Resolve a build, download text-like log artifacts, save them under a temporary local directory, and return a compact summary with failed tests, highlights, and saved log paths that local agents can inspect with grep or cat.
AI agents call get_build_logs 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 reads and retrieves build logs from Xcode Cloud, downloads them to a temporary location, and returns summary data. It has no side effects on the CI/CD system, does not execute code or scripts, does not modify build configurations, and does not delete or overwrite data. This is a pure read operation with minimal risk if misused by an AI agent—an agent could only access/view logs it has authorization for.
From the tool's definition Tool performs only retrieval actions: 'download text-like log artifacts', 'save them under a temporary local directory', and 'return a compact summary'. No mutation, deletion, execution, or financial operations are described.
Attacks that exploit this kind of access
Resolve a build, download text-like log artifacts, save them under a temporary local directory, and return a compact summary with failed tests, highlights, and saved log paths that local agents can inspect with grep or cat. 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_build_logs: 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_build_logs 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_build_logs 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_build_logs. 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_build_logs 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.
