Verdicts

Coinbase Developer Platform (Agentic Wallet, AgentKit, CDP MCP)

Operator-set max per call and max per session that the agent can't change, set in the wallet UI. AgentKit on npm is 0.10.4 from December 2025, and its fix for a local file read and public upload path is unreleased.

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 Developer Platform (Agentic Wallet, AgentKit, CDP MCP)

  1. Run npx awal@2.12.1 status first and sign in with auth login and auth verify if it fails
  2. Pass --max-amount on every awal x402 pay; 1000000 is $1.00
  3. Send an X-Idempotency-Key on server-wallet writes so a retry can't send twice
  4. Don't register AgentKit's flaunch or zora providers on 0.10.4; they read local files
  5. Give an agent a policy-bound server account or an Agentic Wallet, never a full CDP API key

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

Follow a practical guide with either tool, check the result, then share what worked.
