[Candles / OHLCV / Candlestick] ローソク足（candles / OHLCV / chart data）を取得。1min〜1monthの各時間足に対応。date は tz（既定 Asia/Tokyo）の暦日として解釈し、その終端以前の limit 本を返す。 詳細は inputSchema を参照。 【重要】バックテストには run_backtest を使用（データ取得〜チャート描画を一括実行）。
AI agents call get_candles 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.
The get_candles tool performs a read-only query of historical cryptocurrency price data (candlestick/OHLCV format). It retrieves information without side effects, modifications, or execution of arbitrary code. The note about using run_backtest for backtesting further confirms this tool is purely for data fetching. No financial transactions, destructive operations, or code execution occur.
From the tool's definition Tool retrieves OHLCV candlestick data ('ローソク足（candles / OHLCV / chart data）を取得'). The description indicates it 'returns' (返す) a limited number of candles based on date and limit parameters, with no modification, deletion, or execution of external operations.

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_candles: 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_candles 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_candles 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_candles. 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_candles 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.
