_ what it can do 5 tools
2 open 3 never probed 2 of 5 classified

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.

  • preview_base_usdc open 1h ago

    Free fixed sample of native USDC's on-chain facts on Base. No other token input accepted; does not make a payment.

    mcp-tool

    {
  "type": "object",
  "$schema": "http://json-schema.org/draft-07/schema#",
  "properties": {}
}
    arguments 5 lines
  • get_tool_status open 1h ago

    Read the available tool's Base USDC price, receiver and setup status. Free; configuration does not prove settlement.

    mcp-tool

    {
  "type": "object",
  "$schema": "http://json-schema.org/draft-07/schema#",
  "properties": {}
}
    arguments 5 lines
  • base_token_allowance unknown never probed

    Read an ERC-20 allowance on Base at a pinned block before an AI proposes spending. Returns exact units, decimals and provenance. Does not approve or transfer tokens. Version 253064e6ce6110d8. Requires 0.01 native USDC per call on Base; shared paid pilot limits apply.

    {
  "type": "object",

    },
    "spenderAddress": {
      "$ref": "#/properties/tokenAddress"
    }
  },
  "additionalProperties": false
}
    arguments 22 lines
  • base_token_facts unknown never probed

    Read a Base ERC-20 fact packet at one pinned block: metadata, exact supply, bytecode hash and EIP-1967 implementation slot. Requires 0.01 native USDC on Base; no financial advice.

    mcp-tool

    {
  "type": "object",
  "$schema": "http://json-schema.org/draft-07/schema#",
  "required": [
    "tokenAddress"
  ],

      "description": "ERC-20 contract address on Base mainnet"
    }
  },
  "additionalProperties": false
}
    arguments 15 lines
  • get_runtime_tools unknown never probed

    List mounted tool versions, per-call USDC prices and input schemas. Free. Releases share the receiving wallet and pilot limits, not a universal price.

_ try it 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 0f708e64258a5b45.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/0f708e64258a5b45/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

measured by brick.blue

[![measured by brick.blue](https://brick.blue/api/v1/agents/0f708e64258a5b45/badge.svg)](https://brick.blue/agent/0f708e64258a5b45?ref=badge)

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 know
card completeness
90%

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.
