://github.com/cvrt-jh/wordpress-mcp.git
cd wordpress-mcp
npm install && npm run build

Authentication

Uses Application Passwords (WordPress 5.6+):

1. Go to Users → Profile in WordPress admin
2. Scroll to Application Passwords
3. Create new password for "Claude MCP"
4. Use the generated password (keep the spaces)

Response Slimming

All responses are automatically trimmed. Example:

wp_get_post — from ~5KB to ~200 bytes:

// Before (WordPress REST API raw)
{"id":123,"date":"2026-01-15T10:30:00","date_gmt":"2026-01-15T09:30:00",
"guid":{"rendered":"https://example.com/?p=123"},"modified":"2026-01-20T14:00:00",
"modified_gmt":"2026-01-20T13:00:00","slug":"my-post","status":"publish",
"type":"post","link":"https://example.com/my-post/","title":{"rendered":"My Post"},
"content":{"rendered":"<p>Full content...</p>","protected":false},
"excerpt":{"rendered":"<p>Excerpt...</p>","protected":false},
"author":1,"featured_media":456,"comment_status":"open","ping_status":"open",
"sticky":false,"template":"","format":"standard","meta":{"footnotes":""},
"categories":[1,5],"tags":[10,20],"class_list":["post-123","type-post",...],
"_links":{"self":[...],"collection":[...],"about":[...],...}}

// After (slimmed)
{"id":123,"title":"My Post","slug":"my-post","status":"publish",
"date":"2026-01-15T10:30:00","modified":"2026-01-20T14:00:00",
"link":"https://example.com/my-post/","excerpt":"Excerpt...",
"author":1,"categories":[1,5],"tags":[10,20],"featured_media":456}

What gets stripped:

Field	Where	Why
guid, _links	everywhere	Internal WordPress data
content.rendered	lists	Only included when explicitly requested
meta, class_list	posts/pages	Theme/plugin metadata
ping_status, comment_status	posts	Rarely needed
template, format, sticky	posts	Theme-specific
HTML tags	excerpts	Clean text output
Pretty-print JSON	all	Compact single-line output
