Why bsv_toBitcoin needs a policy

The description is empty and the name alone ('bsv_toBitcoin') is ambiguous — it could be a unit conversion, a formatting utility, or something else entirely. Given the server context involves BSV blockchain operations, it might perform a conversion or lookup, but without evidence of financial transactions, I cannot confidently assign a Financial category.

From the tool's definition Tool name 'bsv_toBitcoin' and empty description provide no clear indication of what the tool does.

POLICY

How to control bsv_toBitcoin

PolicyLayer is an MCP gateway — it sits between your AI agents and Bitcoin SV MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for bsv_toBitcoin:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "bsv_toBitcoin": {
      "limits": [
        {
          "counter": "bsv_tobitcoin_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

bsv_toBitcoin gets a rate cap, and everything else on the server is denied unless you say otherwise.
