electron-mcp-server
electron-mcp-server is an MCP (Model Context Protocol) server that automates and observes Electron applications. It can launch Electron apps with debugging enabled, inspect window/target information via Chrome DevTools Protocol, take screenshots via Playwright/CDP, stream Electron logs, build apps, and execute various UI interaction commands (including selector/text-based clicking, form filling, screenshots, and an eval-style command gated by security settings).
Score Breakdown
⚙ Agent Friendliness
🔒 Security
README emphasizes sandboxed execution, input validation/static analysis, encrypted/audited operations, and screenshot encryption (SCREENSHOT_ENCRYPTION_KEY). However, the interface appears to rely mainly on security levels/environment configuration rather than explicit per-user auth/scopes. TLS enforcement and full network exposure model are not described. Dependencies include electron/playwright/ws/zod; no CVE/security posture details are provided in the provided content.
⚡ Reliability
Best When
You control the environment running the MCP server/client, need local automation/observability for Electron apps, and can select an appropriate security level (strict/balanced/permissive/development).
Avoid When
Avoid using permissive/development security levels against untrusted content or third-party Electron apps, and avoid exposing the MCP server to untrusted networks/users.
Use Cases
- • Automated UI workflows for Electron apps (clicking, filling forms, navigation)
- • Visual debugging and state capture via screenshots
- • Inspection of windows/targets and page structure using DevTools Protocol
- • Real-time observability through streaming main/renderer/console logs
- • Development/test automation without modifying the Electron app
- • Cross-platform Electron build automation (via the MCP tool)
Not For
- • Untrusted automation of sensitive apps where granting UI automation is unacceptable
- • Production usage where strict guarantees on resource usage, stability, and audit/retention controls are not defined
- • Public internet exposure without strong network and process isolation
Interface
Authentication
The README emphasizes security levels and sandboxing rather than explicit user authentication/authorization. No OAuth/API key flow is described.
Pricing
Open source (MIT) and distributed via npm/npx; costs are primarily your infrastructure/runtime.
Agent Metadata
Known Gotchas
- ⚠ Incorrect argument structure for send_command_to_electron (e.g., passing a selector string instead of an args object like {"selector": "..."}).
- ⚠ Rapid consecutive clicks can cause timing-related failures ('Click prevented - too soon').
- ⚠ Some commands may be blocked depending on SECURITY_LEVEL.
