bsv_toSatoshi · Bitcoin SV MCP Server MCP: Risk & Policy

WHAT IT DOES

What bsv_toSatoshi does on Bitcoin SV MCP Server

AI agents call bsv_toSatoshi to retrieve information from Bitcoin SV MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

THE RISK

Low Risk

Why bsv_toSatoshi needs a policy

Based on naming convention, this appears to be a utility function that converts Bitcoin SV amounts to satoshis—a read-only operation that retrieves or calculates a value without modifying state. The lack of description lowers confidence, but the function name strongly implies a simple conversion/query operation rather than any action that could modify blockchain state or financial transactions.

From the tool's definition Tool name 'bsv_toSatoshi' suggests a unit conversion function (BSV to Satoshi, Bitcoin's smallest unit). No description provided.

POLICY

How to control bsv_toSatoshi

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_toSatoshi:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "bsv_toSatoshi": {}
  }
}

bsv_toSatoshi is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
