Calculate the Percentage Price Oscillator (PPO) for a given trading pair using Binance OHLCV data
AI agents call calculate_percentage_price_oscillator to retrieve information from Crypto Indicators without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves OHLCV (Open/High/Low/Close/Volume) market data from Binance and computes a technical analysis indicator (PPO). It only reads and calculates — no data is written, modified, or executed. Misuse potential is minimal as it only returns computed indicator values.

Documented attack patterns abuse exactly the kind of access calculate_percentage_price_oscillator gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Crypto Indicators, and nothing reaches the server without passing your rules. This is the rule we recommend for calculate_percentage_price_oscillator:
{
"version": "1",
"default": "deny",
"tools": {
"calculate_percentage_price_oscillator": {}
}
}calculate_percentage_price_oscillator is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Calculate the Percentage Price Oscillator (PPO) for a given trading pair using Binance OHLCV data. It is categorised as a Read tool in the Crypto Indicators MCP Server, which means it retrieves data without modifying state.
Register the Crypto Indicators MCP server in PolicyLayer and add a rule for calculate_percentage_price_oscillator: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Crypto Indicators. Nothing to install.
calculate_percentage_price_oscillator is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the calculate_percentage_price_oscillator rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for calculate_percentage_price_oscillator. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
calculate_percentage_price_oscillator is provided by the Crypto Indicators MCP server (kukapay/crypto-indicators-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Crypto Indicators, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
