Calculate the On-Balance Volume (OBV) for a given trading pair using Binance OHLCV data
AI agents call calculate_on_balance_volume to retrieve information from Sperax Ecosystem Crypto & DeFI MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only technical analysis calculation on historical price and volume data. It has no side effects—it does not create, modify, delete, or execute transactions. The tool neither moves funds (Financial), runs arbitrary code with variable effects (Execute), nor irreversibly deletes data (Destructive). While it operates in a DeFi context, the tool itself is purely analytical and computational.
From the tool's definition calculate_on_balance_volume calculates OBV using existing OHLCV data from Binance; no modification, deletion, or execution of external operations occurs. It retrieves and processes historical market data for analytical purposes.
Documented attack patterns abuse exactly the kind of access calculate_on_balance_volume gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Sperax Ecosystem Crypto & DeFI MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for calculate_on_balance_volume:
{
"version": "1",
"default": "deny",
"tools": {
"calculate_on_balance_volume": {}
}
} calculate_on_balance_volume 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 On-Balance Volume (OBV) for a given trading pair using Binance OHLCV data. It is categorised as a Read tool in the Sperax Ecosystem Crypto & DeFI MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Sperax Ecosystem Crypto & DeFI MCP Server MCP server in PolicyLayer and add a rule for calculate_on_balance_volume: 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 Sperax Ecosystem Crypto & DeFI MCP Server. Nothing to install.
calculate_on_balance_volume 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_on_balance_volume 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_on_balance_volume. 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_on_balance_volume is provided by the Sperax Ecosystem Crypto & DeFI MCP Server MCP server (sperax/sperax-crypto-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Sperax Ecosystem Crypto & DeFI MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
