Electron Debug MCP

Real Chrome DevTools Protocol superpowers for AI coding agents. Give Cursor, Claude & autonomous agents eyes, hands, and deep runtime inspection inside Electron desktop applications.

🌟 Why Electron Debug MCP?

Most AI coding agents struggle with desktop applications: they can edit source code, but they cannot see the resulting window, click buttons, read console errors, or diagnose silent main-process crashes.

Electron Debug MCP bridges your agent directly into your Electron runtime via the Chrome DevTools Protocol (CDP) and Node inspector, unlocking full visual, interactive, and diagnostic autonomy.

✨ Key Superpowers

🛡️ Runtime Security Audit

electron_security_audit evaluates running windows against official Electron security guidelines. Flags nodeIntegration, missing contextIsolation, disabled sandbox, unsafe CSP, missing setWindowOpenHandler, unguarded will-navigate, and executable binary fuses.

🔒 Zero-Leak Secret Automation

Automate logins and API forms without leaking credentials. type_text({ text: "{{secret:VAR}}" }) resolves from process.env and automatically redacts the secret from return values, console logs, network entries, and HAR exports with [REDACTED].

🧩 Autonomous Composite Workflows

High-level single-turn workflows reduce round trips:

act_and_verify: Action → network idle → UI assertion → automatic failure screenshot if assertion fails.
triage: Instant health overview with page state, console errors, network failures, and resolved top exception stack.
network_failure_report: Aggregates failed HTTP calls with response bodies inline plus an exported HAR artifact.

🔌 Deep IPC Observability

ipc_tap: Intercepts main-process ipcMain.handle and webContents.send calls.
ipc_invoke: Call any registered main-process handle channel directly with custom arguments.
ipc_schema_inference: Analyzes traffic patterns and automatically emits inferred TypeScript interfaces for your preload bridge.

🗺️ Source-Mapped Stack Traces

resolve_stack decodes inline base64 and external v3 source maps. When your bundled app throws an exception, the agent gets original .ts and .tsx file names, line numbers, and original source snippets rather than minified bundle noise.

⚡ Frictionless Agent Ergonomics

Optional processId: Automatically defaults to the single active app session.
Tool Annotations: Tools declare standard MCP hints (readOnlyHint, destructiveHint) so clients can auto-approve safe queries.
Artifacts Resource: Output files are indexed as electron://artifact/{id}.

Capabilities & Options

Feature	Syntax / Option	Purpose
Variables & Context	`{{vars.key}}`	Reference values from the script's `vars` object with preserved primitive types (strings, numbers, booleans, objects).
Step Dependencies	`{{steps.id.result.path}}`	Pass outputs, IDs, or tokens computed in earlier steps directly into subsequent tool arguments.
Environment & Secrets	`{{env.KEY}}` · `{{secret:KEY}}`	Inject process environment variables; secrets are automatically masked in logs, console events, and outputs as `[REDACTED]`.
Conditional Branching	`if: "{{steps.check.result.open}} == true"`	Skips step execution unless condition evaluates to true (`==`, `!=`, `<`, `>`, `&&`, `
Expectation Assertions	`expect: { contains, equals, status, js }`	Validates step outcome; custom `js` expressions evaluate against `result` to verify app invariants.
Automatic Retries	`retry: { retries: 3, delayMs: 250 }`	Automatically retries flaky operations with exponential backoff before failing.
Failure Diagnostics	Automated	If a step fails, captures viewport screenshot artifact (`electron://artifact/{id}`), console errors, and network errors.
Playwright Codegen	`exportAs: "playwright"`	Generates a standalone, runnable Playwright `_electron` test script (`.spec.ts`) reflecting the executed sequence.

import { test, expect, _electron as electron } from "@playwright/test";

test("executed script workflow", async () => {
  const electronApp = await electron.launch({ args: ["."] });
  const window = await electronApp.firstWindow();

  // Step: authenticate
  await window.locator("input#token").fill(process.env.APP_API_TOKEN || "");

  // Step: switch_workspace
  await window.locator("button.workspace-switch").click();

  // Step: dismiss_banner
  await window.locator(".promo-modal .close-btn").click();

  // Step: verify_workspace_state
  const evalResult = await window.evaluate("({ active: document.querySelector('#current-ws').textContent.trim(), count: document.querySelectorAll('.item').length })");
  expect(evalResult).toBeDefined();

  await electronApp.close();
});

6. Ref Locators & Set-of-Marks Visual Prompting

Inspect accessibility targets with compact refs (e1, e2) and drive interactions without fragile CSS selectors:

// 1. Take snapshot with Set-of-Marks badges in the screenshot
{ "name": "vision", "arguments": { "markElements": true } }

// 2. Click directly by ref token
{ "name": "click", "arguments": { "ref": "e3" } }

// 3. Type text into ref
{ "name": "type_text", "arguments": { "ref": "e4", "text": "Hello Desktop!" } }

7. Native Electron API Mocking (Dialogs, Shell, Clipboard)

Bypass OS file dialogs, external URL opens, or update checks during automated test runs:

// 1. Mock dialog.showOpenDialog to return test fixtures
{
  "name": "mock_electron_api",
  "arguments": {
    "module": "dialog",
    "method": "showOpenDialog",
    "returns": { "canceled": false, "filePaths": ["/fixtures/document.pdf"] }
  }
}

// 2. Mock shell.openExternal
{

10. Storage State Snapshot & Auth Replay

Save full session state (cookies, localStorage, sessionStorage) into Playwright-compatible storage state artifacts to bypass repeated login flows across tests:

// 1. Export storage state to an artifact
{ "name": "save_storage_state", "arguments": {} }

// 2. Restore state into any new Electron session
{
  "name": "load_storage_state",
  "arguments": {

  }
}

11. One-Shot Bug Repro Bundle & Issue Generator (`repro_bundle`)

      "Remember Me": true
    },
    "submit": true,
    "expect": {
      "textIncludes": "Welcome back"
    }
  }
}

Resolves fields via accessibility tree labels, ARIA attributes, placeholders, or refs (e1), resolves secrets securely, selects dropdown options, toggles checkboxes, clicks submit, and verifies post-submit UI assertions.

13. Network Chaos & Resilience Scorecard (`offline_resilience_check`)

🧯 Troubleshooting

Symptom	Solution
`Electron failed to install correctly`	Run `npm run ensure-electron` to verify and download the platform binary.
`Process not found`	Omit `processId` when debugging a single app; the server resolves it automatically.
Terminal hangs on `node build/index.js`	Normal: the server communicates over stdio JSON-RPC. Spawn it from your MCP client.
Main-process tools fail	Launch the app with `inspectMain: true` to open the Node inspector port.
Port in use / WSAEACCES on Windows	The server dynamically probes and selects ephemeral bindable ports to avoid Hyper-V/WSL conflicts.

📜 Development & Verification

npm test            # Run build, 140 unit tests, and full 111-tool smoke suite
npm run doctor      # Verify environment health and port binding
