MCP CPG Agent Protocols

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.
