get_kline
AI agents call get_kline to retrieve information from Bitunix MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
K-line data retrieval is a read-only operation that queries historical market prices without modifying positions, executing trades, or moving funds. It has no side effects and poses minimal risk even if called by an AI agent. While the server itself enables financial operations, this specific tool only retrieves reference data.
From the tool's definition Tool name 'get_kline' is a standard financial charting term referring to candlestick (K-line/Kline) historical price data retrieval. No description provided, but the name and context indicate data fetching only.

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