Calculate the Percentage Volume Oscillator (PVO) for a given trading pair using Binance OHLCV data
AI agents call calculate_percentage_volume_oscillator to retrieve information from BNB Chain MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs financial analysis (PVO calculation) on historical market data but does not modify state, execute transactions, delete data, or commit financial obligations. It retrieves and processes existing OHLCV (Open, High, Low, Close, Volume) data to compute a technical indicator.
From the tool's definition Tool description states 'Calculate the Percentage Volume Oscillator (PVO)' using 'Binance OHLCV data' — this is a data retrieval and technical analysis computation operation with no side effects on blockchain state, wallets, transactions, or storage.
Documented attack patterns abuse exactly the kind of access calculate_percentage_volume_oscillator gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and BNB Chain MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for calculate_percentage_volume_oscillator:
{
"version": "1",
"default": "deny",
"tools": {
"calculate_percentage_volume_oscillator": {}
}
}calculate_percentage_volume_oscillator is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Calculate the Percentage Volume Oscillator (PVO) for a given trading pair using Binance OHLCV data. It is categorised as a Read tool in the BNB Chain MCP MCP Server, which means it retrieves data without modifying state.
Register the BNB Chain MCP server in PolicyLayer and add a rule for calculate_percentage_volume_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 BNB Chain MCP. Nothing to install.
calculate_percentage_volume_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_volume_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_volume_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_volume_oscillator is provided by the BNB Chain MCP server (nirholas/bnbchain-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
