# MCP server image for the dev stack.

# Deliberately NOT built on top of jlesage/firefox. That image is Alpine/musl,
# and geckodriver ships only glibc builds -- Mozilla publishes no musl target.
# Running the MCP server in its own glibc container that *joins* Firefox's
# network namespace sidesteps that entirely, and keeps the browser alive across
# server restarts.

# tool call does not block on a GitHub fetch, and the container works offline.
