> Which Magento and PHP versions each angeo module supports, read from every package's composer.json and checked against Packagist. Source: https://angeo.dev/docs/compatibility/ Updated: 2026-09-25 # Module compatibility matrix **Every angeo module, its latest version, and the Magento and PHP versions it declares support for.** Constraints are read from each package's `composer.json`, not from a hand-maintained list. If a constraint here disagrees with what Composer does, the constraint in the package is the truth and this page is stale. Checked on 11 September 2026. Latest versions are the ones published on Packagist; constraints are read from `composer.json` at that version. The Magento range is derived from *all* declared `magento/*` constraints, not only `magento/framework`: framework 103.0.x and `module-catalog` 104.0.x both correspond to Magento 2.4.x. ## The matrix | Module | Latest | Magento | PHP | Requires | PHP extensions | | aeo-audit | 4.2.2 | 2.4.x | 8.2 - 8.4 | - | - | | aeo-brand-visibility | 4.0.0 | 2.4.x | 8.2 - 8.4 | `aeo-audit ^3.0 || ^4.0` | - | | ai-description-updater | 1.1.0 | not declared | 8.2+ | - | - | | llms-txt | 4.3.0 | 2.4.x | 8.2 - 8.5 | - | `json`, `mbstring` | | mcp-server | 2.2.1 | 2.4.6+ | 8.1 - 8.4 | - | - | | mcp-checkout | 2.1.2 | 2.4.6 - 2.4.x | 8.1 - 8.4 | `mcp-server ^2.2` | - | | openai-product-feed | 2.1.0 | not declared | 8.1+ | MSI (`magento/module-inventory-sales-api`) | - | | openai-product-feed-api | 2.0.1 | not declared | 8.1+ | `openai-product-feed ^2.0` | - | | rich-data | 2.0.0 | 2.4.x | 8.2 - 8.5 | - | - | | robots-txt-aeo | 4.0.0 | 2.4.x | 8.2 - 8.5 | - | `json`, `sodium` | | ucp | 2.1.0 | 2.4.x | 8.2+ | - | `curl`, `json`, `openssl` | | ucp-catalog | 2.1.0 | 2.4.6+ | 8.2 - 8.4 | `ucp ^2.1` | `json`, `mbstring` | Scroll the table horizontally on narrow screens. "8.2+" means the package declares no upper PHP limit. Composer will install it on newer PHP versions, but they have not necessarily been tested. **Retired:** `angeo/module-openai-instant-checkout` is marked as abandoned on Packagist and is no longer listed here. OpenAI moved away from checkout inside ChatGPT in 2026. The suggested replacement is [mcp-checkout](https://angeo.dev/modules/mcp-checkout/). ## The constraints that decide the whole install Composer installs only what fits every constraint at once, so the narrowest module in a set decides what the store can run. **PHP 8.2, 8.3 and 8.4 run every module.** The edges are narrower: - **PHP 8.1:** only `mcp-server`, `mcp-checkout`, `openai-product-feed` and `openai-product-feed-api` install. Everything else now requires 8.2. - **PHP 8.5:** `aeo-audit`, `aeo-brand-visibility`, `mcp-server`, `mcp-checkout` and `ucp-catalog` stop at 8.4. **Magento 2.4.6 or later runs every module.** Three modules require it: `mcp-server`, `mcp-checkout` and `ucp-catalog`. On 2.4.0 - 2.4.5 everything else installs. `mcp-checkout` also caps below the next major framework version, so it installs on 2.4.x only. **No module supports Magento 2.3 any more.** `llms-txt` still declares `magento/framework >=102.0`, but it also requires `magento/module-catalog >=104.0`, which exists only from 2.4.0. **`openai-product-feed` needs Multi-Source Inventory.** It requires `magento/module-inventory-sales-api`, so it will not install on a store that removed the MSI modules. `openai-product-feed-api` inherits this through its dependency. Practical reading: a store on Magento 2.4.6+ with PHP 8.2, 8.3 or 8.4 and MSI enabled can run the whole suite. ## Dependency chains Four modules depend on another angeo package. Composer installs these automatically, but the chain matters when you pin versions or plan an upgrade: ``` aeo-brand-visibility -> aeo-audit ^3.0 || ^4.0 mcp-checkout -> mcp-server ^2.2 openai-product-feed-api -> openai-product-feed ^2.0 ucp-catalog -> ucp ^2.1 ``` Everything else is standalone. The `suggest` entries in each package are recommendations, not requirements: Composer does not install them, and nothing breaks without them. ## Installing All packages are MIT licensed and published on Packagist under the `angeo/` namespace. ``` # A single module composer require angeo/module-llms-txt bin/magento module:enable Angeo_LlmsTxt bin/magento setup:upgrade # The readability layer - a sensible starting point composer require angeo/module-robots-txt-aeo \ angeo/module-llms-txt \ angeo/module-rich-data \ angeo/module-aeo-audit bin/magento setup:upgrade # Check what Composer would actually resolve for your store composer why-not angeo/module-ucp-catalog 2.1.0 ``` ## Questions Which PHP version runs the whole suite? PHP 8.2, 8.3 or 8.4. On PHP 8.1 only the MCP and product feed modules install, and on PHP 8.5 aeo-audit, aeo-brand-visibility, the MCP modules and ucp-catalog do not. Which Magento version runs the whole suite? Magento 2.4.6 or later. Three modules require it: mcp-server, mcp-checkout and ucp-catalog. On earlier 2.4 releases the other modules still install. No module supports Magento 2.3. Do these work on Adobe Commerce as well as Magento Open Source? Yes. The constraints are on magento/framework and magento/module-* packages that both editions share, and no module depends on a Commerce-only package. Why do some rows say the Magento version is not declared? openai-product-feed, openai-product-feed-api and ai-description-updater currently accept any magento/framework version, so Composer will not stop them installing on a version they were never tested against. Treat them as 2.4.x in practice. What happened to openai-instant-checkout? It is abandoned. OpenAI moved away from checkout inside ChatGPT in 2026, so the module implemented a flow that ordinary merchants can no longer use. The suggested replacement is mcp-checkout. Is this list generated or maintained by hand? The values are read from each published package and checked against Packagist on the date at the top. The package itself is always authoritative; this page is a convenience view of it. ## More on this topic - [Docs](https://angeo.dev/docs/) - [AEO Audit Skill - Audit Any Website for AI Visibility](https://angeo.dev/docs/aeo-audit-skill/) - [AI Crawlers for Magento 2: GPTBot, OAI-SearchBot & More](https://angeo.dev/docs/ai-crawlers/) - [MCP Modules for Magento 2 - Configuration Reference](https://angeo.dev/docs/mcp/) - [MCP Checkout for Magento 2: Claude, ChatGPT, Perplexity](https://angeo.dev/docs/mcp-checkout/) - [MCP & Agentic Commerce Glossary for Magento 2](https://angeo.dev/docs/mcp-glossary/) ## Sources - [angeo packages on Packagist](https://packagist.org/packages/angeo/) - [angeo-dev on GitHub](https://github.com/angeo-dev) Links checked 23 September 2026.
