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.

Tools (exact names + official descriptions)

Session defaults

Before you call any other tools, you must call session_show_defaults to show the current defaults, ensure you then fill in the appropriate missing defaults. You may need to call one or more discovery/list tools to obtain the values needed.

• session_set_defaults
  • Set the session defaults, should be called at least once to set tool defaults.
• session_show_defaults
  • Show session defaults.
• session_clear_defaults
  • Clear session defaults.
