AgentPay MCP

AgentPay MCP is a stdio Model Context Protocol server for x402 payments and wallet operations. It exposes Agent Wallet SDK functions as MCP tools and loads a caller-controlled signing key from the local process environment.

Variable	Required for wallet tools	Meaning
`AGENT_PRIVATE_KEY`	Yes	Local hot-wallet signing key
`AGENT_WALLET_ADDRESS`	Yes	Deployed `AgentAccountV2` address
`CHAIN_ID`	No	`8453` or `84532`; defaults to Base mainnet
`RPC_URL`	No	Caller-selected Base RPC endpoint
`FACTORY_ADDRESS`	For deployment	Wallet factory address
`NFT_CONTRACT_ADDRESS`	For deployment	Token contract bound to a wallet
`SESSION_TTL_SECONDS`	No	Local session lifetime in seconds

Variable	Default	Meaning
`AGENTPAY_POLICY_DAILY_LIMIT_ETH`	unset	Operator 24-hour rolling limit (ETH-equivalent)
`AGENTPAY_POLICY_PER_TX_CAP_ETH`	unset	Operator per-transaction cap (ETH-equivalent)
`AGENTPAY_POLICY_ALLOWED_RECIPIENTS`	unset	Comma-separated operator recipient allowlist
`AGENTPAY_ALLOW_UNPOLICED_SPEND`	off	`1` permits value movement with no operator policy, relying only on on-chain limits
`AGENTPAY_X402_MAX_PAYMENT`	unset	USDC ceiling applied on top of every per-call x402 cap; non-USDC x402 payments are refused while set
`AGENTPAY_STATE_DIR`	unset	Directory for the fsync'd spend-intent journal; locks and keyed settlements survive restarts, and the journal is compacted to its live state automatically. One process owns the directory at a time (`spend-intents.lock`). If the journal cannot be read or fsync'd, or another live process owns the directory, value movement is refused
`AGENTPAY_ALLOWED_PRIVATE_HOSTS`	unset	Comma-separated hosts whose private address may be reached by outbound requests
`AGENTPAY_ALLOW_PRIVATE_NETWORK`	off	Development only: permit private destinations and plain `http`

Group	Examples
Wallet	`deploy_wallet`, `get_wallet_info`, `queue_approval`
Payments	`send_payment`, `x402_quote`, `x402_pay`, x402 session tools
Policy	`set_spend_policy`, `check_budget`, OTel budget tools
Tokens	Lookup, custom-token registration, balances, and transfers
Execution	Swap, USDC bridge, and mutual-stake escrow
Trust	ERC-8004 identity, reputation, and UAID verification
History	`get_transaction_history` for wallet contract events
