q2 v0.20.0

Experimental. q2 is under active development and not ready for production use.

Install

curl -fsSL https://raw.githubusercontent.com/quarto-dev/q2/main/install.sh | bash

On Windows (PowerShell):

irm https://raw.githubusercontent.com/quarto-dev/q2/main/install.ps1 | iex

q2 mcp (the Quarto Hub MCP server) needs Node.js 24+ at runtime;
everything else works standalone. Hub connection defaults for quarto-hub.com are built in.

The Linux binaries are statically linked (musl): one build per architecture, no glibc
requirement, works on Alpine and old distros alike. If you specifically need a
dynamically-linked build, install.sh --from-source builds one.

Standalone Quarto Hub MCP server

q2 mcp is also published on its own as a self-contained Node bundle for
running the MCP server without installing q2 — e.g. embedding it in
another tool. Requires Node.js 24+. Download
quarto-hub-mcp-0.20.0.tar.gz, extract, and run node index.mjs --help.
Unlike q2 mcp, this bundle does not embed quarto-hub.com credentials — see
the bundled README.md for the OAuth env vars to set.
(Experimental, temporary channel — npx distribution is planned.)
