First indexed and scored.

## MCP tools (9)

### `peer_cash_capabilities` (~63 tokens)

Discover Peer Cash capabilities

Return the live Base USDC destination, payout platforms, fiat currencies, payee hints, amount bounds, and pricing model. Call this before naming a rail or currency.

Input parameters:

- `includeRelaySources` (boolean): Include live Relay-supported EVM source chains and tokens

### `peer_cash_estimate` (~84 tokens)

Estimate fiat received

Estimate fiat received for Base USDC at the live Chainlink oracle rate. This is not a locked quote; the binding rate resolves when a buyer fills.

Input parameters:

- `amount` (string, required): Base USDC amount in 6-decimal base units
- `currency` (string, required): Fiat currency from capabilities
- `platform` (string): Optional payout platform for corridor fill timing

### `peer_cash_prepare` (~68 tokens)

Prepare a cash-out

Prepare unsigned Base USDC approval and createDeposit transactions. The MCP server never accepts a private key or submits a transaction. Show the plan and obtain explicit approval before host-side signing.

Input parameters:

- `amount` (string, required): Base USDC amount in 6-decimal base units
- `receive` (required)

### `peer_cash_finalize` (~49 tokens)

Finalize a confirmed cash-out deposit

Read a confirmed Base createDeposit receipt and resolve the resumable Peer deposit id. Call only after the host confirms the createDeposit transaction returned by peer_cash_prepare.

Input parameters:

- `transactionHash` (string, required)

### `peer_cash_prepare_access_policy` (~56 tokens)

Prepare an order access policy

Prepare the unsigned verified-buyer access-policy transaction required for Venmo, Cash App, or PayPal orders. Use only after finalization when peer_cash_prepare returned accessPolicyRequired=true.

Input parameters:

- `depositId` (string, required)

### `peer_cash_order` (~57 tokens)

Read a Peer Cash order

Return one order state, amounts, fills, and next actions from its deposit id. Brief ORDER_NOT_FOUND responses after finalization may be indexer lag; retry this read, never the deposit transaction.

Input parameters:

- `depositId` (string, required)

### `peer_cash_orders` (~48 tokens)

List Peer Cash orders

List orders owned by a maker wallet, optionally limited to orders that still need attention.

Input parameters:

- `inFlight` (boolean)
- `limit` (integer)
- `owner` (string, required)

### `peer_cash_prepare_withdraw` (~55 tokens)

Prepare an order withdrawal

Prepare unsigned transactions to withdraw unmatched funds. Omit amount to close the order; pass a Base USDC base-unit amount for a partial withdrawal.

Input parameters:

- `amount` (string)
- `depositId` (string, required)

### `peer_cash_prepare_top_up` (~43 tokens)

Prepare an order top-up

Prepare unsigned approval and addFunds transactions to add Base USDC to a live order.

Input parameters:

- `amount` (string, required)
- `depositId` (string, required)
