## MCP tools (18)

### `create_charge` (~199 tokens)

Create a crypto charge — a one-time merchant invoice priced in local fiat that a buyer can settle in BTC, ETH, USDC, and other supported assets. Returns a hosted_url the buyer can be redirected to, plus per-asset payment addresses.

Input parameters:

- `cancel_url` (string): Browser redirect if the buyer abandons the hosted page
- `description` (string, required): Longer human-readable description of what the buyer is paying for
- `local_price` (object): Fiat-denominated price the charge is quoted in. Required when pricing_type is fixed_price.
- `metadata` (object): Arbitrary JSON you want echoed back on events (customer_id, order_id, etc.)
- `name` (string, required): Short product/order name shown on the hosted payment page
- `pricing_type` (string, required): fixed_price: exact amount in local_price. no_price: buyer chooses (donations).
- `redirect_url` (string): Browser redirect after a successful payment

### `retrieve_charge` (~55 tokens)

Retrieve a charge by its Coinbase Commerce id OR its short code (the 8-character code embedded in the hosted URL). Returns current status, timeline, and payments.

Input parameters:

- `code_or_id` (string, required): Charge id or short code

### `list_charges` (~92 tokens)

List charges, newest first. Supports cursor pagination via starting_after / ending_before.

Input parameters:

- `ending_before` (string): Cursor: return results before this charge id
- `limit` (number): Max results per page (default 25, max 100)
- `order` (string): Sort order by created_at. Defaults to desc.
- `starting_after` (string): Cursor: return results after this charge id

### `cancel_charge` (~46 tokens)

Cancel a charge that has not yet been paid. Only charges in NEW status can be cancelled; once pending or completed the call will fail.

Input parameters:

- `code` (string, required): Charge short code

### `resolve_charge` (~48 tokens)

Manually resolve a charge as paid. Used for out-of-band settlement (e.g. underpayment you accept, delayed confirmation you want to honour).

Input parameters:

- `code` (string, required): Charge short code

### `create_checkout` (~126 tokens)

Create a reusable hosted checkout — think product-page-style link that can be paid multiple times. Good for evergreen SKUs and donation pages.

Input parameters:

- `description` (string, required): Longer description shown to buyers
- `local_price` (object): Fiat-denominated price. Required when pricing_type is fixed_price.
- `name` (string, required): Product / checkout name
- `pricing_type` (string, required): fixed_price: exact amount in local_price. no_price: buyer chooses.
- `requested_info` (array): Buyer fields Coinbase should collect on the hosted page (e.g. ["name", "email"])

### `retrieve_checkout` (~23 tokens)

Retrieve a checkout by id.

Input parameters:

- `id` (string, required): Checkout id

### `list_checkouts` (~94 tokens)

List reusable hosted checkouts, newest first. Cursor pagination via starting_after / ending_before.

Input parameters:

- `ending_before` (string): Cursor: return results before this checkout id
- `limit` (number): Max results per page (default 25, max 100)
- `order` (string): Sort order by created_at. Defaults to desc.
- `starting_after` (string): Cursor: return results after this checkout id

### `update_checkout` (~121 tokens)

Update an existing reusable checkout. Supply only the fields you want to change (Coinbase replaces the supplied fields). Use to retitle a product, change the price, or adjust which buyer fields are collected.

Input parameters:

- `description` (string): New checkout description
- `id` (string, required): Checkout id to update
- `local_price` (object): New fiat-denominated price
- `name` (string): New checkout / product name
- `pricing_type` (string): Update pricing model
- `requested_info` (array): New list of buyer fields to collect

### `delete_checkout` (~41 tokens)

Delete a reusable checkout. The hosted URL stops accepting new payments. Existing charges spawned by the checkout are unaffected.

Input parameters:

- `id` (string, required): Checkout id to delete

### `list_events` (~122 tokens)

List events — the lifecycle signals (charge:created, charge:confirmed, charge:failed, charge:delayed, charge:pending, charge:resolved) that Coinbase Commerce also delivers via webhook. Useful for reconciliation and agent polling.

Input parameters:

- `ending_before` (string): Cursor: return results before this event id
- `limit` (number): Max results per page (default 25, max 100)
- `order` (string): Sort order by created_at. Defaults to desc.
- `starting_after` (string): Cursor: return results after this event id

### `retrieve_event` (~59 tokens)

Retrieve a single event by id. Useful when auditing a webhook delivery or replaying state — fetch the event Coinbase Commerce recorded server-side and compare against what your endpoint received.

Input parameters:

- `id` (string, required): Event id (the id field on a webhook payload)

### `create_invoice` (~122 tokens)

Create an invoice — a directed bill sent to a specific named recipient. Unlike a charge, an invoice captures who it was issued to and has its own draft / viewed / paid lifecycle.

Input parameters:

- `business_name` (string, required): Your business name shown on the invoice
- `customer_email` (string, required): Email of the invoice recipient
- `customer_name` (string, required): Display name of the invoice recipient
- `local_price` (object, required): Fiat-denominated amount the invoice is quoted in
- `memo` (string): Free-form note to the recipient (appears on invoice)

### `retrieve_invoice` (~51 tokens)

Retrieve an invoice by code. Returns recipient details, status (DRAFT, OPEN, VIEWED, PAID, VOID), and the linked charge once payment begins.

Input parameters:

- `code` (string, required): Invoice short code

### `list_invoices` (~91 tokens)

List invoices, newest first. Cursor pagination via starting_after / ending_before.

Input parameters:

- `ending_before` (string): Cursor: return results before this invoice id
- `limit` (number): Max results per page (default 25, max 100)
- `order` (string): Sort order by created_at. Defaults to desc.
- `starting_after` (string): Cursor: return results after this invoice id

### `void_invoice` (~48 tokens)

Void an unpaid invoice. The recipient can no longer pay it. Already-paid invoices cannot be voided — refund out-of-band if needed.

Input parameters:

- `code` (string, required): Invoice short code to void

### `list_exchange_rates` (~86 tokens)

Fetch current Coinbase exchange rates for a base asset (e.g. BTC, ETH, USDC) against every supported fiat and crypto. Useful for quoting or reconciling fiat-equivalent amounts. This endpoint is public and does not require the API key.

Input parameters:

- `currency` (string): Base currency code (e.g. BTC, ETH, USDC, USD). Defaults to USD.

### `verify_webhook_signature` (~145 tokens)

Local helper — verify a Coinbase Commerce webhook payload using HMAC-SHA256. Pass the EXACT raw request body string (do not re-stringify the parsed JSON, byte-equivalence matters) and the X-CC-Webhook-Signature header value. The shared secret comes from COINBASE_COMMERCE_WEBHOOK_SECRET unless overridden. Returns { valid: boolean }.

Input parameters:

- `raw_body` (string, required): Exact raw request body bytes as a string
- `secret` (string): Override webhook shared secret. Defaults to COINBASE_COMMERCE_WEBHOOK_SECRET env var.
- `signature` (string, required): X-CC-Webhook-Signature header value (hex)
