ios_background_test · LDK MCP Server MCP: Risk & Policy

WHAT IT DOES

What ios_background_test does on LDK MCP Server

AI agents invoke ios_background_test 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 ios_background_test needs a policy

The tool triggers background processing and channel monitoring tests, which involves executing operations against the Lightning node. This goes beyond read-only access as it actively tests/runs background processes. Confidence is moderate because 'test' could be read-only but 'background processing' implies active execution of Lightning wallet operations.

From the tool's definition 'Test Lightning background processing and channel monitoring' — runs a test/execution of background processing
