Unblink MCP Server

unblink turns any web page into clean, token-budgeted Markdown for an AI agent - with no browser to install. It's a pure-Go MCP server: no Chromium, no V8, no Node, no cgo. It fetches a page, parses HTML5, optionally runs the page's JavaScript against a hand-rolled DOM, throws away everything that exists only for human eyes - nav, ads, chrome, tracking - and hands the model clean Markdown under a token budget, over…. Its 18 documented tools cluster into read & search, browse, links, forms.

People who need browser automation tools inside Claude, Cursor, VS Code, or another MCP client. The project is written in Go.
