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_wall open 56m ago

    All 64 cells of the Canvas64 wall, A1 to H8: who owns each (name and wallet), its step, what it was bought for, what buying it out costs now, and the owner's links. Use it to find free cells, the cheapest cell, the priciest cells or a creator on the wall.

    mcp-tool

      "type": "object",
      "properties": {

  • get_rules open 56m ago

    The rules of Canvas64 in a few quotable sentences: the price formula, the payout, the royalty, the contract and network, the services a cell links to, the audit status and the docs.

    {
      "type": "object",

    }
    arguments 5 lines
  • get_cell unknown 56m ago

    One cell by its address (A1 to H8): owner, step, price paid, the price to claim or buy it out now, what the buyer gets when they are bought out in turn, their royalty after that, and the link where a person buys it with their own wallet.

    mcp-tool

    {
      "type": "object",

        }
      },
      "additionalProperties": false
    }
    arguments 14 lines
  • quote unknown never probed

    The Canvas64 price model for one step of any cell: its price, what its owner gets when bought out, their royalty on every later sale, and optionally how much that royalty has paid once the cell reaches a later step. Prices rise 1.65x per step from $30, with no cap.

_ 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 04d92c3536367e9a.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/04d92c3536367e9a/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
80%

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.
