AI agents call xcode_get_code_coverage to retrieve information from Xcode without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves pre-existing test coverage data from a completed test run. It performs no writes, deletions, or executions—only read access to test results. The blast radius of misuse is minimal, as an AI agent could only gain visibility into test coverage metrics, which is informational only.
From the tool's definition The tool name and description indicate a retrieval operation: 'Get code coverage report from latest test run' queries and returns test metrics without modifying any data or executing new operations.
Attacks that exploit this kind of access
Get code coverage report from latest test run. It is categorised as a Read tool in the Xcode MCP Server, which means it retrieves data without modifying state.
Register the Xcode MCP server in PolicyLayer and add a rule for xcode_get_code_coverage: 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. Nothing to install.
xcode_get_code_coverage 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 xcode_get_code_coverage 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 xcode_get_code_coverage. 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.
xcode_get_code_coverage is provided by the Xcode MCP server (raunaksplanet/xcode-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
