# MCP Composition Demo - Local Development Stack
#
# Starts:
#   - Redis (session memory and cache)
#   - MCP server (all four sub-servers mounted on port 8000)
#
# Usage:
#   docker-compose up           # start everything
#   docker-compose up redis     # start Redis only
#   docker-compose down         # stop and remove containers
#   docker-compose logs -f mcp  # follow MCP server logs
#
# First time setup:
#   cp .env.example .env
#   Edit .env with your API keys
#   docker-compose up

services:

  # ---------------------------------------------------------------------------
  # Redis
  # Used for session memory and caching by all four MCP sub-servers.
  # Two logical databases:
  #   DB 0: session memory (SESSION_BACKEND=redis)
  #   DB 1: cache (CACHE_BACKEND=redis)
