It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
Is it still maintained?

Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need MCPB on your computer.

GMC Builder MCP Lite
Free limited companion to the GMC Pro product. This is a separate 0.1.3 client with a fresh history and only four read-only MCP tools. The Pro implementation is absent from this repository.
Lite and Pro
| Capability | Lite | Pro product |
|---|---|---|
| Configured site aliases | Yes | Yes |
| Authenticated connection probe | Yes | Yes |
| Up to 10 element types per call | Yes | Extended tools |
| Local supplied JSON: node counts/types | Yes, input up to 64 KiB | Detailed inspection |
| Create/edit/publish layouts or documents | No | Paid functionality |
| Full export/import, bulk editing, backups | No | Paid functionality |
| Private Pro implementation or CMS companion source | Absent | Separately distributed |
See Pro features and current annual plans. Contact gmcfuerte@gmail.com for companion requirements or product questions.
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. GMC Builder installed on the target site: WordPress authoring API (2.0.0+) with an Application Password, or Joomla remote API (2.0.1+) with the shared X-Gmc-Builder-Key. This repository does not distribute GMC Builder. Obtain the CMS product through GMC; no layout-export endpoint is included in Lite.
Install from GitHub
git clone https://github.com/gmcfuerte/gmcbuilder-mcp-lite.gitcd gmcbuilder-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
- 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
GMCBUILDER_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
gmcbuilder_lite_list_sites, thengmcbuilder_lite_ping_site.
rest_mode: "query" supports WordPress without pretty REST URLs; otherwise use pretty. Subdirectory installations are supported in the base URL.
Tools
gmcbuilder_lite_list_sites: aliases and platforms only.gmcbuilder_lite_ping_site: one authenticated GET, sanitized status only.gmcbuilder_lite_list_element_types: List at most ten builder element type names; no schema or kit export.gmcbuilder_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
Version 0.1.3 fixes line breaks in the capability-comparison resource; the four tools remain read-only and no Pro editing code is included. The release notes record scoped checks of current CMS read probes and exact MCPB uv startup on Windows/Python 3.13.
These checks do not certify graphical-host installation, macOS/Linux, production use or every upstream vendor feature. CMS requests still require the separate GMC Builder extension and its authorized API access; Lite contains no authoring or export endpoints.
