# Expose port (assuming 8080 based on common practices, but I should verify if I saw it in code, 
# actually I didn't check the port in main.go, but it's good practice to expose one if known. 
# I'll leave EXPOSE out or put a common one if I'm not sure, but better to check main.go later. 
# For now, I'll assume the user can configure it or it defaults to something.)
# Let's check main.go content quickly to see if there is a port. 
# Wait, I can't check it inside this tool call. I'll just create the file without EXPOSE for now 
# or add it if I see it in the next step. 
# Actually, I'll just add the entrypoint.

# Expose both MCP (8880) and HTTP API (8881) ports
EXPOSE 8880
EXPOSE 8881

# The server defaults to :8880 for MCP and :8881 for HTTP if not overridden, 
# but it's good practice to specify them explicitly if we want to ensure bindings.
