GMC YOOtheme MCP Lite

YOOtheme MCP Lite

Free limited companion to the GMC Pro product. This is a separate 0.1.2 client with a fresh history and only four read-only MCP tools. The Pro implementation is absent from this repository.

Lite is free to use under the limited commercial licence. Source visibility does not grant redistribution or resale rights.

Upgrade to Pro in your MCP client

Open the resource Upgrade to Pro (gmc://lite/pro-features) to see the capability comparison and the product's current plans. Editing, publishing, full import/export, bulk editing and restoration are labelled unavailable in Lite. They are informational previews; no Pro code or executable Pro tools are bundled. The free tools keep working without an upgrade.

MCP clients decide how resources are displayed, so this is not a guaranteed popup or a graphical settings panel. Ask your assistant to read the resource if its client does not expose a resource browser.

Guide and presentation

• Practical Lite guide (English): prerequisites, setup and a first read-only session.
• Presentation for clients (Italian PDF): a short overview of the three Lite clients and the separate Pro editions.
• Pro features and annual plans.

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 .

macOS/Linux:

.venv/bin/python -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

1. Copy sites.example.json to a local sites.json and keep only the sites you own or are authorized to access. The file is ignored by Git.
2. 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.
3. Set YOOTHEME_MCP_LITE_SITES to the absolute path of that local JSON file.
4. 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.
5. Start with yootheme_lite_list_sites, then yootheme_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 from layout.example.json as layout_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.
