[Data Quality / Validation] OHLCVローソク足データの品質検証。 分析やバックテスト前に「このデータ信用できる？」を確認するためのツール。 完全性（歯抜け）・重複・OHLCV整合性・価格異常値・出来高異常値を検出し、0-100の品質スコア（A-F）を算出。 ペアの流動性ティア（major/mid/minor）を自動判定し、暗号資産のファットテール分布や低流動性ペアの出来高ゼロを考慮した適切なデフォルト閾値を適用。 閾値は price_sigma, volume_multiplier で手動調整も可能。
AI agents call validate_candle_data to retrieve information from Bitbank without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Even though validate_candle_data only reads data, uncontrolled read access leaks sensitive information and racks up API costs — an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

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