## Which one, for what

### Coinbase MCP server (Coinbase for Agents) (C)

Good for: An agent acting in a person's own Coinbase account, trading spot crypto, US futures and eligible US stocks and paying for market research by x402.

Ahead on:
- Reliability, 55 against 40
- Payments & pricing, 40 against 30
- Maintenance & community, 58 against 48
- Transparency & trust, 64 against 47

Also in its favour:
- No incidents deducted, where Agent Vault by Self loses 4 points for them

Watch for: Only clients Coinbase has allowlisted can connect; other agents need the local CLI and a CDP API key

### Agent Vault by Self (D)

Good for: A person or developer who wants an agent to buy and sign in on ordinary websites with the holder's own card and logins, without the agent seeing them.

Ahead on:
- Schema & documentation, 76 against 65
- Security & auth, 76 against 70

Also in its favour:
- Free to start without a card

Watch for: The home page and launch post say cards are revealed only in an attested enclave. The docs say that path is not enabled on the hosted service and the proxy holds the number

## 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.

**Agent Vault by Self.** Scoped, revocable keys, OAuth on the hosted MCP server, spending caps, approvals and a documented threat model are designed to keep real card numbers and passwords out of the agent's context. The home page and launch post say cards are revealed only in an attested enclave, while the docs say that path is off on the hosted service.

## 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

### Agent Vault by Self

1. Pass the `session` handle from each hosted MCP result on every later call. Without it a page tool is refused or a new signed-out browser opens
2. On a `pending` answer, call `get_pending_result` with its `wait` id in the same turn. Repeating the original call starts a second one
3. Tell the user when `waiting_on_owner` is true. A first fill on a new site waits up to 15 minutes for the holder's approval
4. Before retrying a fill after an unknown outcome, check the merchant's order state or `get_run_report`. Some failures keep a recorded spend
5. Ask the holder to add an agent card to every card the agent may use. A card marked No limits accepts any amount on authorised sites
