jint-browser fetch https://example.org/ --dump markdown
jint-browser eval https://example.org/ "document.title"
jint-browser serve --port 9222
jint-browser mcp

The tool is a single .NET process with no browser download. It does not render and cannot produce screenshots, PDFs, or visual layout.

Standard output is the command's answer; page and usage diagnostics go to standard error. This makes fetch and eval safe to pipe. The mcp command reserves standard output for protocol messages.
