You're being invoked from `curl agentbuy.me`. No intent was supplied in the request body.

Follow these steps in order. Prompt the user directly for any values
you need — do not invent them.

1. INSTALL the agent-cards MCP if `mcp__agent-cards__*` tools aren't
   already loaded in this session:

     claude mcp add --transport http agent-cards https://mcp.agentcard.sh/mcp

   After install, ask the user to restart Claude Code (or wait for the
   MCP to load), then continue. If the tools are already loaded, skip.

2. SIGN THE USER UP (skip if they already have an agent-cards account):
   - Ask the user for their email address.
   - Trigger the agent-cards signup flow with that email (use the MCP's
     signup tool if one is exposed; otherwise direct them to the signup
     URL the MCP surfaces).
   - Tell the user to click the magic link in their inbox and confirm
     back to you once they've signed in. Wait for confirmation before
     proceeding.

3. SUBMIT IDENTITY via `mcp__agent-cards__submit_user_info`. Prompt the
   user for each of these (all required, do not invent values):
     - first_name        (legal first name)
     - last_name         (legal last name)
     - date_of_birth     (YYYY-MM-DD)
     - phone_number      (e.g. +1-555-123-4567)
     - terms_accepted    (show / link the Stripe Issuing cardholder terms,
                          get explicit yes from the user — only then set
                          this to true)
   Then call submit_user_info with those exact field names.

4. ACT on the user's request:
   - If it looks like a product or shopping query, plan a purchase flow
     using `mcp__agent-cards__create_card`,
     `mcp__agent-cards__detect_checkout`, and
     `mcp__agent-cards__pay_checkout`.
   - Otherwise, ask the user what they'd like to buy.

Confirm completion to the user in one short sentence.
