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.

  • check_service_health open 1h ago

    Read public endpoint availability and current MCP server information. This does not create an order or move funds.

    mcp-tool

    {
  "type": "object",
  "properties": {},
  "additionalProperties": false
}
    arguments 5 lines
  • describe_backlink_service open 1h ago

    Read the verified offer, price, networks, fulfilment model, safety rules, and documentation without creating an order or moving funds.

    mcp-tool

    {
  "type": "object",
  "properties": {},
  "additionalProperties": false
}
    arguments 5 lines
  • get_payment_requirements unknown never probed

    Read supported chains, official USDC contracts, gas assets, exact-price rules, and owner-approval guidance. This never creates an order or signs a transaction.

    mcp-tool

    {
  "type": "object",
  "properties": {
    "network": {
      "enum": [
        "base",

      ],
      "type": "string"
    }
  },
  "additionalProperties": false
}
    arguments 14 lines
  • create_quote unknown never probed

    Create one pending order and return exact USDC payment coordinates. This does not connect a wallet, sign, broadcast, or move funds. Keep the access token secret and obtain the wallet owner's approval before payment.

  • check_payment unknown never probed

    Ask Fresh SEM to look for the exact official-USDC payment from the quoted sending wallet and return the verified order state. This never signs or broadcasts.

    mcp-tool

    {
  "type": "object",
  "required": [
    "order_id",
    "access_token"

    }
  },
  "additionalProperties": false
}
    arguments 21 lines
  • submit_payment_proof unknown never probed

    Submit a transaction hash as a lookup aid. Fresh SEM independently verifies chain, official token, sender, recipient, amount, quote time, success, finality, and single use before fulfilment.

    mcp-tool

    {
  "type": "object",

    "order_id",

      "maxLength": 128,
      "minLength": 32,

      "minLength": 64
    }
  },
  "additionalProperties": false
}
    arguments 27 lines
  • get_order_status unknown never probed

    Return the authorized order state and continue safe payment reconciliation when appropriate. Treat an order as complete only when status is fulfilled.

    mcp-tool

    {
  "type": "object",
  "required": [
    "order_id",
    "access_token"
  ],
  "properties": {
    "order_id": {

      "format": "uuid",
      "description": "Order UUID returned by create_quote."
    },
    "access_token": {
      "type": "string",
      "maxLength": 128,
      "minLength": 32,

_ 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 e227102a60e7808b.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/e227102a60e7808b/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.
