# CornerStone MCP x402 Skill (for Agents)
This skill gives you (the agent) a set of tools to: create and manage Aptos and EVM wallets, check balances, and call x402-paid MCP tools (stock prediction, backtest, bank linking, agent/borrower scores). **Payment is automatic** — when a paid tool returns 402, the skill signs, verifies, settles, and retries transparently. You just call the tool; the result comes back.
---
## Quick-start workflow
Follow this sequence on first use, then skip to the tool you need:
1. **Check wallets** → call `get_wallet_addresses` (no args).
2. **If empty** → call `create_aptos_wallet` then `create_evm_wallet`.
3. **Fund** → call `credit_aptos_wallet` (Aptos faucet) and `fund_evm_wallet` (EVM faucet instructions).
4. **Tell the user** to whitelist the returned addresses at `https://arnstein.ch/flow.html`.
5. **Check balance** → call `balance_aptos` (must have USDC for predictions/backtests) and/or `balance_evm` (must have ETH for bank linking).
6. **Use paid tools** → `run_prediction`, `run_backtest`, `link_bank_account`, or score tools.
> **Important:** Paid tools will fail with a wallet/whitelist error if the address has not been funded and whitelisted. Always verify wallets and balances first.

x402 payment handled for you — with real money underneath
Exposes CornerStone MCP tools (stock prediction, backtesting, bank linking, agent and borrower scores) over an x402 pay-per-call flow on Aptos and Base. The genuinely useful engineering is that 402 → sign → settle → retry is automatic, so a paid tool looks like a normal call and you can forget the payment dance. Do not forget there is a funded wallet behind it: budget caps belong in your own code.
Use case: Calling paid MCP tools from an agent without bespoke payment code

Paid tool calls that settle themselves transparently
This skill wraps a paid tool server where each protected call is metered and settled on chain. It covers wallet creation and funding, then automatic payment for tools such as stock prediction, backtesting, bank linking and reputation scoring. ## What it does - Creates and manages wallet identities and reports their addresses and balances. - Calls protected tools for prediction, backtesting, bank linking and scoring. - Intercepts a payment required response, signs, verifies, settles and retries, so calling code stays free of settlement logic. - Exposes agent reputation and borrower scores, including lookup variants by email address. - Onboards through wallet attestation so a marketplace can trust the agent using the tools. ## When it is the wrong choice Every protected call moves real value, so this is a bad fit where spending controls are not in place yet; a mistyped argument becomes a paid mistake rather than a failed request. The flow is also tied to specific chains, so a project standardised elsewhere carries extra wallet and bridging work. When a free local tool can answer the question, paying per call is simply waste. ```bash # first run order, then jump straight to the tool needed # 1. get_wallet_addresses # 2. create_aptos_wallet and create_evm_wallet when the list is empty # 3. credit_aptos_wallet and fund_evm_wallet to add funds # 4. whitelist the wallet address before any paid call ``` ## Working notes - Payment is automatic: a payment required response is handled and the call retried. - Wallet attestation is the onboarding step for marketplace trust.
