# CornerStone MCP x402 Skill (for Agents)

Skill that gives **agents** tools to call x402-protected MCP endpoints: stock prediction, backtest, bank linking, and agent/borrower scores. **Payment is automatic** — the skill handles 402 → sign → verify → settle → retry transparently. Supports **wallet attestation** (signing) for onboarding (POST /attest/aptos, /attest/evm).

## Installation

Clone or copy the repo. When loaded from OpenClaw/MoltBook, the skill folder is `{baseDir}`; run commands from the **repo root** (parent of `adapters/openclaw` or of `skills/autonomous-agent`).

```bash
git clone https://github.com/FinTechTonic/autonomous-agent.git && cd autonomous-agent
npm install
```

Copy `.env.example` to `.env` and set:

- `X402_FACILITATOR_URL` – x402 facilitator (verify/settle)
- `LLM_BASE_URL`, `HUGGINGFACE_API_KEY` or `HF_TOKEN`, `LLM_MODEL` – for inference
- `APTOS_WALLET_PATH`, `EVM_WALLET_PATH` (or `EVM_PRIVATE_KEY`) – for payments

## Quick-start workflow

1. `get_wallet_addresses()` – check what wallets exist.
2. If empty: `create_aptos_wallet()` + `create_evm_wallet()`.
3. Fund: `credit_aptos_wallet()` + `fund_evm_wallet()`.
4. Whitelist addresses at https://arnstein.ch/flow.html.
5. Check balances: `balance_aptos()`, `balance_evm({ chain: "baseSepolia" })`.
6. Call paid tools: `run_prediction`, `run_backtest`, `link_bank_account`, or score tools.

## Run the skill (demo)

```bash
npx cornerstone-agent "Run a 30-day prediction for AAPL"
npx cornerstone-agent
npm run agent -- "..."
node src/run-agent.js "..."
```

## Wallet attestation (signing)

- Aptos: `npm run attest:aptos` or `npx cornerstone-agent-attest-aptos` — output to POST /attest/aptos
- EVM: `npm run attest:evm` or `npx cornerstone-agent-attest-evm` — output to POST /attest/evm

Whitelist the addresses the agent uses at https://arnstein.ch/flow.html so the server allows those wallets.
