YAML 전략 문자열의 유효성을 검증합니다.
AI agents call validate_yaml_tool to retrieve information from KIS MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Validation tools are purely read-only operations that inspect input without modifying, executing, or deleting anything. Even though the broader server handles financial trading operations, this specific tool is limited to structural validation of YAML content, which poses minimal risk if misused—an attacker could at most validate arbitrary YAML, but cannot execute strategies, move funds, or modify data.
From the tool's definition Tool validates (검증합니다- validates) a YAML strategy string. This is a check/validation operation with no side effects on data or systems. The description indicates it only inspects and reports on YAML structure/syntax validity.
Attacks that exploit this kind of access
YAML 전략 문자열의 유효성을 검증합니다. It is categorised as a Read tool in the KIS MCP Server MCP Server, which means it retrieves data without modifying state.
Register the KIS MCP Server MCP server in PolicyLayer and add a rule for validate_yaml_tool: 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 KIS MCP Server. Nothing to install.
validate_yaml_tool 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_yaml_tool 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_yaml_tool. 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_yaml_tool is provided by the KIS MCP Server MCP server (soyjefu/kis-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
