# 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** - 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](https://github.com/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)

```bash
uvx mcp-wordpress-crunchtools
```

### With pip

```bash
pip install mcp-wordpress-crunchtools
mcp-wordpress-crunchtools
```

### With Container

```bash
# 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.
