The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

_ what it can do 4 tools
4 never probed 0 of 4 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.

  • corridors reads unknown never probed

    List supported FX corridors, currencies, and liquidity depth.

    mcp-tool

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

    Fetch live reference rates. Pass `pairs` as a comma-separated list, e.g. USDC/BRLA,XSGD/IDRX.

    mcp-tool

    {
  "type": "object",
  "$schema": "http://json-schema.org/draft-07/schema#",
  "properties": {
    "pairs": {
      "type": "string",
      "description": "Comma-separated currency pairs, e.g. \"USDC/BRLA,XSGD/IDRX\""
    }
  },
  "additionalProperties": false
}
    arguments 11 lines
  • fx_quote reads unknown never probed

    Get a live FX quote between any pair of supported stablecoins. Returns amount_out, mid_rate, network_cost, and a quote_id that fx_settle consumes.

    mcp-tool

    {
  "type": "object",
  "$schema": "http://json-schema.org/draft-07/schema#",
  "required": [
    "from_token",
    "to_token",
    "amount"
  ],
  "properties": {
    "amount": {
      "type": "string",
      "description": "Amount in from_token human units"
    },
    "to_token": {
      "type": "string",
      "description": "Destination token / currency code (e.g. IDRX)"
    },
    "from_token": {
      "type": "string",
      "description": "Source token / currency code (e.g. XSGD)"
    }
  },
  "additionalProperties": false
}
    arguments 24 lines
  • fx_settle reads unknown never probed

    Build an unsigned EIP-712 settlement transaction from a quote. Returns typed_data the caller signs in their wallet.

    mcp-tool

    {
  "type": "object",
  "$schema": "http://json-schema.org/draft-07/schema#",
  "required": [
    "quote_id",
    "signer"
  ],
  "properties": {
    "signer": {
      "type": "string",
      "description": "Caller wallet address (0x-prefixed)"
    },
    "quote_id": {
      "type": "string",
      "description": "quote_id returned by fx_quote"
    }
  },
  "additionalProperties": false
}

_ 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.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ 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.
