#### 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.

A ghostly macOS utility that haunts your screen, capturing spectral snapshots and peering into windows with supernatural AI vision. 🎃 Peekaboo is a macOS-only MCP server that enables AI agents to capture screenshots of applications, windows, or the entire system, with optional visual question answering through local or remote AI models.
## 👁️‍🗨️ "I SEE DEAD PIXELS!" - Your AI Assistant, Probably ## What is Peekaboo?
**🎭 Peekaboo: Because even AI needs to see what the hell you're talking about!** Peekaboo bridges the gap between AI assistants and visual content on your screen. Without visual capabilities, AI agents are fundamentally limited when debugging UI issues or understanding what's happening on screen. Peekaboo solves this by giving AI agents the ability to:
Ever tried explaining a UI bug to Claude or Cursor? It's like playing charades with a blindfolded ghost! 👻 - **Capture screenshots** of your entire screen, specific applications, or individual windows
- **Analyze visual content** using AI vision models (both local and cloud-based)
- **List running applications** and their windows for targeted captures
- **Work non-intrusively** without changing window focus or interrupting your workflow
"The button is broken!" ## Key Features
*"Which button?"*
"The blue one!"
*"...I'm an AI, I can't see colors. Or buttons. Or anything really."*
**Enter Peekaboo** - the supernatural sight-giver that grants your AI assistants the mystical power of ACTUAL VISION! - **🚀 Fast & Non-intrusive**: Uses Apple's ScreenCaptureKit for instant captures without focus changes
- **🎯 Smart Window Targeting**: Fuzzy matching finds the right window even with partial names
- **🤖 AI-Powered Analysis**: Ask questions about screenshots using GPT-4o, Claude, or local models
- **🔒 Privacy-First**: Run entirely locally with Ollama, or use cloud providers when needed
- **📦 Easy Installation**: One-click install via Cursor or simple npm/npx commands
- **🛠️ Developer-Friendly**: Clean JSON API, TypeScript support, comprehensive logging
### 🔮 Why Your AI Needs Eyes Read more about the design philosophy and implementation details in the [blog post](https://steipete.com/posts/peekaboo-mcp-screenshots-so-fast-theyre-paranormal/).
- **🐛 Bug Hunting**: "See that weird layout issue?" Now they actually CAN see it! ## Installation
- **📸 Instant Analysis**: Take a screenshot and ask a question about it in one go!
- **🎨 Design Reviews**: Let AI roast your CSS crimes with visual evidence
- **📊 Data Analysis**: "What's in this chart?" AI can now divine the answer
- **🖼️ UI Testing**: Verify your app looks right without the "works on my machine" curse
- **📱 Multi-Screen Sorcery**: Capture any window, any app, any time
- **🤖 Automation Magic**: Let AI see what you see, then fix what you broke
Think of Peekaboo as supernatural contact lenses for your coding assistant. No more explaining where the "Submit" button is for the 47th time! 🙄 ### Requirements

### 🎙 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:** Captures macOS screen content with automatic shadow/frame removal.
```json
{
"tool_name": "image",
"arguments": {
"mode": "screen",
"path": "~/Desktop/myscreen.png",
"format": "png"
}
}
```
*Peekaboo whispers back details of the saved file(s).*
**To capture the active window of Finder and return its data as Base64:** **Examples:**
```json ```javascript
{ // Capture entire screen
"tool_name": "image", await use_mcp_tool("peekaboo", "image", {
"arguments": { app_target: "screen:0",
"app": "Finder", path: "~/Desktop/screenshot.png"
"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.*
**To capture all windows of "Google Chrome" and bring it to the foreground first:** // Capture specific app window with analysis
```json await use_mcp_tool("peekaboo", "image", {
{ app_target: "Safari",
"tool_name": "image", question: "What website is currently open?",
"arguments": { format: "data"
"app": "Google Chrome", });
"mode": "multi",
"capture_focus": "foreground", // Capture window by title
"path": "~/Desktop/ChromeWindows/" // Files will be named and saved here 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:** Lists running applications, windows, or server status.
```json
{
"tool_name": "list",
"arguments": {
"item_type": "running_applications"
}
}
```
*Peekaboo reveals a list of all active digital entities, their PIDs, and more.*
**To list all windows of the "Preview" app, including their bounds and IDs:** **Examples:**
```json
{ ```javascript
"tool_name": "list", // List all running applications
"arguments": { await use_mcp_tool("peekaboo", "list", {
"item_type": "application_windows", item_type: "running_applications"
"app": "Preview", });
"include_window_details": ["bounds", "ids"]
} // 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:** ### 3. `analyze` - AI Vision Analysis
```json
{ Analyzes existing images using configured AI models.
"tool_name": "list",
"arguments": { **Examples:**
"item_type": "server_status"
```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:** ### Common Issues
```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"

## 🧿 Alternative Summoning Rituals ## Building from Source
### 🧪 From the Ancient Scrolls ### Development Setup
If you dare to invoke Peekaboo from the ancient source grimoires:
```bash ```bash
# Clone the cursed repository # Clone the repository
git clone https://github.com/steipete/peekaboo.git git clone https://github.com/steipete/peekaboo.git
cd peekaboo cd peekaboo
# Gather spectral dependencies # Install dependencies
npm install npm install
# Forge the TypeScript vessel # Build TypeScript
npm run build npm run build
# Craft the Swift talisman # Build Swift CLI
cd peekaboo-cli cd peekaboo-cli
swift build -c release swift build -c release
# Transport the enchanted binary
cp .build/release/peekaboo ../peekaboo cp .build/release/peekaboo ../peekaboo
# Return to the haunted grounds
cd .. cd ..
# Optional: Cast a global summoning spell # Optional: Install globally
npm link 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`: ### Local Development Configuration
**Example MCP Client Configuration (using local build):** For development, you can run Peekaboo locally:

``` ```
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. Remember to use absolute paths and unique server names to avoid conflicts with the npm version.
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.
### 🍎 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 ```bash
# Run the AppleScript directly
osascript peekaboo.scpt 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) Read more about Peekaboo's design and implementation in the [blog post](https://steipete.com/posts/peekaboo-mcp-screenshots-so-fast-theyre-paranormal/).
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.
