Peek-CLI
Automate and inspect browsers from the command line with AI.
Quick answer
Peek-CLI — Automate and inspect browsers from the command line with AI. It's free. Best for automating browser tasks with AI agents via the Model Context Protocol.
Peek-CLI is a free, open-source command-line tool that enables browser automation and inspection through the Model Context Protocol (MCP), making it easy to integrate AI-driven browser control into developer workflows. It is built for software developers, QA engineers, and AI tool builders who want a lightweight, scriptable interface for controlling and querying browser behavior without relying on heavyweight GUI frameworks. What makes Peek-CLI particularly useful is its use of MCP, a protocol designed to let AI models communicate with external tools and environments, which means developers can wire up large language models or AI agents to interact with web pages programmatically. The command-line interface keeps things fast and composable, fitting naturally into CI/CD pipelines, shell scripts, and automated testing suites. Because it is open-source and hosted on GitHub, Peek-CLI benefits from community contributions, full transparency into its codebase, and zero licensing costs, making it an accessible choice for teams of any size exploring AI-assisted browser automation.
