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.

Privy Wallets (server wallets, agent wallets, policy engine)

Default-deny policies with DENY precedence on recipients, values, contracts, calldata, typed data and time windows, enforced in AWS Nitro Enclaves. Database problems took API endpoints down for 71 minutes on 18 September 2026, one of 13 incidents since July.

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

Privy Wallets (server wallets, agent wallets, policy engine)

  1. Add a rule for every RPC method the agent needs; a wallet with a policy denies anything unlisted
  2. Pair a rolling cap with a lower per-transaction cap, since aggregations update only after signing
  3. Send an idempotency key on /rpc, /transfer and /wallets calls; reusing one with a changed body returns 400
  4. Set maxValue on the x402 or MPP client for every request
  5. Retry a transaction_broadcast_failure; don't retry a policy_violation
