Get the current version of the Xcode MCP Server.

Returns: The version string of the server

Search for .xcodeproj and .xcworkspace files, optionally including recent projects.

If search_path is empty, searches all paths to which this tool has been granted access. Uses mdfind (Spotlight indexing) to find files efficiently.

Args: search_path: Path to search. If empty, searches all allowed folders. include_recents: If True, include recently opened projects first (default: True) max_search_depth: Maximum directory depth from search path (default: 3) Depth 0 = directly in search path, depth 1 = one level down, etc. regex_filter: Optional regex pattern to filter results max_results: Maximum number of results to return (default: 10)

Returns: A newline-separated list of .xcodeproj and .xcworkspace paths. Recent projects appear first if include_recents=True. Returns empty string if none are found.

Get a visual tree of directories (folders only) in the specified path.

Shows the folder structure as a tree diagram with box-drawing characters. Does not include individual files - use get_directory_listing for file details.

Special behavior: If directory_path ends with .xcodeproj or .xcworkspace, the tree will show the parent directory structure (since these are typically at the root of a project folder).

Args: directory_path: Path to directory to scan. Can also be a .xcodeproj or .xcworkspace path (will scan parent directory in that case). max_depth: Maximum recursion depth (default 4, prevents excessive output). Depth 1 = immediate subdirectories only, Depth 4 = up to 4 levels deep.

Returns: A visual tree representation showing only directories/folders, with a note about using get_directory_listing for file-level details.

Example:
/Users/you/Projects/MyApp/
├── Sources/
│   ├── Models/
│   └── Views/
├── Tests/
└── Resources/

Args: project_path: Path to an Xcode project/workspace directory, which must end in '.xcodeproj' or '.xcworkspace' and must exist.

Returns: A newline-separated list of scheme names, with the active scheme listed first. If no schemes are found, returns an empty string.

Build the specified Xcode project or workspace.

Builds run for up to `timeout` seconds (default 600, i.e. 10 minutes) before
timing out, which guards against a build that hangs indefinitely. Raise it
for large projects whose cold build exceeds the default.

    max_lines: Maximum number of error/warning lines to show (default 25)
    timeout: Maximum seconds to wait for the build to complete. If not
        provided, defaults to 600. Must be a positive integer.

Returns:
    Always returns JSON with format:
    {
        "full_log_path": "~/Library/Caches/xcode-mcp-server/logs/build-{hash}.txt",

        "errors_and_warnings": "Build failed with N errors...

error: ... ..." } The errors_and_warnings field contains a summary message followed by the actual errors/warnings. Errors are prioritized over warnings - errors are shown first, then warnings fill remaining slots.

Run the app and display an alert dialog for you to interact with it.

The app will run in Xcode/Simulator. Once confirmed running, an alert dialog will appear with an "I'm finished - Terminate App" button.

• Click the button when you're done testing → app will be force-stopped

• If the app terminates on its own → no force-stop needed

In either case, runtime logs are extracted and returned after a 2-second wait.

Perfect for: Interactive testing, manual QA, debugging UI flows

Args: project_path: Path to an Xcode project/workspace directory scheme: Optional scheme to run. If not provided, uses the active scheme. regex_filter: Optional regex pattern to find matching lines in the output max_lines: Maximum number of matching lines to return (default 20)

Returns: JSON string with structured console output

Run the app and wait for it to terminate naturally (up to timeout seconds).

The app will run in Xcode/Simulator. If it doesn't terminate within timeout seconds (default 600, i.e. 10 minutes), it will be force-stopped and runtime logs will be extracted.

No user interaction required - fully automated.

Perfect for: Automated tests, CLI tools, apps with defined exit points

Args: project_path: Path to an Xcode project/workspace directory scheme: Optional scheme to run. If not provided, uses the active scheme. regex_filter: Optional regex pattern to find matching lines in the output max_lines: Maximum number of matching lines to return (default 20) timeout: Maximum seconds to wait for the app to terminate before force-stopping it.

Returns: JSON string with structured console output

Launch the app in Xcode and return immediately without waiting.

The app will continue running until you stop it manually in Xcode. No monitoring, no automatic termination, no log extraction.

Use get_runtime_output later (after manual termination) to retrieve logs.

Perfect for: Long-running apps, servers, apps needing extended manual testing

Args: project_path: Path to an Xcode project/workspace directory scheme: Optional scheme to run. If not provided, uses the active scheme.

Returns: Success message indicating the app has been launched

Returns: A formatted list of windows grouped by application, including window IDs that can be used with take_window_screenshot.

Take a screenshot of a window by ID or name (case-insensitive substring match). Window IDs can be obtained by calling list_mac_app_windows, or you can simply pass a partial (or complete) window title, like "News" for the News app. If multiple windows match the provided name, screenshots will be taken for up to the first 5 of them.

Note: Only on-screen windows can be found by name.

Args: window_id_or_name: Window ID number or partial window title to match.

Returns: Path(s) to saved screenshot file(s), one per line if multiple matches.

List all notifications that have been posted since the server started. This is a debugging tool to help understand notification behavior.

Returns: A formatted list of all notifications with timestamps, titles, messages, and subtitles.

Get aggregated build errors and warnings from all builds since the last clean operation.

This tool addresses the issue where incremental builds only show warnings for recompiled files. It parses the build log manifest (LogStoreManifest.plist) and aggregates warnings from all builds since the last clean, excluding warnings from files that were subsequently recompiled.

Strategy:

1. Locate the project's DerivedData/Logs/Build directory

2. Parse LogStoreManifest.plist to find all builds since last clean

3. For each build, parse the .xcactivitylog file to extract:

   • Warnings and errors with file/line/column/message

   • List of files compiled in that build

4. Aggregate warnings, keeping only the most recent warning for each file

5. If a file was recompiled in a later build, use warnings from that later build

This ensures you see all current warnings even after incremental builds.

Args: project_path: Path to an Xcode project or workspace directory max_warnings: Maximum number of warnings to show in response (default 50)

Returns: JSON string with format: { "derived_data_path": "/path/to/DerivedData/...", "summary": { "total_builds": N, "builds_since_clean": M, "builds_analyzed": K, "clean_info": "...", "total_warnings": X, "warnings_by_type": {"warnings": W, "errors": E}, "unique_files_with_warnings": F, "files_recompiled_multiple_times": R }, "aggregated_warnings": [ { "file": "/path/to/File.swift", "line": 123, "column": 45, "message": "...", "type": "warning" } ], "files_with_multiple_builds": [ { "file": "/path/to/File.swift", "builds": 3, "warnings_excluded": 2 } ], "builds_analyzed": [ { "uuid": "...", "title": "Build FunVoice", "time": 782185536.0, "warnings_found": 4, "files_compiled": 26 } ] }

Note: Only the first max_warnings warnings are included in aggregated_warnings.
The summary counts reflect the total before limiting.

Create a new Xcode project with a SwiftUI app template.

Creates a complete, buildable Xcode project with a SwiftUI app entry point, ContentView, and asset catalog. The project uses the modern Xcode 16+ format (objectVersion 77) with automatic file discovery.

Args: parent_directory: Directory where the project folder will be created. Must be within the allowed folders configured for this server. project_name: Name of the project (e.g. "MyApp"). Used for the folder name, target name, and scheme name. platform: Target platform - "ios" or "macos" (case-insensitive). Defaults to "ios". bundle_identifier: Bundle identifier (e.g. "com.mycompany.MyApp"). Defaults to "com.example.{ProjectName}". deployment_target: Minimum deployment target version (e.g. "26.0"). Defaults to "26.0".

Returns: JSON string with project_path, project_directory, platform, bundle_identifier, and files_created.

List available run destinations (devices and simulators) for a project scheme.

Returns destinations filtered to what's compatible with the given scheme. For example, an iOS scheme will show iOS simulators and devices but not Mac destinations (unless the app supports Mac Catalyst).

Use the 'id' field from the results with set_run_destination to change which device Xcode builds and runs for.

Args: project_path: Path to an Xcode project (.xcodeproj) or workspace (.xcworkspace). scheme: Scheme name to list destinations for. If not provided, uses the first scheme found via xcodebuild.

Returns: JSON array of destinations, each with: name, platform, id, and optionally arch, OS, and variant fields.

Set the active run destination (device or simulator) in Xcode.

Use list_run_destinations to get available destination IDs, then pass the desired 'id' value here to select it. Subsequent build and run operations will target this destination.

Args: project_path: Path to an Xcode project (.xcodeproj) or workspace (.xcworkspace). destination_id: The destination identifier to select. This is the 'id' field from list_run_destinations output (e.g. a simulator UDID or device UDID).

Returns: JSON with the name and id of the destination that was set.

Get the currently active run destination for a project.

Returns the device or simulator that Xcode will use for the next build or run operation. This reads from Xcode's workspace state file without opening the project in Xcode.

Note: After calling set_run_destination, Xcode may take several seconds to flush its state to disk. If called immediately after set_run_destination, this may return the previous destination.

Args: project_path: Path to an Xcode project (.xcodeproj) or workspace (.xcworkspace).

Returns: JSON with the active destination's name, platform, architecture, and id. Returns an error message if the active destination cannot be determined (e.g. the project has never been opened in Xcode).
