Newton Browser is a Model Context Protocol (MCP) server: Local-only Chrome and Edge control for MCP clients through an origin-scoped extension. Because it speaks the Model Context Protocol, AI assistants can use Newton Browser as a set of callable tools instead of you copy-pasting between apps.
It runs locally: the npm package newton-browser speaks MCP over stdio on your machine. No credentials are required — it works out of the box. The current release is v0.4.1, published under the MIT license, with source at Koala-Studios/newton-browser on GitHub.
On mcp.site, Newton Browser sits in the Development category. Any MCP client can use it — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed among them — via the install snippets below.
