Full README

Steward x402 Recipe for CrewAI

A CrewAI agent that buys from an x402 pay-per-call rail — real micropayments, real receipts.

The agent connects to @brianbooms/steward-mcp (v0.2.1, 19 tools) over MCP stdio, browses the paid catalog for free, then purchases one weather API call for Austin, TX — $0.01 USDC on Base, signed by your own wallet, verified before signing.

Built by Synthetic Universe LLC. Brian Booms is an AI-assisted artist and content creator.

How payment works

  1. Agent calls steward_purchase_instructions → gets the live 402 quote (price, USDC contract, payee wallet)
  2. Steward MCP verifies scheme, network, payee, and price against your spend caps
  3. Your key signs an EIP-3009 authorization — only for the quoted amount
  4. Rail settles via x402 facilitator; the paid tool returns with a proof-of-payment receipt bound to the on-chain tx

Wrong payee, wrong price, over cap? Refused. No silent spending, ever.

Spend guardrails (enforced server-side, before any signature):

  • STEWARD_MAX_SPEND_USDC=0.05 — hard ceiling per single call
  • STEWARD_MAX_SPEND_DAY_USDC=5.00 — hard ceiling per rolling 24h

Setup

pip install -r requirements.txt

You need two keys:

| Key | For | Required | |---|---|---| | OPENAI_API_KEY (or ANTHROPIC_API_KEY, etc.) | CrewAI's LLM | Yes — CrewAI needs a model | | STEWARD_PAYER_KEY | Your Base wallet private key (0x...), funded with a few USDC | Yes — the MCP server will not start without it (v0.2.1) |

Your key never leaves your machine. It is passed as an environment variable to the local MCP subprocess only — never logged, stored, or transmitted.

Run

STEWARD_PAYER_KEY=0x... OPENAI_API_KEY=sk-... python steward_crewai_recipe.py

The crew runs the free discovery first (catalog browse), then the $0.01 paid weather purchase. Spend ceilings (STEWARD_MAX_SPEND_USDC=0.05, STEWARD_MAX_SPEND_DAY_USDC=5.00) are enforced server-side before any signature.

What the crew does

  1. Scout agent (free): calls steward_catalog, then steward_product for the weather SKU — reports names, SKUs, prices
  2. Buyer agent (paid, $0.01): confirms the price via steward_purchase_instructions, checks it against the $0.05 ceiling, then calls steward_weather for Austin, TX (30.2672, -97.7431) and reports the result + amount paid
