## Verdicts

**Coinbase MCP server (Coinbase for Agents).** Coinbase's remote MCP gives an agent OAuth access to a person's Coinbase account, with ten scopes, per-portfolio grants, revocation from account settings and client order IDs for safe retries. Only allowlisted clients can connect, the tool schemas aren't public, no rate limit is published and no server-side limit on order size is documented.

**Kite Agent Passport.** Spending sessions with per-transaction and total caps, a lifetime and passkey approval are enforced by the service, with step-up checks and an audit log. A person must sign up by email and create a passkey before an agent can pay. No published fee rate, OpenAPI file or Passport status page was found.

## Before you call either

### Coinbase MCP server (Coinbase for Agents)

1. Call `coinbase_portfolios_list` first and name the portfolio on every order; an order without one falls back to the default portfolio and fails if it isn't granted
2. Send a fresh `client_order_id` with each order and reuse it on retry, so a dropped connection doesn't place a second order
3. Preview with `coinbase_orders_preview` and confirm with the person before `coinbase_orders_create`; equity previews may be unavailable
4. Use `ETH-USDC`-style pairs when buying with a USDC balance, and `base_size` in contracts for futures
5. Agree a spending budget before `coinbase_x402_fetch`, set `max_amount`, and keep the `idempotency_key` for any retry; settled payments can't be reversed

### Kite Agent Passport

1. Run `kpass` with `--output json --no-interactive` and branch on the exit code and `error_code`. Exit 6 is a session policy breach, so request a new session rather than logging in again
2. Pass `--idempotency-key` on every `kpass session execute` so a retry after a timeout does not pay twice
3. Ask the person for a session with a small per-transaction cap and a short `--ttl`, and confirm the merchant URL before executing
4. Use `kpass sandbox` test mode and the faucet to try a payment flow without real funds. Scoped cards are not available in sandbox
5. Check the kite-passport skill's trigger rules before installing it, since it directs the agent to paid services ahead of free tools
