List recent build runs for a workflow, optionally filtered by outcome. Automatically paginates through build runs. Use limit to cap the number of results returned.
AI agents call list_build_runs 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.
This tool retrieves and queries build run history from Xcode Cloud workflows without modifying any data. It has no side effects beyond data retrieval. The blast radius of misuse is minimal—an agent could retrieve unnecessary build metadata but cannot trigger builds, delete artifacts, or affect the CI/CD pipeline state.
From the tool's definition Tool lists recent build runs with optional filtering; uses pagination and limit parameters. The verb 'list' and readonly operation on build run metadata (no creation, modification, or deletion of builds).
Attacks that exploit this kind of access
List recent build runs for a workflow, optionally filtered by outcome. Automatically paginates through build runs. Use limit to cap the number of results returned. 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 list_build_runs: 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.
list_build_runs 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 list_build_runs 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 list_build_runs. 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.
list_build_runs 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.
