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/mcpRun this in your terminal
claude mcp add --transport http cpg-agent-protocols https://mcp.cpgagentprotocols.ai/mcpOr copy the settings yourself
Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json
{

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

Common questions
Is MCP CPG Agent Protocols safe?
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.
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?
In the same category: Spree Commerce: open-source B2B and marketplace ecommerce, Stripe MCP, MCP Cn Commerce

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.

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.
