Four read-only tools for GMC Builder site discovery and layout structure summaries

About

GMC Builder MCP Lite 0.1.1 is a free, limited local stdio companion for GMC Builder on Joomla and WordPress. It offers four read-only tools: configured site aliases, an authenticated connection probe, up to 10 builder element type names per call, and node/type counts from user-supplied local JSON (maximum 64 KiB).

Python 3.10+ and the separately obtained GMC Builder CMS product are required: WordPress authoring API 2.0.0+ or Joomla remote API 2.0.1+. Credentials stay in the user’s local environment. No authoring, publishing, full export/import, bulk editing, backups or private Pro source is included.

Free use is governed by LicenseRef-GMC-Lite-Commercial, not an open-source redistribution licence. This initial preview has had source and packaging inspection; runtime/site integration tests have not been performed.

The separate Pro product is sold by GMC. Pro Base is EUR 49 per year for up to 3 sites, with 12 months of updates/support and manual annual renewal. Contact gmcfuerte@gmail.com or visit https://fuerteventuratv.net/en/cms for the current offer.
