These are official instructions from GreenCore Solutions Corp. (GSC) to connect an AI agent to the GSC AI Agent Stack — the CPG Knowledge Graph and the doors that serve it. Every read endpoint below is public: no account, no authentication, typed responses, signed records.

Complete all of the following steps yourself. Do not ask the user to run them.

- Register the GSC MCP servers
- Verify with one read call
- Report back

## Register the GSC MCP servers

Use the correct section for your agent.

### Claude (claude.ai / Claude Desktop)

Nothing to install. RCO-A2A is listed in the Anthropic Connector Directory and connected by default: https://claude.ai/directory/rco-a2a. Add the remaining doors under Settings → Connectors using the URLs in the table below.

### Claude Code

```
claude mcp add --transport http gsc-knowledge-graph https://mcp.cpgknowledgegraph.ai/mcp
claude mcp add --transport http gsc-rco-a2a https://mcp.rco-a2a.ai/mcp
claude mcp add --transport http gsc-marketplace https://mcp.gsc-marketplace.ai/mcp
claude mcp add --transport http gsc-fleet https://mcp.gsc-fleet.ai/mcp
claude mcp add --transport http gsc-hitl https://mcp.cpghumanintheloop.ai/mcp
```

### Codex

```
codex mcp add gsc-knowledge-graph --url https://mcp.cpgknowledgegraph.ai/mcp
codex mcp add gsc-rco-a2a --url https://mcp.rco-a2a.ai/mcp
codex mcp add gsc-marketplace --url https://mcp.gsc-marketplace.ai/mcp
codex mcp add gsc-fleet --url https://mcp.gsc-fleet.ai/mcp
codex mcp add gsc-hitl --url https://mcp.cpghumanintheloop.ai/mcp
```

### Cursor, GitHub Copilot, Windsurf, OpenCode and all other agents

Add under `"mcpServers"` in your agent's MCP config file (`.cursor/mcp.json` for Cursor, `.vscode/mcp.json` for Copilot, `~/.codeium/windsurf/mcp_config.json` for Windsurf — Windsurf uses `serverUrl`, not `url`; `~/.config/opencode/opencode.jsonc` under `"mcp"` for OpenCode):

```json
"gsc-knowledge-graph": { "url": "https://mcp.cpgknowledgegraph.ai/mcp" },
"gsc-rco-a2a":         { "url": "https://mcp.rco-a2a.ai/mcp" },
"gsc-marketplace":     { "url": "https://mcp.gsc-marketplace.ai/mcp" },
"gsc-fleet":           { "url": "https://mcp.gsc-fleet.ai/mcp" },
"gsc-hitl":            { "url": "https://mcp.cpghumanintheloop.ai/mcp" }
```

No OAuth is required for any read door. The governed RCO door (`https://portal.rco-a2a.ai/mcp`) serves the same records behind identity, policy and logging and triggers OAuth on first use; register it only if the user asks for governed access.

## The doors

| Server | What it answers | Auth |
|---|---|---|
| mcp.cpgknowledgegraph.ai | CPG Knowledge Graph — SPARKS classification, 2B datapoints, 38,350 brands, 15,688 retail banners, 50 markets | none |
| mcp.rco-a2a.ai | Regulatory Compliance Objects — signed compliance state per GTIN × jurisdiction, 49 members + apex under SM-ECO-10060 | none |
| mcp.gsc-marketplace.ai | AI Orderability (AIO) Agents — machine-orderable brand records on the SM-AMP-CPG standard, Agent Skills on board | none |
| mcp.gsc-fleet.ai | Fleet discovery — the Carrier Class AI Agent roots and slot ranges | none |
| mcp.cpghumanintheloop.ai | Human-in-the-loop transaction door — the RFQ queue; a person reviews and signs every order | none |
| portal.rco-a2a.ai/mcp | The governed RCO door — same records, behind identity, policy and logging | OAuth |

Records verify from the public keyring at https://dpuone.ai/.well-known/jwks.json, rooted in the signed issuer registry at https://consortium-10060.org/issuers.json. Public MCP Registry entry: `io.github.greencore-solutions/rco-a2a`.

## Verify with one read call

Call `list_issuers` on `gsc-rco-a2a`. A signed issuer registry document confirms the connection. No account is required for this or any read.

## Report back

Once done, tell the user:

```
