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.

Turnkey Agentic Wallets

An agent gets a non-root user that can sign nothing until a policy allows it, with DENY rules taking precedence and human co-approval available. Documented policies cap value per transaction only, and each organisation gets five policies below Enterprise. Signing endpoints returned elevated errors for five hours on 27 August 2026.

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

Turnkey Agentic Wallets

  1. Use a non-root user's key. Refuse root credentials for unattended work, because root bypasses every policy
  2. Scope every signing ALLOW policy by wallet.id or wallet_account.address, or it covers every key the user can reach
  3. Check the activity status on each response. ACTIVITY_STATUS_CONSENSUS_NEEDED means a person must approve within 24 hours
  4. Retry with the identical body to stay idempotent. Changing timestampMs creates a new activity
  5. Back off with jitter on 429 and poll get_activity sparingly, since polling counts against the same 1 to 3 requests a second
