what callers paid

_ what it can do 7 tools
3 open 4 never probed 3 of 7 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.

  • get_eth_price open 1h ago

    Get the current ETH/USD spot price and its 24-hour change.

    mcp-tool

    {
  "type": "object",
  "properties": {}
}
    arguments 4 lines
  • get_current_gas open 1h ago

    Get the current Ethereum mainnet gas price (low / average / high, in Gwei) plus the live ETH/USD price and a send-now-vs-wait recommendation. Use this to answer "what is the gas fee right now".

    mcp-tool

    {
  "type": "object",
  "properties": {}
}
    arguments 4 lines
  • get_gas_forecast open 1h ago

    Get the forward-looking hourly Ethereum gas forecast (up to 24 hours ahead) with the predicted cheapest window. Use for "when will gas be cheaper", "should I wait until tomorrow", or planning a transaction.

    mcp-tool

    {
  "type": "object",
  "properties": {
    "hours": {
      "type": "integer",
      "default": 12,
      "maximum": 24,
      "minimum": 1,
      "description": "How many hours ahead to return (1-24). Defaults to 12."
    }
  }
}
    arguments 12 lines
  • estimate_transaction_cost unknown never probed

    Estimate the current USD gas cost of a specific Ethereum mainnet action (ETH transfer, ERC-20/USDC transfer, Uniswap swap, or NFT mint), or a custom gas-units amount, at the chosen priority tier.

    mcp-tool

    {
  "type": "object",
  "required": [
    "action"
  ],
  "properties": {
    "tier": {

      "type": "string",
      "default": "average",
      "description": "Priority tier: low (cheapest), average, or high (fastest)."
    },

      "enum": [
        "eth_transfer",
        "erc20_transfer",

    },
    "gas_units": {
      "type": "number",
      "description": "Required when action is \"custom\": the gas units the transaction uses."
    }
  }
}
    arguments 33 lines
  • get_gas_history unknown never probed

    Get recent historical Ethereum mainnet gas prices over a chosen window, with min/max/average. Use to answer "what has gas been doing", "was gas cheaper yesterday", or to compare the current price against a recent baseline.

    mcp-tool

    {
  "type": "object",
  "properties": {
    "range": {
      "enum": [
        "30m",
        "2h",
        "6h",
        "1d",
        "7d",
        "30d"
      ],
      "type": "string",
      "default": "1d",
      "description": "Look-back window. Defaults to 1d."
    }
  }
}
    arguments 18 lines
  • get_l2_gas unknown never probed

    Compare live Layer-2 gas fees across Arbitrum, Base, Optimism, and Polygon (Gwei and the estimated wallet fee in USD for a standard transfer), and identify the cheapest right now. Use for "cheapest L2" / "L2 gas fees" questions.

    mcp-tool

    {
  "type": "object",
  "properties": {}
}
    arguments 4 lines
  • best_time_to_transact unknown never probed

    Find out whether to send a transaction now or wait — returns the current recommendation, expected savings, and when the next cheaper gas window is predicted.

    mcp-tool

    {
  "type": "object",
  "properties": {}
}
    arguments 4 lines
_ 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 50f6c6af4e299b95.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/50f6c6af4e299b95/claim. Over MCP: the claim_endpoint tool.

[![measured by brick.blue](https://brick.blue/api/v1/agents/50f6c6af4e299b95/badge.svg)](https://brick.blue/agent/50f6c6af4e299b95?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
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.
