ldk_test_scenario · LDK MCP Server MCP: Risk & Policy

WHAT IT DOES

What ldk_test_scenario does on LDK MCP Server

AI agents invoke ldk_test_scenario to trigger actions in LDK MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why ldk_test_scenario needs a policy

The tool executes Lightning development scenarios, which likely involves running code paths that interact with Lightning Network operations (channel management, payments, chain sync). 'Run complete scenarios' implies executing multiple operations programmatically. Given the Lightning wallet context, misuse could trigger real financial operations or disrupt channel state, warranting high severity.
