Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
AI visibility checker: GPTBot vs OAI-SearchBot, robots.txt audit, raw-HTML schema. 165 crawlers.
These three are never merged into one score: opinions, measurements and popularity are different things.

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.
The registry does not list a required key, though some servers ask you to sign in on first use.
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).

aivis 1.0.0 — can AI assistants read brooklinen.com?
Summary: 2 critical 2 to review 1 passed
That output is real, from a live page on a major DTC brand, reproduced across three independent fetches. Prefer a browser? Same checks, paste-based: [the web version](https://krisdiallo.github.io/ecom-agent/ai-visibility.html).
One page is an anecdote. Sample your catalogue to see whether a problem is systemic:
python3 aivis.py yourstore.com --pages 10
[FAIL] Structured data injected by JavaScript (7/10 pages)
[WARN] Fewer than 5 concrete measurements (9/10 pages) [ OK ] 1/10 pages clean on every check
This is a free GEO tool — generative engine optimization, also called LLM SEO or answer engine optimization: making sure an AI assistant can read your store well enough to cite or recommend it. It is the ecommerce-specific version of the broader AI search optimization question, focused on the two things that decide whether an answer engine can use your content at all:
OAI-SearchBot, PerplexityBot, Claude-SearchBot)? Most "block AI" advice gets this wrong by conflating them with training crawlers.If you searched for an AI visibility checker or a robots.txt checker for an ecommerce store, this does both, with primary-source data on 165 AI crawlers rather than generic advice.
An MCP server, so Claude Code, Claude Desktop, Cursor or any MCP client can run the check itself — "is my store readable by AI assistants?" answered in the conversation you're already in.
Nothing to download, no paths to edit — paste this into your MCP config:
{ "mcpServers": {
"aivis": { "command": "uvx", "args": ["--from", "git+https://github.com/krisdiallo/ecom-agent", "aivis-mcp"] } } }
Also listed in the [official MCP registry](https://registry.modelcontextprotocol.io) as io.github.krisdiallo/aivis, so any client that reads the registry can find it, and there is a one-file aivis_mcp.py in this repo if you would rather run it directly.
Stdio JSON-RPC, zero dependencies — the whole tool is standard library, which is why it can be fetched and run straight from git. It imports aivis.py rather than shelling out, so the CLI, web tool, study, GitHub Action and MCP server all share one verified implementation.
Catch it on the deploy that breaks it, not months later when you wonder why an assistant never mentions you:
- uses: krisdiallo/ecom-agent@v1
with: site: yourstore.com fail-on: critical # critical | warning | never
Writes a findings table to the job summary, exposes critical / warnings / passed / report as step outputs, and fails the build on real problems. This repo runs it against its own site on every push — a tool that tells you to check your AI visibility should be checking its own, in public.
--json works standalone too, if you'd rather wire it into something else:
python3 aivis.py yourstore.com --json --fail-on warning
There are two completely different kinds of AI crawler, and blocking them has opposite consequences:
| Kind | Tokens | If you block it |
|---|---|---|
| Search / answer | OAI-SearchBot PerplexityBot Claude-SearchBot Claude-User Amzn-SearchBot Amzn-User Applebot | You disappear from AI answers. |
| Training | GPTBot ClaudeBot Google-Extended CCBot Amazonbot Applebot-Extended meta-externalagent | Nothing changes in recommendations. A legitimate choice. |
Blocking `GPTBot` does not remove you from ChatGPT's recommendations. OAI-SearchBot is the token that does. The "block AI scrapers" wave conflated these, and a lot of sites opted out of training thinking they were protecting something else.
Three more that circulating robots.txt snippets routinely get wrong:
Amazonbot "may be used to train Amazon AI models"; Amzn-SearchBot is what makes you "eligible to appear in search experiences such as Alexa" and "does not crawl content for generative AI model training." Most guides name only the first. Block the wrong one and you lose Alexa for nothing.ai-robots-txt/ai.robots.txt (~4k stars) is the ecosystem's default answer to "block AI bots". Its generated robots.txt disallows all 166 known AI user-agents. Audited with this tool:
$ python3 -c "import aivis,urllib.request as u; \
print(aivis.audit_robots(u.urlopen('https://raw.githubusercontent.com/\ ai-robots-txt/ai.robots.txt/main/robots.txt').read().decode()))"
visible_to_ai_search: False blocked_search : OAI-SearchBot, PerplexityBot, Claude-SearchBot, Claude-User, Amzn-SearchBot, Amzn-User, Applebot
That is deliberate on their part, and correct for their audience. Their FAQ states the position plainly: these crawlers are *"extractive, confer no benefit to the creators of data they're ingesting."* A publisher who does not want ChatGPT answering questions from their articles without a click wants exactly this file. We are not describing a bug, and an earlier version of this section wrongly implied one.
The point is that blocking AI is two decisions, not one, and a single list collapses them:
A publisher usually wants both. An ecommerce store usually wants the first and not the second — being absent from AI answers is lost demand, not protected work. If that is you, this generates the other file:
python3 aivis.py --training-optout >> robots.txt
Blocks all 8 training crawlers, leaves all 7 search crawlers allowed. Verified in CI by auditing our own generated output.
If you're building a GEO tool, a crawler, or a shopping agent, you probably want the primitive rather than the report:
from aivis import classify_crawler, audit_robots
classify_crawler("GPTBot")["blocking_effect"] # 'opts_out_of_training_only' classify_crawler("OAI-SearchBot")["blocking_effect"] # 'removes_from_ai_answers' classify_crawler("SomeRandomBot") # None — it won't guess
r = audit_robots(open("robots.txt").read()) r["visible_to_ai_search"] # False if any AI *search* crawler is blocked r["blocked_search"] # the ones that actually cost you answers r["blocked_training"] # blocking these costs nothing; listed separately on purpose
audit_robots applies real group precedence — a crawler obeys its own group and ignores User-agent: * when it has one — and classifies paths so a stock Shopify file, with its ~45 default Disallow rules, doesn't read as broken.
Every classification is sourced to the vendor's own documentation (crawlers.json carries the quotes and dates), and research/test_api.py is a contract test in CI so the values can't drift. Zero dependencies: pip install git+https://github.com/krisdiallo/ecom-agent.
agent-commerce.json — which stores an AI agent can actually buy from[`agent-commerce.json`](agent-commerce.json) — 70 storefronts probed, 49 expose a live endpoint an agent can call to search a catalogue, build a cart and complete a checkout, bypassing HTML entirely.
The result worth the file: all 49 exposed an identical 13-tool surface on one UCP version. Zero variation across 49 independent brands.
That means agent-commerce capability is currently a property of the platform, not a merchant choice. A store has it because its platform switched it on. Two consequences:
# every store in the sample an agent can transact with
curl -s https://raw.githubusercontent.com/krisdiallo/ecom-agent/main/agent-commerce.json \ | python3 -c "import json,sys;[print(h['host']) for h in json.load(sys.stdin)['hosts'] if h['agent_commerce']]"
A live endpoint does not mean any agent can buy. Probing further: tools/list answers anonymously, but every tool *call* is refused without a published UCP agent profile URI (invalid_profile_url), verified on three independent stores. So these stores are transactable by identified agents, not anonymous ones — capability enumeration is open, transacting is not. That is an accountability layer worth knowing about, and our first phrasing was too strong.
We did not create an agent profile to test past it. Manufacturing an identity in order to transact on someone else's storefront is not something we will do for a cleaner dataset.
Probe was read-only throughout: tools/list only. It never created a cart or started a checkout.
crawlers.json — the data behind all of this[`crawlers.json`](crawlers.json) is the machine-readable registry the tools are built on: 21 tokens, each with its vendor, purpose, what blocking it actually does, whether it honours robots.txt, the vendor's own words, a source URL, and the date it was checked.
# every token whose blocking removes you from AI answers
curl -s https://raw.githubusercontent.com/krisdiallo/ecom-agent/main/crawlers.json \ | python3 -c "import json,sys;[print(c['token']) for c in json.load(sys.stdin)['crawlers'] \ if c['blocking_effect']=='removes_from_ai_answers']"
Three entries (CCBot, Bytespider, Amazonbot's siblings aside) could not be tied to a first-party quote; those carry an explicit verification flag rather than being dressed up as sourced. research/test_consistency.py fails the build if the CLI and the registry ever disagree — which is how the Amazon misclassification above was caught before publication.
