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).
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 inferenceAPTOS_WALLET_PATH, EVM_WALLET_PATH (or EVM_PRIVATE_KEY) – for payments
Quick-start workflow
get_wallet_addresses() – check what wallets exist.- If empty:
create_aptos_wallet() + create_evm_wallet().
- Fund:
credit_aptos_wallet() + fund_evm_wallet().
- Whitelist addresses at https://arnstein.ch/flow.html.
- Check balances:
balance_aptos(), balance_evm({ chain: "baseSepolia" }).
- Call paid tools:
run_prediction, run_backtest, link_bank_account, or score tools.
Run the skill (demo)
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
