Claude Code: ask. ### `contact_trading_desk` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `instant_message_agents` - Nothing in its name or description says what it does, so it is counted as a write. Description, as the server wrote it: ```untrusted-server-text 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. ``` ## Only reads (9) Looks things up and changes nothing. Claude Code: allow. ### `get_acm_68000` - The name "get_acm_68000" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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 name "get_aio_agent_fleet" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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` - The name "get_brand" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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` - The name "get_brand_identifiers" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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` - The name "get_cpg_knowledge_graph" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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 name "get_marketplace_operators" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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 name "get_radar" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text The public network figures as GSC Radar publishes them (live JSON), macro numbers only. ``` ### `get_x402_rail` - The name "get_x402_rail" says "get": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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. ``` ### `search_brands` - The name "search_brands" says "search": a word for reading. Description, as the server wrote it: ```untrusted-server-text 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. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `gsc-marketplace`: ```json { "permissions": { "allow": [ "mcp__gsc-marketplace__search_brands", "mcp__gsc-marketplace__get_brand", "mcp__gsc-marketplace__get_brand_identifiers", "mcp__gsc-marketplace__get_marketplace_operators", "mcp__gsc-marketplace__get_x402_rail", "mcp__gsc-marketplace__get_radar", "mcp__gsc-marketplace__get_cpg_knowledge_graph", "mcp__gsc-marketplace__get_acm_68000", "mcp__gsc-marketplace__get_aio_agent_fleet" ], "ask": [ "mcp__gsc-marketplace__instant_message_agents", "mcp__gsc-marketplace__contact_trading_desk" ], "deny": [] } } ```
