Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • get_x402_rail reads open 8d ago

    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.

  • get_aio_agent_fleet reads open 8d ago

    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_marketplace_operators reads open 8d ago

    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_cpg_knowledge_graph reads open 8d ago

    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_acm_68000 reads open 8d ago

    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_brand_identifiers reads unknown 8d ago

    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.

  • search_brands reads unknown 8d ago

    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.

  • instant_message_agents reads unknown never probed

    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.

  • get_brand reads unknown 8d ago

    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.

  • contact_trading_desk sends messages unknown never probed

    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.

_ try it over mcp through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 46660ac4e2bf58b7.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/46660ac4e2bf58b7/claim. Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we knowoff the mcp door
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.

Served from the same domain, which is what was measured. Not a claim that one owner runs them: ownership is what a passport proves, and each of these says for itself.
