B2B AI FINOPS & WORKFLOW ARCHITECTURE LAB
Full-Stack AI & Workflow True-Cost Calculator
Stop guessing your production AI burn rate with simplistic token sliders. Model the complete 4-Layer B2B AI Stack:
(1) Orchestration Iterator Loops (n8n / Make / Zapier),
(2) Multi-Turn Agent & Hidden MCP Schema Overhead (Claude 3.7 / GPT-4o / DeepSeek / Gemini 2.5),
(3) Unbundled Voice AI (Retell / Vapi / Bland), and
(4) Scraping & Vector DB RAM (Firecrawl / Jina / pgvector).
BENCHMARK HIGHLIGHT: THE ITERATOR & MCP SCHEMA DOUBLE-TAX
At 10,000 monthly runs, a workflow passing a 25-item array through 4 loop modules costs $1,111.95/mo on Make.com vs $60.00/mo on n8n Cloud Pro ($14.50/mo Self-Hosted). Meanwhile, attaching 15 MCP tools to a 5-turn Claude 3.7 Sonnet agent adds 36,000 hidden schema tokens per run ($1,080/mo) unless Prompt Caching breakpoints (cache_control) are enabled (-82% cost).

CRITICAL BILLING MECHANIC DETECTED IN THIS STACK
Attaching 15 MCP servers (45 tool schemas) injects ~21,600 hidden input tokens on EVERY agent loop turn. In a 6-step ReAct loop without `cache_control` breakpoints, you pay $0.38 per single user query just for tool schemas!
