Lite is free to use under the limited commercial licence. Source visibility does not grant redistribution or resale rights.
Prerequisites
Python 3.10 or newer. WordPress REST API with an Application Password, or Joomla Web Services with a token. YOOtheme remains a separately licensed product. The generic page list does not prove YOOtheme is installed; layout counts operate on JSON you supply.
Install from GitHub
git clone https://github.com/gmcfuerte/yootheme-mcp-lite.git
cd yootheme-mcp-lite
python -m venv .venv
Windows:
.venv\Scripts\python.exe -m pip install .

This Lite edition is distributed through this GitHub repository; it has not been published to PyPI. Do not install the separate full Pro package as a substitute for Lite.
Configure
- Copy
sites.example.jsonto a localsites.jsonand keep only the sites you own or are authorized to access. The file is ignored by Git. - Set the credential environment variables named by
username_env,password_env, and the applicable Joomla token/key field. Never put credential values in committed JSON or an MCP chat. - Set
YOOTHEME_MCP_LITE_SITESto the absolute path of that local JSON file. - Add the server using
mcp.example.json: replace the placeholders with the absolute Python executable and configuration file paths. Ensure the MCP client passes the credential variables to its child process. - Start with
yootheme_lite_list_sites, thenyootheme_lite_ping_site.
rest_mode: "query" supports WordPress without pretty REST URLs; otherwise
use pretty. Subdirectory installations are supported in the base URL.
Tools
yootheme_lite_list_sites: aliases and platforms only.yootheme_lite_ping_site: one authenticated GET, sanitized status only.yootheme_lite_list_pages: List at most ten page/article titles, ids and status; no content export.yootheme_lite_summarize_layout: pass the text fromlayout.example.jsonaslayout_json. Returns counts and types; no settings or content.
The server runs locally using stdio. No remote HTTP server, uploads, arbitrary URLs, SSH, license switch or Pro modules are included. Online tools use a fixed GET allowlist, verified TLS, no redirects, at most one request at a time per configured base URL, a two-second interval, and a 1 MiB response limit. HTTP is accepted only for exact loopback hosts. HTTP 403/415 stops subsequent requests to that base URL until restart.
Release status
Initial Lite release: source and package contents inspected and Python compiled. Site integration and runtime tests have not been performed. Do not treat this initial release as a production integration certification.
