Pagerunner — The Browser Layer That Learns

Pagerunner is an open-source Model Context Protocol (MCP) server that acts as a browser automation layer for Chrome. It allows AI agents such as Claude (and any client that supports MCP) to interact with a live Chrome session using your existing browser profiles—including access to cookies, saved passwords, and browsing history. Pagerunner provides a comprehensive automation and scripting toolkit, including navigation, page interactions (click, type, fill, scroll), screenshots, JavaScript execution, tab management, data extraction, and session state management, all controllable via the MCP protocol. Site intelligence features allow agents to adapt by registering JS adapters, reusing site authentication, and automating workflows securely across web environments. Pagerunner is ideal for AI/agent developers, automation engineers, and power users who want to create intelligent, context-aware browser automations integrated with real user data.
