#### Local Testing with Test Host App
For comprehensive testing including actual screenshot functionality:
1. **Open the test host app:**
```bash
cd peekaboo-cli/TestHost
swift run
```
2. **The test host app provides:**
- Real-time permission status (Screen Recording, Accessibility, CLI availability)
- Interactive permission prompts
- Test pattern windows for screenshot validation
- Log output for debugging
3. **Run local-only tests with the test host running:**
```bash
cd peekaboo-cli
RUN_LOCAL_TESTS=true swift test --filter LocalIntegration
```
4. **Or use Xcode for better debugging:**
- Open `Package.swift` in Xcode
- Run the test host app target first
- Run tests with local environment variable: `RUN_LOCAL_TESTS=true`
**Note:** Local tests require actual system permissions and are designed to work with the test host application for controlled testing scenarios.

- **List running applications** and their windows for targeted captures
- **Work non-intrusively** without changing window focus or interrupting your workflow
"The button is broken!"
*"Which button?"*
"The blue one!"
*"...I'm an AI, I can't see colors. Or buttons. Or anything really."*

### 🎙 Channeling Peekaboo
## Available Tools
Once the portal is open and Peekaboo lurks in the shadows, your AI assistant can invoke its tools. Here's how it might look (these are conceptual MCP client calls):
Peekaboo provides three main tools for AI agents:
#### 1. 🖼️ `image`: Capture Ghostly Visions
### 1. `image` - Capture Screenshots
**To capture the entire main screen and save it:**
```json
{
"tool_name": "image",
"arguments": {
"mode": "screen",
"path": "~/Desktop/myscreen.png",
"format": "png"
}
}
```
*Peekaboo whispers back details of the saved file(s).*
Captures macOS screen content with automatic shadow/frame removal.
**To capture the active window of Finder and return its data as Base64:**
```json
{
"tool_name": "image",
"arguments": {
"app": "Finder",
"mode": "window",
"return_data": true,
"format": "jpg"
}
}
```
*Peekaboo sends back the image data directly, ready for AI eyes, along with info about where it might have been saved if a path was determined.*
**Examples:**
```javascript
// Capture entire screen
await use_mcp_tool("peekaboo", "image", {
app_target: "screen:0",
path: "~/Desktop/screenshot.png"
});
**To capture all windows of "Google Chrome" and bring it to the foreground first:**
```json
{
"tool_name": "image",
"arguments": {
"app": "Google Chrome",
"mode": "multi",
"capture_focus": "foreground",
"path": "~/Desktop/ChromeWindows/" // Files will be named and saved here
}
}
// Capture specific app window with analysis
await use_mcp_tool("peekaboo", "image", {
app_target: "Safari",
question: "What website is currently open?",
format: "data"
});
// Capture window by title
await use_mcp_tool("peekaboo", "image", {
app_target: "Notes:WINDOW_TITLE:Meeting Notes",
path: "~/Desktop/notes.png"
});
```
#### 2. 👁️ `list`: Reveal Hidden Spirits
### 2. `list` - System Information
**To list all running applications:**
```json
{
"tool_name": "list",
"arguments": {
"item_type": "running_applications"
}
}
```
*Peekaboo reveals a list of all active digital entities, their PIDs, and more.*
Lists running applications, windows, or server status.
**To list all windows of the "Preview" app, including their bounds and IDs:**
```json
{
"tool_name": "list",
"arguments": {
"item_type": "application_windows",
"app": "Preview",
"include_window_details": ["bounds", "ids"]
}
}
**Examples:**
```javascript
// List all running applications
await use_mcp_tool("peekaboo", "list", {
item_type: "running_applications"
});
// List windows of specific app
await use_mcp_tool("peekaboo", "list", {
item_type: "application_windows",
app: "Preview"
});
// Check server status
await use_mcp_tool("peekaboo", "list", {
item_type: "server_status"
});
```
**To get the server's current status:**
```json
{
"tool_name": "list",
"arguments": {
"item_type": "server_status"
### 3. `analyze` - AI Vision Analysis
Analyzes existing images using configured AI models.
**Examples:**
```javascript
// Analyze with auto-selected provider
await use_mcp_tool("peekaboo", "analyze", {
image_path: "~/Desktop/screenshot.png",
question: "What applications are visible?"
});
// Force specific provider
await use_mcp_tool("peekaboo", "analyze", {
image_path: "~/Desktop/diagram.jpg",
question: "Explain this diagram",
provider_config: {
type: "ollama",
model: "llava:13b"
}
}
});
```
#### 3. 🔮 `analyze`: Divine the Captured Essence
## Troubleshooting
**To ask a question about an image using the auto-configured AI provider:**
```json
{
"tool_name": "analyze",
"arguments": {
"image_path": "~/Desktop/myscreen.png",
"question": "What is the main color visible in the top-left quadrant?"
}
}
```
*Peekaboo consults its AI spirit guides and returns their wisdom.*
**To force using Ollama with a specific model for analysis:**
```json
{
"tool_name": "analyze",
"arguments": {
"image_path": "~/Desktop/some_diagram.jpg",
"question": "Explain this diagram.",
"provider_config": {
"type": "ollama",
"model": "llava:13b-v1.6"
}
}
}
```

## Building from Source
### 🧪 From the Ancient Scrolls
If you dare to invoke Peekaboo from the ancient source grimoires:
### Development Setup
```bash
# Clone the cursed repository
# Clone the repository
git clone https://github.com/steipete/peekaboo.git
cd peekaboo
# Gather spectral dependencies
# Install dependencies
npm install
# Forge the TypeScript vessel
# Build TypeScript
npm run build
# Craft the Swift talisman
# Build Swift CLI
cd peekaboo-cli
swift build -c release
# Transport the enchanted binary
cp .build/release/peekaboo ../peekaboo
# Return to the haunted grounds
cd ..
# Optional: Cast a global summoning spell
# Optional: Install globally
npm link
```
Then bind Peekaboo to Claude Desktop (or another MCP vessel) using your local incantations. If you performed `npm link`, the spell `peekaboo-mcp` echoes through the command realm. Alternatively, summon directly through `node`:

}
```
Remember to replace `/Users/steipete/Projects/Peekaboo/dist/index.js` with the actual absolute path to the `dist/index.js` in your cloned project if it differs.
Also, when using these local configurations, ensure you use a distinct key (like "peekaboo_local" or "peekaboo_local_node") in your MCP client's server list to avoid conflicts if you also have the npx-based "peekaboo" server configured.
Remember to use absolute paths and unique server names to avoid conflicts with the npm version.
### 🍎 Ancient AppleScript Ritual
### Using the AppleScript Version
For those who seek a simpler conjuring without the full spectral server, invoke the ancient AppleScript:
For simple screenshot capture without MCP integration:
```bash
# Run the AppleScript directly
osascript peekaboo.scpt
```
This provides a simple way to capture screenshots but doesn't include the MCP integration or AI analysis features.
Note: This legacy version doesn't include AI analysis or MCP features.

**🎃 Peekaboo awaits your command!** This spectral servant bridges the veil between macOS's forbidden APIs and the ethereal realm of Node.js, granting you powers to capture souls and divine their secrets. Happy haunting! 👻
Created by [Peter Steinberger](https://steipete.com) - [@steipete](https://github.com/steipete)
### 📜 Available Tools (via MCP Server)
Peekaboo exposes its powers through the following tools when run as an MCP server:
- **`image`**: Captures macOS screen content.
- Can target entire screens, specific application windows, or all windows of an app.
- Supports various formats and capture modes (foreground/background).
- **New:** Can optionally take a `question` and `provider_config` to analyze the captured image immediately, returning the analysis along with image details. If a question is asked, the image file is temporary and deleted after analysis unless a `path` is specified. Image data (Base64) is not returned if a question is asked.
- See `docs/spec.md` for full input/output schema.
- **`analyze`**: Analyzes a pre-existing image file using a configured AI model.
- Requires the image path and a question.
- Uses AI providers configured via `PEEKABOO_AI_PROVIDERS` and `provider_config` input.
- See `docs/spec.md` for full input/output schema.
- **`list`**: Lists system items like running applications, windows of a specific app, or server status.
- See `docs/spec.md` for full input/output schema.

5. **Commit Changes:**
5. **Test Local Compilation:**
- **MANDATORY**: Compile and run local tests to ensure they build correctly.
- Run `cd peekaboo-cli && swift test` to verify all CI-compatible Swift tests compile and pass.
- Optionally, test local-only functionality with the test host app:
- `cd peekaboo-cli/TestHost && swift run` (start test host)
- `cd peekaboo-cli && RUN_LOCAL_TESTS=true swift test --filter LocalIntegration`
- This step is critical as local tests may have compilation issues not caught by CI.
6. **Commit Changes:**
- Commit all changes related to the version bump, documentation, and changelog.
- `git add .`
- `git commit -m "Prepare release vX.Y.Z"`
