$npm install @agent-exec/mcp-server
Live execution path
Simulate AI Intent → Tenderly → UserOp
One composition for agent spend: challenge, guardrail, simulate, settle.
Step 01
AI Intent
Agent requests paid resource
Step 02
Tenderly Pass
Dry-run clears drain / revert
Step 03
UserOp
Sponsored settle on Base
$ npm install @agent-exec/mcp-server → POST /v1/intent/execute (Tenderly gate) → PAYMENT-REQUIRED → EIP-3009 auth → PAYMENT-RESPONSE → UserOp hash on Base Sepolia
Three core pillars
Everything an agent needs between intent and settlement
x402 Paywalls
HTTP 402 challenges with machine-readable USDC micropayments. Agents attach signed EIP-3009 authorizations — no human checkout.
Session Keys
EIP-7579 scopes with spend caps, contract allowlists, and TTL. Agents transact without holding master keys.
Go Gateway
Sliding-window Redis rate limits and circuit breakers in front of the execution API — protect paymaster float.
Business model
Simple rails pricing
Developer SaaS subscriptions, $0.005 per UserOp, and a 1.5% markup on x402 paywall volume.
