MCP WordPress CrunchTools

A secure MCP (Model Context Protocol) server for WordPress content management. Designed for developers publishing about their work.

Overview

This MCP server is designed to be:

• Secure by default - Comprehensive input validation, credential protection, and SSRF prevention
• No third-party services - Runs locally via stdio, your credentials never leave your machine
• Cross-platform - Works on Linux, macOS, and Windows
• Automatically updated - GitHub Actions monitor for CVEs and update dependencies
• Containerized - Available at quay.io/crunchtools/mcp-wordpress

Naming Convention

Component	Name
GitHub repo	crunchtools/mcp-wordpress
Container	quay.io/crunchtools/mcp-wordpress
Python package (PyPI)	mcp-wordpress-crunchtools
CLI command	mcp-wordpress-crunchtools
Module import	mcp_wordpress_crunchtools

Features

• 30 Tools for posts, pages, media, and comments
• Security-focused: Credentials protected, input validation, SSRF prevention
• Developer workflow: Scheduled publishing, revisions, search
• Easy integration: Works with Claude Code and other MCP clients

Installation

With uvx (recommended)

uvx mcp-wordpress-crunchtools

With pip

pip install mcp-wordpress-crunchtools
mcp-wordpress-crunchtools

With Container

# Create a shared upload directory (required before first run)
mkdir -p ~/.local/share/mcp-uploads-downloads

podman run -v ~/.local/share/mcp-uploads-downloads:/tmp/mcp-uploads:z \
  -e WORDPRESS_URL=https://example.com \
  -e WORDPRESS_USERNAME=admin \
  -e WORDPRESS_APP_PASSWORD='xxxx xxxx xxxx xxxx' \
  quay.io/crunchtools/mcp-wordpress

SELinux note: Use :z (lowercase, shared) instead of :Z (uppercase, private). MCP servers run as long-lived stdio processes. With :Z, files copied into the directory after container start won't have the container's private MCS label and will be invisible inside the container. The :z flag sets a shared container_file_t context that all containers and the host can read/write.

Tip: Use the same shared directory (~/.local/share/mcp-uploads-downloads/) across multiple MCP container servers (e.g., mcp-wordpress and mcp-gemini) so generated files are immediately available for upload without copying.
