Dockerfile

# Dockerfile — primarily for the Glama MCP registry (https://glama.ai/mcp/servers).
#
# Builds the MCP server and runs it over stdio. The server starts cleanly
# WITHOUT RetroArch present: the connectivity probe runs in the background
# and the MCP transport comes up immediately, so tools/list responds fast.
# That's exactly what Glama's "start + respond to introspection" check needs.
#
# For actual use you don't need Docker — `npm install -g mcp-retroarch` and
# point it at a running RetroArch with Network Commands enabled. See README.md.
