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 · Machine twin: /setup.md

1. Server

Add the CPG Knowledge Graph as a remote MCP server on your enterprise AI platform. Only two fields are needed.

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.

4. Migration statement

From the agent card's enforcement-posture extension (/.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.
