# Go Micro + MCP Gateway deployment with Docker Compose
#
# This runs:
#   1. Consul     — service registry (discovery)
#   2. App        — your go-micro service(s)
#   3. MCP Gateway — standalone MCP gateway connected to Consul
#   4. Jaeger     — distributed tracing UI
#
# Usage:
#   docker-compose up
#
# Endpoints:
#   MCP Tools:  http://localhost:3001/mcp/tools
#   Consul UI:  http://localhost:8500
#   Jaeger UI:  http://localhost:16686
#   Service:    http://localhost:9090 (RPC)
