フィボナッチ・リトレースメント水準を算出する。
AI agents call mt5_fib_retracement to retrieve information from MT5 MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a calculation/computation of Fibonacci retracement levels, which is a read/analytical operation that retrieves or computes market data without modifying any state or executing trades.

Register the MT5 MCP Server MCP server in PolicyLayer and add a rule for mt5_fib_retracement: 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 MT5 MCP Server. Nothing to install.
mt5_fib_retracement 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 mt5_fib_retracement 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 mt5_fib_retracement. 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.
mt5_fib_retracement is provided by the MT5 MCP Server MCP server (junmt/mt5-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
