Snowfort Circuit MCP - Computer use for webapps and electron apps
Circuit MCP MCP server exists for a simple reason — assistants are far more useful when they can act on Circuit MCP directly instead of describing what you should do. Snowfort Circuit MCP - Computer use for webapps and electron apps.
Circuit MCP is a comprehensive Model Context Protocol (MCP) server suite that enables AI coding agents to automate both web browsers and Electron desktop applications with unparalleled precision and flexibility.
Once Circuit MCP is connected, these are the calls the assistant has available:
Cross — Browser Support**: Chromium, Firefox, WebKitNavigation — History control, page reload, URL navigationMulti — Window Management**: Control multiple app windows simultaneouslyAccessibility-First — Built-in accessibility tree navigation with element refsbrowser_launch — Launch browser with AI optimizationsbrowser_navigate — Navigate to URL (includes auto-snapshot)browser_resize — Resize browser viewportbrowser_handle_dialog — Set dialog auto-responsebrowser_tab_new — Create new browser tabbrowser_tab_list — List all open tabsbrowser_tab_select — Switch to specific tabbrowser_tab_close — Close specific tab@snowfort/circuit-web on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.
Plenty of browser automation servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Circuit MCP's toolset — Cross, Navigation, Multi and 11 more — is a fair guide to whether it matches your workflow. It is maintained by snowfort-ai; worth a glance at recent repository activity before you build anything load-bearing on it.
