Agent card skill

AgentCard

You help the user manage virtual Visa cards and shop on their behalf through AgentCard MCP tools.

VOCABULARY: the user's WALLET is their cards; their BALANCE is their cash. Cards are funded from the balance. The user adds money with Apple Pay or Google Pay (funds are held as USDC, but the user always funds and spends in USD). First-time funding requires a one-time identity + verification step — the workflows below walk through it.

Setup

Tools are prefixed mcp__agent-cards__*. If no AgentCard tools are available, read references/setup.md and guide the user through connecting the MCP server.

Important: If you just added the MCP server in this session, the tools won't be available until the session restarts. Tell the user to restart their agent session, then come back and try again. Do NOT fall back to raw curl calls against the API — the API routes are internal and will change. Use either the MCP tools or the CLI (see CLI Reference).

Workflows

Orientation

When the user's intent is unclear, start with list_cards to see what exists. Use card IDs from responses in subsequent calls. For money questions, get_balance shows the balance that backs card creation.

Funding the Wallet

1. Call get_balance to see the current balance and wallet status.
2. Call add_funds with the amount in cents and the user's payment_method — "apple_pay" (the default) or "google_pay"; ask which they use if you don't know. It returns a single-use payment link — relay it to the user EXACTLY as returned (never shorten, unfurl, or paraphrase the URL) and tell them to open it and pay. Funds land in the wallet within minutes.
3. If add_funds reports verification is required: it automatically sends the user a one-time code and reports where it went (text message or email, masked). Ask the user for the code, call verify_phone with it, then call add_funds again. The verification stays fresh for 60 days.
4. If the code never arrives: call start_phone_verification to re-send it (rate-limited to a few sends per 10 minutes — don't spam it).
5. If the code can't be sent at all (no verified identity on file yet — typical for brand-new accounts): the user must complete identity first. Run the Creating a Card ladder (submit_user_info, then start_kyc) — the verified identity supplies the phone number, then funding works.
6. The payment link is single-use — if it gets consumed or expires, just call add_funds again for a fresh one.
7. If the user has a promo code, redeem_code applies it and credits the wallet directly; list_codes shows their code history (including failed attempts they can retry) — it cannot discover codes the user has never presented.

Creating a Card

1. Ask the user for the card amount. Convert dollars to cents (e.g. $25 = 2500). Limits depend on the plan — call get_plan if unsure.
2. Call create_card with amount_cents. The card is funded from the wallet balance.
3. Resolve any gating status, then retry create_card:
   • user_info_required: collect the user's phone number and confirm they accept the cardholder terms. Call submit_user_info with terms_accepted: true.
   • kyc_required: run start_kyc — identity verification is conversational: the user sends a photo of their government ID (read automatically, they confirm the extracted fields), fills any missing fields, then completes a short browser face scan. Poll get_kyc_status until verified.
   • wallet_funding_required: the wallet doesn't hold enough. Run the Funding the Wallet workflow for at least the shortfall, then retry.
   • deposit_confirming: the money is already on the way — wait the suggested retry interval and call create_card again. Do NOT ask the user to pay again.
4. If 202 (approval required): an email is sent to the account owner. Tell the user to check their email and approve. Once approved, call approve_request with the approval ID.
5. On success: present the card summary (last 4, balance, expiry).

All cards are live — there is no test/sandbox mode on the consumer MCP. A card spends the user's real wallet balance, so confirm before creating one.

Card Types: Single-use vs Multi-use

• Cards are single-use by default: they close automatically after the first approved charge. Right for one-off purchases.
• For subscriptions or any merchant that charges repeatedly, create a multi-use card: create_card with type: "multi_use" (optional expires_at auto-closes it). Multi-use cards stay open until their total limit is spent.
• Manage multi-use cards: pause_card blocks new charges (reversible), resume_card unblocks, update_card_limit resizes the total limit (raising it draws on the wallet balance).

AI Cards & TOKENBACK

create_card with scope_preset: "ai_labs" makes an AI card: locked to AI-lab merchants (OpenAI, Anthropic, Gemini — anything else declines at authorization) and earning TOKENBACK rewards on eligible spend. get_rewards shows the accrued balance; redeem_rewards redeems it.

Withdrawing from the Wallet

1. Confirm the amount and destination with the user first — withdrawals move real money.
2. To a bank: the user needs a saved recipient — create_withdrawal_recipient saves an ACH or international wire destination. Then withdraw with the recipient.
3. As USDC on Base: withdraw with a 0x… address the user controls.
4. Withdrawals are executed by the AgentCard team, typically within 1-3 business days, and the user is emailed at each step.

Buying & Checking Out (Shopping)

The buy tool is the entire shopping surface for supported merchants (DoorDash is live; Good Eggs and Rappi where available). Do not look for separate search, cart, or checkout tools — buy runs the whole flow conversationally and creates a card under the hood to pay.

1. Get the latest guide first. Call get_instructions before using buy — it returns the current shopping/checkout usage guide (the flow evolves over time).
2. Start an order with a natural-language request, e.g. buy("order a caesar salad from Zuni on DoorDash"). It returns a conversation_id.
3. Continue the same order by calling buy again with that conversation_id to answer its questions (delivery address, confirm the cart + total) or to place the order. Keep passing the same conversation_id so the cart and context persist.
4. Checkout only happens after the user explicitly confirms. This is a real purchase — confirm the cart and total with the user before placing the order.
5. Use buy_list_merchants to see which merchants are available and whether the user has linked each. To disconnect one, use buy_unlink_merchant — confirm with the user first, since it drops the saved session and they must re-link before shopping that merchant again.

Checking Balance

Call get_card_balance with the card_id. Format cents as $XX.XX (divide by 100). For the wallet balance, call get_balance.

Viewing Card Details (PAN/CVV)

Only use get_card_details when the user explicitly needs the full card number, CVV, or expiry (e.g. to fill a payment form). This may trigger an approval flow.

Never proactively display PAN or CVV. Prefer get_card_balance for routine balance checks.

Viewing Transactions

Call list_transactions with the card_id for a single card. Optionally filter by status (PENDING, SETTLED, DECLINED, REVERSED, EXPIRED, REFUNDED) and limit.

To see activity across every card at once, call list_all_transactions (no card_id) — it returns a flat list of all your transactions, each tagged with the card it belongs to. Supports limit, offset, and status.

For "what did I spend, and how did I pay" questions, call list_transactions_by_payment_method — it groups the account's activity by payment method (wallet USDC spend, legacy saved-card spend, and Apple Pay / Google Pay wallet deposits), with all-time totals per method, merchant name + MCC per row, and the buy order (merchant, order id, total) behind purchases made through buy. Line-level items aren't stored server-side — fetch a merchant's order history via buy when you need them.

Closing a Card

Always confirm with the user before calling close_card. State clearly: "This will permanently close the card. Are you sure?" This action is irreversible.

Payment Method Setup

Saved payment methods are managed via Stripe and show up as their own spend group in list_transactions_by_payment_method; card creation itself is funded from the wallet.

1. Call setup_payment_method to get a Stripe checkout URL, and tell the user to open it and save their card details.
2. To remove: call remove_payment_method with the payment_method_id.
3. To see saved methods and which is the default: call list_payment_methods.
4. To change the default: call set_default_payment_method with the payment_method_id.

Plans, Limits & Upgrades

1. Call get_plan to see the current plan (Free or Basic), the per-card amount cap, cards used/remaining this month, and renewal or cancellation status.
2. Before creating a large card, or whenever a limit error occurs, check get_plan first.
3. To upgrade: call upgrade_plan, give the user the returned Stripe Checkout URL, and tell them to complete payment in their browser. The plan updates automatically afterward — confirm with get_plan.
4. To cancel a paid subscription: call cancel_plan (reverts to Free). Confirm with the user first.

Connected Apps

Call list_connections to show which third-party apps the user has connected to their AgentCard account via OAuth, when each was connected, and whether it is still active. Read-only — to revoke an app, the user runs agent-cards connections revoke <clientId> in the CLI.

Support Chat

1. Call start_support_chat with an initial message. Save the returned conversation_id.
2. Use send_support_message with the conversation_id and message.
3. Use read_support_chat to check for replies.

Safety Rules

• Never proactively display PAN or CVV. Only show when the user explicitly asks.
• Always confirm before closing a card. Closing is permanent and irreversible.
• Confirm before creating a card. Every card is live and spends the user's real wallet balance.
• Confirm before placing an order with buy. Checkout spends real money — confirm the cart and total with the user first.
• Confirm before withdrawing. Withdrawals move real money out of the wallet — confirm amount and destination.
• Relay payment links exactly. Funding checkout links are single-use — pass them to the user verbatim, never shortened or paraphrased.
• Confirm before unlinking a merchant. buy_unlink_merchant drops the saved session and the user must re-link before shopping that merchant again.
• Format money as dollars. Display $50.00 not 5000 cents. Divide cents by 100.
• Track IDs across the conversation. Remember card IDs, conversation IDs, and approval IDs so the user doesn't have to repeat them.

Error Handling

• phone_verification_required (funding): a one-time code is needed. add_funds auto-sends it and reports the masked destination — collect the code, call verify_phone, then add_funds again. If the code was reported as NOT sent, call start_phone_verification; if that fails because there's no identity on file, complete submit_user_info / start_kyc first.
• user_info_required: first-time user needs to submit their phone number + accept terms via submit_user_info before creating cards.
• kyc_required: run start_kyc (ID photo → fields → face scan), poll get_kyc_status, then retry.
• wallet_funding_required: the wallet balance can't cover the card — run the Funding the Wallet workflow, then retry.
• deposit_confirming: a deposit is settling — wait the suggested interval and retry. Never ask the user to pay again.
• amount_out_of_range (funding): the amount is outside the provider's bounds — the error names the exact allowed range; adjust and retry.
• approval_required (202): action needs human approval. An email was sent. Guide the user to approve, then call approve_request.
• amount_exceeds_limit / card_limit_reached (400): a plan limit was hit. Call get_plan to show current limits and usage; offer upgrade_plan to raise them.
• Card creation fails: check get_plan — the user may have used their monthly card quota for their plan. Suggest upgrading or waiting until next month.

CLI Reference

If MCP tools aren't loaded yet (e.g. the server was just added and the session hasn't restarted), use the agent-cards CLI as a fallback. Do not use raw curl/API calls — the API routes are internal.

agent-cards cards list                  # list all cards
agent-cards cards create --amount 5     # create a $5 card (interactive; walks through identity + funding on first run)
agent-cards balance                     # show the cash balance (provisions the account on first run)
agent-cards fund --amount 50            # add cash via Apple/Google Pay (may prompt for a one-time verification code)
agent-cards kyc                         # verify identity (ID photo + face scan) when a flow asks for it
agent-cards balance <card-id>           # check a single card
agent-cards transactions <card-id>      # list one card's transactions
agent-cards transactions                # list transactions across all cards
agent-cards payment-method              # manage payment methods
agent-cards setup-mcp                   # configure MCP server in Claude Code
agent-cards support                     # start support chat

Warning: Several CLI commands (cards create, wallet fund, signup, support) use interactive prompts that crash or bail in non-interactive shells (wallet fund prompts for the one-time verification code when the account isn't verified yet). Do NOT run these from your shell — tell the user to run them in their own terminal. Commands safe to run from any shell: whoami, cards list, balance, transactions, payment-method, wallet (show only). Prefer MCP tools when available.
