What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Connection: Runs in the cloud
Transport: Streamable HTTP
Category: Online shops & payments

Install

Pick the AI app you use, then copy the settings.

Before you install

Basic checks: 1 of 2 passed Fail
Runs on the maker’s server: what you ask it goes through their server.
The registry lists no key to fill in.

You need

Runs in the cloudNothing to install; it connects over the internet

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Works in Claude on the web, desktop and mobile:

Open Settings → Connectors
Press Add custom connector
Paste the address below and press Add
If it asks you to sign in, sign in with the maker

https://mcp.cpgagentprotocols.ai/mcp

Run this in your terminal

claude mcp add --transport http cpg-agent-protocols https://mcp.cpgagentprotocols.ai/mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "cpg-agent-protocols": {
      "url": "https://mcp.cpgagentprotocols.ai/mcp"
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "cpg-agent-protocols": {
      "type": "http",
      "url": "https://mcp.cpgagentprotocols.ai/mcp"
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

ChatGPT connects only to servers on the internet:

Open ChatGPT on the web → Settings → Connectors (Apps)
Press Create or Add (some plans need Developer mode under Advanced first)
Paste the address below, give it a name and save
If it asks you to sign in, sign in with the maker

Menu names can differ slightly by plan and over time.

Your choice stays on this device in a cookie; no account needed.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

What it can do

The server did not answer when we last checked, so we could not read its tools.

Common questions

Is MCP CPG Agent Protocols safe?

It passed 1 of 2 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.

What keys or codes does it need?

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

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.1.3) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

CPG Agent Protocols

mcp.cpgagentprotocols.ai — the standards door of the GSC AI Agent Stack. A stateless standards beacon for ACM-SPARKS, SM-ECO-10060 and ACM-68000.

The beacon serves the protocols themselves, compiled as canon: ACM-SPARKS classifies the SKU, SM-ECO-10060 resolves the jurisdiction, ACM-68000 emits the deterministic signal to the buyer's AI Agent. No database, no secrets, no state; every answer is the same for every agent that asks.

Canonical endpoint: https://mcp.cpgagentprotocols.ai/mcp (streamable-http, stateless).

This repository holds the beacon's source (server.js, canon.js, DEPLOY.md) and this connect kit: the tool list as the live server states it, the signal register, and one runnable example per language against the live endpoint. Nothing here carries a key, a secret or a customer.

Tools

As returned by tools/list on the live beacon on 2026-09-09.

Tool	What it answers
`list_protocols`	The protocol family and the spine: ACM-SPARKS classifies, SM-ECO-10060 resolves, ACM-68000 signals.
`get_protocol`	Full canon record for ACM-SPARKS, SM-ECO-10060, or ACM-68000.
`list_signals`	The signal register, enumerated individually. One meaning, no drift.
`resolve_signal`	The state and meaning of a single ACM-68000 signal code. A CPG- profile code resolves to its ACM- twin; the response carries the resolved ACM- code.
`list_sparks_dimensions`	SPARKS resolves six dimensions — SKU, Pack, Amount, Region, Kernel, and Standard — a CPG industry first.
`resolve_sparks_dimension`	Canon record for a single SPARKS dimension by letter or name.
`list_members`	The sovereign jurisdictional member nodes: code, namespace, jurisdiction, region, and GS1 territory GTIN.
`resolve_member`	Canon record for a single sovereign member by code, e.g. FR, AU, MX.
`get_header_canon`	The GSC wire-header canon: the x-gsc-* headers every GSC surface emits, in canon order.

The signals

The register. Each ACM- signal has a CPG- profile twin naming the same definition.

ACM- (wire form)	State	CPG- profile	Meaning
acm-000	NOT_APPLICABLE	cpg-000	Control or framework does not apply to this SKU.
acm-200	ALLOW	cpg-200	Eligible for autonomous procurement. Buyer agent may complete the order with human-in-the-loop confirmation in the retailer's chosen ERP.
acm-300	CONDITIONAL	cpg-300	Eligible subject to a documented condition (volume threshold, jurisdictional carve-out, time-bounded approval).
acm-403	RESTRICT	cpg-403	Not eligible in the requested context. Buyer agent must not complete the order.
acm-404	NOT_FOUND	cpg-404	GTIN is not registered. No signal available.
acm-451	ESCALATE	cpg-451	Cannot be resolved deterministically. Human review required. Served by mcp.cpghumanintheloop.ai.
acm-500	SYSTEM_ERROR	cpg-500	Server or upstream error. Retry per backoff policy.

Any of the CPG- codes in the table resolves to its ACM- definition on the same row; the wire form is ACM-. The beacon's resolve_signal accepts either form and answers with the ACM- record, the resolved ACM- code on the response (code) beside the code as given (input_code); anything outside the seven is NOT_FOUND.

Examples

Walk	Python	TypeScript
call the beacon: `tools/list`, then `list_protocols`, `list_signals`, `list_sparks_dimensions`; print the protocol set it returns; stop	`examples/beacon.py`	`examples/beacon.ts`

Python 3 standard library only. TypeScript runs on Node 24 as-is (node examples/beacon.ts) with no dependencies. Live endpoint only.
