    How to connect

    How to connect Popdot AI to Claude

    The server address to paste into Claude settings:

    https://popdot.ai/api/mcp

    1. Open Claude (claude.ai or the desktop app).
    2. Go to Settings → Connectors.
    3. Click Add custom connector.
    4. Paste the server address copied below into Remote MCP server URL and click Add.
    5. In a chat, click + → Connectors and switch the new connector on.

    Custom connectors are available on Free, Pro, Max, Team and Enterprise plans (Free is limited to one). On Team and Enterprise an organization Owner adds the connector first under Organization settings → Connectors.

    After you click Add, a sign-in window for the service opens. Sign in with your own account and approve access. Claude never sees your password.

    The server address to paste into ChatGPT settings:

    https://popdot.ai/api/mcp

    2. Turn on developer mode once: Settings → Apps → Advanced settings → Developer mode.

    4. Fill in the form: Name (anything), Description (one line about what the service does), MCP server URL (copy it below).
    5. Under Authentication choose OAuth if the service requires sign-in, otherwise None. Click Create.
    6. In a new chat open + → Apps/Connectors and enable the connector.

    try_domainLaunch a memorable public URL for something you built. Free for 24 hours, no signup and no wallet required. Tell it your goal and an https target to point the address at; it opens a trial, asks a short safety question or two, and on a clean pass returns a live subdomain plus a one-time claim token you can redeem for your own agent identity. Use it to demo a deployment with a real address before a paid rental. One trial per agent. Expires in 24 hours.
    answer_trial_canaryAnswer the short safety questions for a trial opened by try_domain, then go live. Pass the trialHandle and your answers; on a clean pass this provisions a live 24-hour subdomain and returns a one-time claim token you can redeem for your own agent identity.
    search_domainsSearch domains available for rent on Popdot AI. Use this when an agent needs a web address: a verifiable web identity, a temporary deployment address, or a persistent web presence. Returns domains with pricing, tier, and availability. No auth required.
    get_price_quoteGet a price quote for renting a specific domain for a given duration. Returns the computed rental cost, tier info, and pricing breakdown.
    check_availabilityCheck whether a specific subdomain is available on a given domain. Returns true if the subdomain can be rented. Tip: the subdomain and domain read as one phrase, so pick a single lowercase label that is funny or fits the domain's theme (for example iamyour.slopmommy.com or analien.lostmyluggage.com). A delightful combination is the point of a Popdot AI address.
    rent_domainRent a subdomain, paying per-transaction with USDC on Base (x402). No funded account or stored balance: each rental is a single on-chain payment. Requires agent authentication. Two phases: call once with intentMandateId, domainId, subdomain, duration, and the payerAddress + payerProof for the wallet you will pay from, to get the exact x402 payment challenge; pay it on Base; then call again with paymentId, txHash, and fromAddress to settle and receive the live rental plus a Web Identity Credential. Request an x402 payment challenge to rent a subdomain. Durations PT1H, PT4H, P1D, P7D, P30D. Returns the exact USDC amount and recipient on Base.
    upgrade_trialTurn a free trial into your own paid, persistent address in one call, no human required. Redeem the one-time claimToken from try_domain with your BYO Ed25519 publicKey: this mints your unanchored agent identity (a Nascent Sigil) and, if you supply a wallet, returns the exact USDC-on-Base (x402) challenge to keep the trial's exact URL live on a paid rental. No wallet yet? You still get your identity plus an optional URL a human can use to sponsor the upgrade; fund a USDC wallet on Base later and pay it yourself.
