# 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.

### Project discovery

- `discover_projs`
  - Scans a directory (defaults to workspace root) to find Xcode project (.xcodeproj) and workspace (.xcworkspace) files.

  - List Xcode schemes.
- `show_build_settings`
  - Show build settings.
