[Flow / CVD / Buy-Sell Pressure] 資金フロー分析（flow / CVD / aggressor ratio / buy-sell pressure）。約定データからCVD・アグレッサー比・スパイクを検出。hours（推奨）で時間範囲指定、または limit で件数指定。
AI agents call get_flow_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 tool performs financial market data analysis and retrieval only. It computes technical indicators (CVD, aggressor ratios, spikes) from historical execution data using time-range or count parameters. No writes, deletions, or financial transactions occur. The tool is analogous to a charting or analytics query—it reads market data and returns calculated metrics.
From the tool's definition Tool analyzes cryptocurrency market flow metrics, CVD (Cumulative Volume Delta), aggressor ratios, and buy-sell pressure from execution data.

Register the Bitbank Lab MCP server in PolicyLayer and add a rule for get_flow_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_flow_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_flow_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_flow_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_flow_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.
