Configure the security level and other settings through your MCP client configuration:
VS Code MCP Settings:
{
"mcp": {
"servers": {
"electron": {
"command": "npx",
"args": ["-y", "electron-mcp-server"],
"env": {
"SECURITY_LEVEL": "balanced",
"SCREENSHOT_ENCRYPTION_KEY":"your-32-byte-hex-string"
}
}
}
}
}
Claude Desktop Configuration:
{
"mcpServers": {
"electron": {
"command": "npx",
"args": ["-y", "electron-mcp-server"],
"env": {
"SECURITY_LEVEL": "balanced",
"SCREENSHOT_ENCRYPTION_KEY":"your-32-byte-hex-string"
}
}
}
}
Alternative: Local .env file (for development):
# Create .env file in your project directory
SECURITY_LEVEL=balanced
SCREENSHOT_ENCRYPTION_KEY=your-32-byte-hex-string
Security Level Behaviors:
Level | UI Interactions | DOM Queries | Property Access | Assignments | Function Calls | Risk Threshold |
---|---|---|---|---|---|---|
strict |
❌ Blocked | ❌ Blocked | ✅ Allowed | ❌ Blocked | ❌ None allowed | Low |
balanced |
✅ Allowed | ✅ Allowed | ✅ Allowed | ❌ Blocked | ✅ Safe UI functions | Medium |
permissive |
✅ Allowed | ✅ Allowed | ✅ Allowed | ✅ Allowed | ✅ Extended UI functions | High |
development |
✅ Allowed | ✅ Allowed | ✅ Allowed | ✅ Allowed | ✅ All functions | Critical |
Environment Setup:
- Copy
.env.example
to.env
- Set
SECURITY_LEVEL
to your desired level - Configure other security settings as needed
cp .env.example .env
# Edit .env and set SECURITY_LEVEL=balanced
Instead of raw JavaScript eval, use these secure commands:
// ✅ Secure button clicking
{
"command": "click_by_text",
"args": { "text": "Create New Encyclopedia" }
}
// ✅ Secure element selection
{
"command": "click_by_selector",
"args": { "selector": "button[title='Create']" }
}
// ✅ Secure keyboard shortcuts
{
"command": "send_keyboard_shortcut",
"args": { "text": "Ctrl+N" }
}
// ✅ Secure navigation
{
"command": "navigate_to_hash",
"args": { "text": "create" }
}
See SECURITY_CONFIG.md for detailed security documentation.
The most common mistake when using this MCP server is incorrect argument structure for the send_command_to_electron
tool.
{
"command": "click_by_selector",
"args": "button.submit-btn" // ❌ Raw string - WRONG!
}
{
"command": "click_by_selector",
"args": {
"selector": "button.submit-btn" // ✅ Object with selector property
}
}
Command | Required Args | Example |
---|---|---|
click_by_selector |
{"selector": "css-selector"} |
{"selector": "button.primary"} |
click_by_text |
{"text": "button text"} |
{"text": "Submit"} |
fill_input |
{"value": "text", "selector": "..."} or {"value": "text", "placeholder": "..."} |
{"placeholder": "Enter name", "value": "John"} |
send_keyboard_shortcut |
{"text": "key combination"} |
{"text": "Ctrl+N"} |
eval |
{"code": "javascript"} |
{"code": "document.title"} |
get_title , get_url , get_body_text |
No args needed | {} or omit args |
- Inspect: Start with
get_page_structure
ordebug_elements
- Target: Use specific selectors or text-based targeting
- Interact: Use the appropriate command with correct argument structure
- Verify: Take screenshots or check page state
// Step 1: Understand the page
{
"command": "get_page_structure"
}
// Step 2: Click button using text (most reliable)
{
"command": "click_by_text",
"args": {
"text": "Create New Encyclopedia"
}
}
// Step 3: Fill form field
{
"command": "fill_input",
"args": {
"placeholder": "Enter encyclopedia name",
"value": "AI and Machine Learning"
}
}
// Step 4: Submit with selector
{
"command": "click_by_selector",
"args": {
"selector": "button[type='submit']"
}
}
Error | Cause | Solution |
---|---|---|
"The provided selector is empty" | Passing string instead of object | Use {"selector": "..."} |
"Element not found" | Wrong selector | Use get_page_structure first |
"Command blocked" | Security restriction | Check security level settings |
"Click prevented - too soon" | Rapid consecutive clicks | Wait before retrying |

Electron - Required for running and testing Electron applications
# Install Electron globally (recommended) npm install -g electron # Or install locally in your project npm install electron --save-dev
For the MCP server to work with your Electron application, you need to enable remote debugging. Add this code to your Electron app's main process:
const { app } = require('electron');
const isDev = process.env.NODE_ENV === 'development' || process.argv.includes('--dev');
// Enable remote debugging in development mode
if (isDev) {
app.commandLine.appendSwitch('remote-debugging-port', '9222');
}
Alternative approaches:
# Launch your app with debugging enabled
electron . --remote-debugging-port=9222
# Or via npm script
npm run dev -- --remote-debugging-port=9222
Note: The MCP server automatically scans ports 9222-9225 to detect running Electron applications with remote debugging enabled.
git clone https://github.com/halilural/electron-mcp-server.git
cd electron-mcp-server
npm install
npm run build
# Run tests
npm test
# Development mode with auto-rebuild
npm run dev
The project includes comprehensive test files for React compatibility:
