2026 Frontier LLM API Token Economics, Prompt Caching Savings & Autonomous MCP / llms.txt Discovery

Direct Answer • 2026 Agentic Workload FinOps For a production agent handling 10,000 requests/day (8,000 input tokens + 800 output tokens per call), enabling a 75% prompt-cache hit rate cuts monthly spend on GPT-5 from $3,675 to $1,650/mo (55.1% savings) and on Claude 4.5 Sonnet from $7,650 to $2,790/mo (63.5% savings). Replacing raw HTML DOM scraping with compact /llms.txt and JSON-RPC MCP endpoints further reduces input token overhead by 70%–88%.

1. Frontier Model Token Pricing & 30-Day Workload Benchmark (10K Req/Day)

Prices listed per 1,000,000 tokens (USD). Monthly simulation assumes 300,000 calls/month with 8,000 input tokens and 800 output tokens per request:

2. Token Cost Compression via Native /llms.txt & MCP Discovery

Autonomous coding and research agents frequently ingest 45,000–120,000 raw HTML tokens when parsing unoptimized web documentation. Serving concise Markdown specifications at /llms.txt alongside typed JSON-RPC 2.0 tool schemas at /mcp shrinks discovery payloads below 4,000 tokens per lookup:

Monthly_USD = Calls_Mo * (((Input_Tokens * (1 - Cache_Ratio) * Rate_In) + (Input_Tokens * Cache_Ratio * Rate_Cache) + (Output_Tokens * Rate_Out)) / 1,000,000)

Developers can benchmark live MCP tool schemas and verified /llms.txt implementations programmatically through the companion AgentIndex AI & MCP Registry and its zero-dependency Node.js Discovery CLI.
