SideButton connects AI agents to your browser. It's an open-source browser MCP server that lets Claude, Cursor, and other AI tools interact with any website through your real browser session. WHAT IT DOES SideButton bridges AI and your browser. When connected, AI agents can: • Navigate to any URL • Click buttons and links • Extract text and data from pages • Take screenshots • Scroll and interact with page elements • Capture accessibility snapshots for understanding page structure Everything runs locally through your browser — no cloud proxies, no headless browsers, no credentials shared with third parties. HOW IT WORKS 1. Install the extension 2. Run the SideButton server locally: npx sidebutton 3. The extension connects to the server automatically 4. AI agents (Claude Code, Cursor, Claude Desktop) connect via MCP 5. Your AI agent can now see and control your browser WORKFLOW AUTOMATION SideButton includes a workflow engine that automates multi-step browser tasks using simple YAML definitions: • Browser automation — navigate, click, type, extract data • LLM integration — classify content, generate text, draft replies • Shell commands — run terminal commands as part of workflows • Conditional logic — if/else branching, retry with backoff • Nested workflows — compose complex automations from simple building blocks • Embedded buttons — inject action buttons directly into web pages PRIVACY & SECURITY • 100% local — the server runs on your machine, not in the cloud • No data collection — your browsing data stays on your device • No credentials stored — workflows use your existing browser sessions • Domain policies — workflows can be restricted to specific domains • Open source — full source code available on GitHub (Apache-2.0 license) LINKS • Documentation: https://docs.sidebutton.com • GitHub: https://github.com/sidebutton/sidebutton • Website: https://sidebutton.comSideButton connects AI agents to your browser.
