Resolve a build, ensure logs are materialized locally, and return only the detected failed tests with their assertion messages when available.
AI agents call get_failed_tests to retrieve information from Xcode Cloud without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves and reports test failure data from completed builds. Despite the word 'Resolve' in the description (which could mean 'locate' or 'determine'), the overall function is diagnostic—fetching failed test information for review. No data is created, modified, deleted, or executed as a side effect.
From the tool's definition Tool name is 'get_failed_tests' and description states it 'return[s] only the detected failed tests with their assertion messages.' This is a read-only retrieval operation that queries test results without modifying, deleting, or executing anything.
Attacks that exploit this kind of access
Resolve a build, ensure logs are materialized locally, and return only the detected failed tests with their assertion messages when available. It is categorised as a Read tool in the Xcode Cloud MCP Server, which means it retrieves data without modifying state.
Register the Xcode Cloud MCP server in PolicyLayer and add a rule for get_failed_tests: 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 Xcode Cloud. Nothing to install.
get_failed_tests 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 get_failed_tests 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 get_failed_tests. 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.
get_failed_tests is provided by the Xcode Cloud MCP server (thatfactory/xcode-cloud-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
