# Modules > Twelve free MIT-licensed Magento 2 modules for AI visibility: AEO audit, llms.txt, AI crawler rules, JSON-LD, ChatGPT feed, MCP and UCP. Source: https://angeo.dev/modules/ Updated: 2026-10-19 Open source - MIT - Magento 2.4.x # Seventeen modules that make a Magento 2 store *readable, quotable and purchasable* by AI. Every AEO signal an AI engine checks has one module behind it. Install only the piece you are missing. No licence key, no admin account, no telemetry - and nearly 7,000 installs of the llms.txt module alone, all countable on Packagist. # step 1 - find out what you actually fail $ composer require angeo/module-aeo-audit $ bin/magento setup:upgrade $ bin/magento angeo:aeo:audit # or: the tested core set in one package $ composer require angeo/agentic-commerce-suite Most stores fail two or three signals, not all of them. Start with the audit. The [Agentic Commerce Suite](https://angeo.dev/modules/agentic-commerce-suite/) installs eleven core modules together; add the others when you need them. 01 ## Measure first Find out what AI engines and agents see before you change anything. All three only read data. ### angeo/[module-aeo-audit](https://angeo.dev/modules/aeo-audit/) A read-only CLI audit. It scores 20 AI-visibility signals for every store view and prints the command that fixes each failure. - Twenty signals, one command - Severity, not just pass or fail - Real field performance (CrUX) CLICI readyMIT composer require angeo/module-aeo-audit [Docs](https://angeo.dev/modules/aeo-audit/) [GitHub](https://github.com/angeo-dev/module-aeo-audit) [Packagist](https://packagist.org/packages/angeo/module-aeo-audit) ### angeo/[module-aeo-brand-visibility](https://angeo.dev/modules/aeo-brand-visibility/) Asks ChatGPT, Claude, Perplexity, Gemini and Groq real buying questions.

Everything else depends on these three. ### angeo/[module-robots-txt-aeo](https://angeo.dev/modules/robots-txt-aeo/) Manages AI crawler rules in robots.txt from the admin - OAI-SearchBot, GPTBot, ChatGPT-User, PerplexityBot, Google-Extended, ClaudeBot, Claude-SearchBot, Applebot-Extended, CCBot and more - without breaking the rules you already have. - Lossless round-trip parsing - A current bot catalogue - Usage terms, not just access RFC 9309Content-UsageRSL 1.0MIT composer require angeo/module-robots-txt-aeo [Docs](https://angeo.dev/modules/robots-txt-aeo/) [GitHub](https://github.com/angeo-dev/module-robots-txt-aeo) [Packagist](https://packagist.org/packages/angeo/module-robots-txt-aeo) ### angeo/[module-llms-txt](https://angeo.dev/modules/llms-txt/) Generates llms.txt and llms-full.txt to the llmstxt.org v2 spec, plus streaming JSONL and agents.md.

MCP is a live connection: an agent asks your store a question and gets current data back. ### angeo/[module-mcp-server](https://angeo.dev/modules/mcp-server/) An MCP server that gives AI agents live, rate-limited access to your catalogue: product search, product cards, categories and store info. - Speaks MCP 2026-07-28 and earlier - Read-only by default - Rate limited at the server MCPRead-onlyMIT composer require angeo/module-mcp-server [Docs](https://angeo.dev/modules/mcp-server/) [GitHub](https://github.com/angeo-dev/module-mcp-server) [Packagist](https://packagist.org/packages/angeo/module-mcp-server) ### angeo/[module-mcp-checkout](https://angeo.dev/modules/mcp-checkout/) Adds guest cart and checkout tools to the MCP server, so an agent goes from search to a placed order in one conversation. - Six tools, one complete flow - Guardrails on the server, not in the prompt - Guest checkout by design MCPGuest checkoutMIT composer require angeo/module-mcp-checkout [Docs](https://angeo.dev/modules/mcp-checkout/) [GitHub](https://github.com/angeo-dev/module-mcp-checkout) [Packagist](https://packagist.org/packages/angeo/module-mcp-checkout) ### angeo/[module-mcp-reorder](https://angeo.dev/modules/mcp-reorder/) Tools for signed-in buyers.

The buyer always pays on your own checkout. ### angeo/[module-ucp](https://angeo.dev/modules/ucp/) Publishes a signed Universal Commerce Protocol profile at /.well-known/ucp, so an agent can verify the merchant before it acts. - Spec 2026-08-25 - keys[] JWK Set (ES256, ES384, Ed25519) - Correct hosting and CORS headers UCP/.well-knownMIT composer require angeo/module-ucp [Docs](https://angeo.dev/modules/ucp/) [GitHub](https://github.com/angeo-dev/module-ucp) [Packagist](https://packagist.org/packages/angeo/module-ucp) ### angeo/[module-ucp-catalog](https://angeo.dev/modules/ucp-catalog/) Implements catalog.search, catalog.lookup and get_product - the endpoints your UCP profile advertises. - Makes the profile honest - Real configurable variants - Spec 2026-08-25 UCPRESTMIT composer require angeo/module-ucp-catalog [Docs](https://angeo.dev/modules/ucp-catalog/) [GitHub](https://github.com/angeo-dev/module-ucp-catalog) [Packagist](https://packagist.org/packages/angeo/module-ucp-catalog) ### angeo/[module-ucp-checkout](https://angeo.dev/modules/ucp-checkout/) Agents create, update and cancel real checkout sessions over REST, with live shipping rates.

Yes. All seventeen are MIT-licensed and published on Packagist and GitHub. There is no paid tier, licence key or usage limit. Angeo earns from audits, implementation and ongoing monitoring. ### Which module should I install first? angeo/module-aeo-audit. It is read-only and reports which AEO signals pass and which fail, so you install only the modules that close a real gap. Most stores fail two or three signals. ### Do I need all seventeen? Almost certainly not. The audit plus the three access and structure modules decide whether AI engines can read your store at all. The MCP and UCP modules matter when you want agents to search and buy, which is a later stage for most merchants. ### What is the Agentic Commerce Suite? One Composer package that installs eleven core modules as a tested set: llms.txt, robots.txt, rich data, the audit, the product feed, UCP profile, catalog and checkout, MCP server, MCP checkout and WebMCP. ### Does an AI agent ever take payment? No card data goes through the agent. UCP Checkout hands the buyer to your own checkout page, and MCP Checkout ends with a payment link from your own payment provider. ### Do they work on Adobe Commerce Cloud? Yes, on Magento Open Source and Adobe Commerce 2.4.x with PHP 8.2 or later. On Cloud, purge the Fastly cache after changing robots.txt, or AI crawlers keep reading the cached version. ### Will they slow down the storefront? Generation runs on cron and CLI, not on page render, with batched queries so large catalogues do not exhaust memory or lock tables. The MCP server is rate limited on the server. ### Does installing these guarantee ChatGPT will recommend my store? No, and anyone promising that is selling something. The modules fix the signals a merchant controls: crawler access, structured data, a conforming feed, a verifiable profile, live agent access. Whether an engine then recommends you also depends on price, reviews and third-party coverage no module can produce. ## Not sure which signals you are failing? Run the free web scanner for a score in a few seconds, or install the CLI audit and get the same check across every store view, with the fix command for each failure.
