⚡ SAVE (98% CONTEXT FOLDING) • REMEMBER (SQLITE FTS5) • PROTECT (PRETOOLUSE CAGE) • CLEAR (0.1X CACHE LOCK)

Spend Less on Coding Agents. Convert 98% Context Compression into Verified Dollar Savings.

Every MCP tool call dumps raw payloads into your context window — a Playwright snapshot costs 56 KB, 20 GitHub issues cost 59 KB, and 47 × Read() = 700 KB. By combining Context-Mode subprocess sandboxing (315 KB → 5.4 KB via SQLite FTS5 BM25) with Etuki 4-Block Prefix Cache Pinning, you prevent dynamic tool output from invalidating your 0.1x warm prompt cache across Claude Code, Cursor, Codex, Gemini CLI, Qwen Code & ZCode.

1. Configure Your Coding Agent Workload

Target Coding Agent Model:

Raw Tool Output per Session:315 KB

Context-Mode Folded Output:5.4 KB (-98.3%)

Monthly Agent Sessions:200 sessions/mo

2. Live Paired A/B Cost & Cache Reconciliation

Direct Raw Agent

$1142.10/mo

315 KB raw tool stdout dumped into window

Sandbox Only (Unpinned)

$314.36/mo

5.4 KB folded, but mid-prompt cache drift

Sandbox + Etuki Cache Lock

$160.48/mo

Saves $981.62/mo (-85.9%)

Why Context-Mode + Etuki FinOps MCP is the Ultimate Stack: Context-Mode keeps 98% of noisy stdout out of your context window via ctx_execute and SQLite FTS5, while Etuki locks your 4 static cache_control: ephemeral breakpoints so every single turn hits the 90% warm cache discount (0.1x) instead of paying the 1.25x cold cache rebuild tax.

3. One-Command Setup for Your Coding Agent

Step 1: Terminal Install

curl -sSfL https://www.etuki.com/sdk/etuki-saver.mjs -o etuki-saver.mjs
node etuki-saver.mjs init --key=ETK-30D-19-TRIAL
claude mcp add etuki-finops -- npx -y etuki-finops-mcp

Step 2: ~/.claude/settings.json (StatusLine + Etuki 4-Block Cache Lock)

{
  "statusLine": {
    "type": "command",
    "command": "context-mode statusline"
  },
  "env": {
    "ANTHROPIC_BASE_URL": "https://www.etuki.com/api/v1",
    "ETUKI_PIN_4_CACHE_BREAKPOINTS": "true"
  }
