# Enterprise setup — CPG Knowledge Graph connector

GreenCore Solutions Corp. (GSC) · Effective September 16, 2026 · Applies to the CPG Knowledge Graph MCP server at https://mcp.cpgknowledgegraph.ai/mcp · Human page: https://gsc-knowledgegraph.ai/setup

## 1. Server

- Server URL: https://mcp.cpgknowledgegraph.ai/mcp
- Transport: Streamable HTTP
- Name: CPG Knowledge Graph (GSC)
- Root document: https://mcp.cpgknowledgegraph.ai/

## 2. Authentication

None. Leave OAuth Client ID and Client Secret blank. There is no enterprise managed authentication to configure: the server does not issue a challenge, does not require a bearer token and does not run dynamic client registration. If your platform's connector form insists on an authentication method, choose "None" or "No authentication".

## 3. Scope of authority

Read, resolve and discovery tools are open: any connected agent may call them without credentials. Every transactional commit — an order, an RFQ acceptance, terms — is human-signed at the GSC Navigator boundary, https://gsc-navigator.ai/. Nothing settles without a person.

Tools: resolve_gtin · check_eligibility · get_signal_chain · count_gtin_coverage · resolve_scope · list_nodes · resolve_node · find_makers · find_retailers · node_market · list_sku_types · list_brands_by_node · get_kernel · resolve_sparks

## 4. Migration statement

From the agent card's enforcement-posture extension (https://gsc-knowledgegraph.ai/.well-known/agent-card.json, https://gsc-em.com/a2a/ext/enforcement-posture/v1), verbatim:

> These endpoints are open by design. When the buy side's credential standard reaches GA — expected Q4 2026-Q1 2027 — transactional methods migrate to OAuth 2.1 challenge per the MCP 2025-11-25 specification. Read access stays open. That is not pending work; that is the published plan.

```json
{
  "enforcement_posture": "open-by-declaration",
  "migration_standard": "OAuth 2.1 + PKCE challenge (401 + WWW-Authenticate) on mcp:transact methods, per MCP spec 2025-11-25",
  "migration_trigger": "ecosystem GA of credentialed counterparties (enterprise A2A/MCP buy-side GA)",
  "migration_window": "Q4 2026 - Q1 2027",
  "declared": "2026-08-24",
  "operator": "GreenCore Solutions Corp.",
