opentabs

Overview

OpenTabs is an MCP server that bridges AI models with real web APIs by leveraging browser sessions. Instead of using screenshots or DOM scraping, it enables authenticated API calls through Chrome extension integration. The platform offers over 100 plugins covering popular services like Slack, Discord, GitHub, Jira, Notion, Figma, AWS, and Stripe, with approximately 2,000 tools available. It features built-in browser tools for screenshots, clicking, typing, and network capture, and allows users to build custom plugins or have the AI discover and build them automatically.
