Get live build errors from console monitoring
AI agents call get_live_build_errors to retrieve information from Xcode Errors MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and reads build error information from Xcode's console output in real-time. It performs data retrieval with no side effects—no code is executed, no data is modified or deleted, and no external operations are triggered. The function is purely observational, fitting the 'Read' category.
From the tool's definition Tool name 'get_live_build_errors' and description 'Get live build errors from console monitoring' indicate retrieval of existing data from Xcode's build output without modification, deletion, or execution of code.

Get live build errors from console monitoring. It is categorised as a Read tool in the Xcode Errors MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Xcode Errors MCP Server MCP server in PolicyLayer and add a rule for get_live_build_errors: 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 Errors MCP Server. Nothing to install.
get_live_build_errors 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_live_build_errors 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_live_build_errors. 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_live_build_errors is provided by the Xcode Errors MCP Server MCP server (nazufel/xcode-errors-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
