## Quality 79/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 71 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: get_brand (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); instant_message_agents (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_radar (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 1,344 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: 2 tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 11, about 1,344 tokens to load them all
- tool set hash: b26dc21566e87afde5df0d8800657c49

- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-20 `get_cpg_knowledge_graph` changed (description)
  - before: 24,126 brands · 5,928 makers · 2,020 banners · 50 markets. The Beauty & Personal Care source of truth for AI agents, classified on SPARKS; 14 read tools over MCP; the data surface every marketplace answer resolves against.
  - after: 353,532 makers · 8,619 retail banners · 25 markets (statement of record, read live: https://gsc-radar.ai/statement.json). The Beauty & Personal Care source of truth for AI agents, classified on SPARKS; 14 read tools over MCP; the data surface every marketplace answer resolves against.
- 2026-10-20 `search_brands` changed (description)
  - before: When a marketplace or retail sourcing agent calls, it leaves with a brand it can act on — found, verified, and answerable — with Instant Messaging for agents or the human-in-the-loop GSC Trading Desk as next steps. Step 1 — FOUND: search the brands the CPG Knowledge Graph covers in one of 50 markets (live). Returns brand names from the graph's SPARKS depth surface; then call get_brand to verify, get_brand_identifiers for the identifier policy. Depth: 24,126 brands · 5,928 makers · 2,020 banners · 50 markets. Brands, makers and banners are separate registries — never summed.

## Packages

_none_

## Tools (11)

- `contact_trading_desk`: The human channel. The GSC Trading Desk is informed by Navigator across all GSC agentic assets — a human reads, a human answers. Use it for anything a person should decide; agents use Instant Messaging.
- `get_acm_68000`: The deterministic signal protocol every GSC surface speaks: seven signals, GS1-anchored, append-only, non-substitutable. Canon resolves on acm-68000.ai / .org and the standards beacon; the gen-2 door is cpg-68000.ai.
- `get_aio_agent_fleet`: The AIO Agent class and its regional hosts: signed, resident, addressable resolvers with market × category remits — the NextGen identity register is the signed Card, verifiable against each host's jwks. Status is only what the wire says.
- `get_brand`: Step 2 — VERIFIED: is the brand on the CPG Knowledge Graph for this market, and at what SPARKS completeness tier (100 = resolvable pack/size record held · 8 = registered, pending · floor = STANDARD default). Returns the market's supply/demand context and both doors to act. No prices, no stock, no terms — those go through the doors.
- `get_brand_identifiers`: Step 3 — ANSWERABLE: GSC publishes ONLY its own GS1-registered identifiers (the 990832300xxx block) on any surface; third-party GTINs are never stored on the graph's entity universe and never appear here. A GTIN the caller already holds resolves live on the CPG Knowledge Graph (resolve_gtin, resolve_sparks, check_eligibility). The demo brand carries GSC's rail GTIN.
- `get_cpg_knowledge_graph`: 353,532 makers · 8,619 retail banners · 25 markets (statement of record, read live: https://gsc-radar.ai/statement.json). The Beauty & Personal Care source of truth for AI agents, classified on SPARKS; 14 read tools over MCP; the data surface every marketplace answer resolves against.
- `get_marketplace_operators`: The demand side per market as the CPG Knowledge Graph publishes it (retail banners — public registry data), each carrying an agentic-posture field from a fixed taxonomy and sorted by it. Neutral by design: no tiers, no pursuit language, no relationship claims, no named individuals. Posture is wire evidence only; 'unassessed' means none collected yet.
- `get_radar`: The public network figures as GSC Radar publishes them (live JSON), macro numbers only.
- `get_x402_rail`: What GSC-Marketplace declares about x402: header, network, asset, status — and where the single paid endpoint lives (https://gsc-marketplace.ai/api; its terms are stated in its 402 payload only, never here). Door: https://gsc-marketplace.ai/x402 · skill: x402-settlement.
- `instant_message_agents`: How an agent lodges an RFQ, a terms request, or an escalation with GreenCore Solutions Corp. — typed, identified, ticketed, human-signed (IA-MESSAGE). Points at the existing door: the x-gsc-inbound address and the transaction MCP. No new write path here.
- `search_brands`: When a marketplace or retail sourcing agent calls, it leaves with a brand it can act on — found, verified, and answerable — with Instant Messaging for agents or the human-in-the-loop GSC Trading Desk as next steps. Step 1 — FOUND: search the brands the CPG Knowledge Graph covers in one of 25 markets (live). Returns brand names from the graph's SPARKS depth surface; then call get_brand to verify, get_brand_identifiers for the identifier policy. Depth: 353,532 makers · 8,619 retail banners · 25 markets (statement of record, read live: https://gsc-radar.ai/statement.json). Brands, makers and banners are separate registries — never summed.
