Neighbor protocols as a map: A2A, ACP, AP2, NLWeb, llms.txt — what is still a draft
Every week a new acronym shows up promising to make your site "AI-ready." Almost all of them are drafts or proposals, and each one lives in a different layer. In this lesson you place each neighbor protocol on the map, with a status and a date, and decide for your site: adopt, wait, or does not apply.
Start the lesson
In this lesson you will
- 1Which layer each acronym lives in
- 2Proposal, draft, project, and stable, with a date
- 3Adopt, wait, or does not apply, with a reason
- 4The reasons that don't count (ranking, "it will become a standard")
Goal: place each neighbor protocol in the right layer with a dated status, and decide adopt, wait, or does not apply, with a reason.
01Each acronym in its layer
Status read from the sources on 10/19/2026. Click each layer.
Click each block in the diagram to see what it does.
None of these is a ranking factor. Citation in AIs is a topic for the inemaSEO Track.
02How to read the status
The label tells you how much you can bet on it.
1. Proposal
Someone published the format; nobody has committed to reading it.
E.g., llms.txt. It costs little, but don't promise any effect.
2. Draft
A group document (CG, IETF) still in progress. The API has already changed once (navigator → document).
Adopting = review date + fallback, always.
3. Project
It has an implementation and an organization behind it (Linux Foundation, a company).
It is not stable: check the version on the day you adopt it.
4. Stable
A published, versioned revision, with a announced change (MCP 2026-07-28).
Even so, pin the SDK version and run the battery when it goes up.
Script rule
Adopting something that is not stable requires revisar_em (a date) and fallback.
03The decisions for the example site
One decision per protocol on the map, with a reason. Adopting something that is a draft takes a review date and a fallback.

}04Check the decisions against the map
vizinhos.mjs reads the dated map (vizinhos/mapa.json, with the source of each row) and your decisions file.

PROBLEMA Web Bot Auth: sem decisão
VIZINHOS: 8 protocolos · 7 decisões · 4 problema(s)
saída: 1"It will be the standard of the web" and "it moves the site up in the AI rankings" are not reasons: nothing on the map says that. Adopting WebMCP without a review date and without a fallback also fails.
05The rehearsal of bad decisions
The file vizinhos/ruim.json has four common problems.

E2 · The bad one fails
3 minRun the rehearsal of bad decisions and read the four problems.
Done when: The block prints VIZINHOS: 8 protocolos · 7 decisões · 4 problema(s) and saída: 1.
E3 · Your site's decisions
20 minCopy vizinhos/agenda-oficinas.json to vizinhos/meu-site.json and decide each protocol for your site, with your own reason. First, open the source of each row on the map and check whether the status has changed since 10/19/2026.

Question 1 of 4
Which protocol on the map was stable on 10/19/2026?
Correct
MCP has a published, versioned revision. WebMCP and Web Bot Auth are drafts; llms.txt is a proposal.Not this one

The site's workshops are free. What should you do with ACP and AP2?
Correct
These are purchase and payment layers. With no purchases on the site, they don't apply; if you ever start selling, the decision comes back with that day's date.Not this one

Why does "it raises the site in AI rankings" fail as a reason to adopt llms.txt?
Correct
The proposal exists (modified on 2026-08-10), but there is no measured effect on citation. Promising ranking is exactly what the WebMCP Track avoids.Not this one

You are going to adopt WebMCP on your site. What does the script require besides the reason?
Correct
A draft can change: revisar_em (YYYY-MM-DD) and fallback. There is no announced stable Chrome date, and browser positions are context (course 2), not a requirement.Not this one

08In three sentences
MapEach acronym lives in a layer: discovery, page, server, questions, agents, purchase, identity.
StatusProposal, draft, project or stable, always with the date you read it.
DecisionAdopt, wait or does not apply, with a reason; an adopted draft carries a date and a fallback.
