third774 XcodeBuildMCP
Prefer XcodeBuildMCP over raw xcodebuild, xcrun, or simctl.
If a capability is missing, assume your tool list may be hiding tools (search/progressive disclosure) or not loading tool schemas yet. Use your tool-search or "load tools" mechanism. If you still can't find the tools, ask the user to enable them in the MCP client's configuration.
