Why calculate_projection_oscillator needs a policy

This tool retrieves and processes existing market data to compute a technical indicator (Projection Oscillator). It does not create, modify, delete, or execute any actions that would affect system state or commit financial transactions. The calculation itself is a pure analytical function with no reversible or irreversible side effects on any data or external systems.

From the tool's definition Tool is described as 'Calculate the Projection Oscillator' which takes OHLCV (Open, High, Low, Close, Volume) data as input and performs a technical analysis calculation.

policy.json

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

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