AI agents call get_volatility_metrics to retrieve information from Bitbank Lab without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a pure data retrieval and analysis tool. It reads cryptocurrency market data from the bitbank API and computes standard technical analysis metrics (volatility indicators). There are no side effects—no data is created, modified, deleted, or financial transactions initiated. The tool only retrieves and processes existing market data to produce analytical outputs.
From the tool's definition Tool description indicates it 'calculates' (算出) volatility metrics including ATR, realized volatility, Parkinson, Garman-Klass, and Rogers-Satchell indicators from bitbank market data. All sibling tools on this server are analytical functions (analyze_*).

It is categorised as a Read tool in the Bitbank Lab MCP Server, which means it retrieves data without modifying state.
Register the Bitbank Lab MCP server in PolicyLayer and add a rule for get_volatility_metrics: 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 Bitbank Lab. Nothing to install.
get_volatility_metrics 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 get_volatility_metrics 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 get_volatility_metrics. 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.
get_volatility_metrics is provided by the Bitbank Lab MCP server (tjackiet/bitbank-genesis-mcp-server-http-archive). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
