ios_keychain_test · LDK MCP Server MCP: Risk & Policy

WHAT IT DOES

What ios_keychain_test does on LDK MCP Server

AI agents invoke ios_keychain_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_keychain_test needs a policy

This tool tests/validates keychain storage patterns, which involves executing operations against the iOS Keychain to store or retrieve cryptographic keys. While 'validate' suggests a read-like operation, interacting with the iOS Keychain to test private key storage patterns constitutes execution of security-sensitive operations.

ios_keychain_test Rate-limited

ios_keychain_test stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
