Usage Examples

Real-world scenarios showing how DeepPlan MCP transforms shallow plans into production-ready blueprints.

Example 1: Real-time Chat System

Your draft:

“I want to build a real-time chat app for teams with multiple rooms, file sharing, and typing indicators.”

What you provide to MCP:

  • tech_stack: SvelteKit, Cloudflare Workers, Durable Objects, D1, R2
  • context_constraints: Must run on Cloudflare Edge Runtime

What the Council returns:

  • Use 1 Durable Object per chat room for WebSocket state management
  • Implement WebSocket Hibernation API to reduce idle DO costs by ~80%
  • Store messages in D1 with composite index on (room_id, created_at)
  • Upload files via R2 presigned URLs to bypass the 100MB Worker limit
  • 6 executable next steps with specific file paths

Example 2: E-commerce Marketplace

Your draft:

“Build a multi-vendor marketplace where sellers list products and buyers can purchase with Stripe.”

What the Council catches that you missed:

  • Stripe Connect Express accounts for vendor payouts
  • Inventory race conditions during flash sales (solved with D1 transactions)
  • R2 image optimization pipeline with size variants
  • Webhook idempotency for out-of-order Stripe events

Example 3: IoT Dashboard

Your draft:

“Dashboard showing sensor data in real-time with alerting when values exceed thresholds.”

Council’s key insight:

  • Dual-path data ingestion: Hot path (KV for latest readings, low latency) + Cold path (D1 for historical graphs, batched writes via Queues)
  • Hysteresis alerting: Temperature must exceed threshold for 3 consecutive readings before alerting, preventing alert fatigue

How to Get the Best Results

  1. Be specific about what you’re building — “real-time chat” is better than “an app”
  2. Always include tech_stack — enables stack-specific recommendations
  3. Add constraints — “must run on Edge Runtime” prevents incompatible suggestions
  4. Keep it under 500 words — the Council works best with focused plans
