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

When this skill is loaded from the autonomous-agent repo, the repo root is the parent of the skill folder {baseDir}. Clone and install from the repo root:

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

Copy .env.example to .env and set:

set X402_FACILITATOR_URL too
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

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/sse/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
