# Runs the tdmcp MCP server in a container over the HTTP transport.
#
# NOTE: TouchDesigner is NOT containerized — it runs natively on the host
# (the TD Web Server DAT bridge listens on 127.0.0.1:9980 there). The container
# reaches it via `host.docker.internal`, which the extra_hosts mapping below
# resolves to the host gateway (required on Linux; a no-op on Docker Desktop).
