Loyal Spark MCP server

• activate_loyalty_programFree

  For legacy ERC-20 programs: returns unpauseUtility + enableMinting calldata. For B20 programs: no-op (already active).

• bazaar_discover_mcp_serversFree

  Discover third-party MCP servers published in Coinbase CDP's Bazaar. Read-only. Filter by free-text q and/or network.

• bazaar_discover_resourcesFree

  Discover third-party x402-paid resources published in Coinbase CDP's Bazaar (docs, data feeds, AI inference, etc). Read-only. Filter by free-text q and/or network (e.g. 'base').

• bazaar_pay_and_callwrite actionFree

  Pay and call any x402-paid HTTPS endpoint using the merchant agent's CDP MPC wallet (EIP-3009 exact scheme on Base USDC). Probes the URL for HTTP 402, picks a compatible requirement, signs TransferWithAuthorization via CDP, retries with X-PAYMENT header, and returns the paid response. Requires scope 'mint' and a pre-created CDP wallet. Safety cap: max_usdc (default 0.25, hard limit 10).

• bazaar_probe_x402Free

  GET a candidate x402 URL and, if it responds HTTP 402, return the parsed payment requirements (accepts[]) so the caller can decide whether to pay. HTTPS only. No signing performed.

• cancel_stale_offerswrite actionFree

  Cancel marketplace offers that have been active for more than N days with no completions. Admin-only action tool.

• check_voucher_statusFree

  Check voucher status by code or ID. Public endpoint — no API key or authentication required.

• confirm_mint_feeFree

• create_gift_certificatewrite actionFree

  Create a gift / welcome certificate (UDS-style) with a unique 6-character redemption code (LOYAL-XXXXXX). Customer redeems via QR or by entering the code; merchant then mints tokens on-chain. Use for welcome bonuses, promo campaigns, partnership gifts.

• create_loyalty_programwrite actionFree

  Get factory calldata to deploy a new loyalty token on Base. Defaults to B20 (Base native ERC-20 superset, single tx, active immediately). Pass token_standard='erc20' for the legacy factory. For B20, MINT_ROLE is granted atomically to the merchant admin AND to the agent's CDP wallet (or explicit extra_minters) so autonomous agents can mint with no follow-up transaction.

Unconfirmed fee obligations block future mints.

  Export customer data for a specific loyalty program. Returns wallet addresses, voucher stats, balances, and tier info. Use for analytics, segmentation, and personalized offers.

  After the merchant submits the on-chain mint transaction for a claimed gift certificate, call this to mark it as minted (status pending_mint → redeemed) and store the mint tx hash.

• mint_loyalty_tokensFree

  Record mint intent and get a fee-first `calls[]` bundle: protocol fee mint FIRST, then the recipient mint. The protocol fee is charged in the merchant's own loyalty tokens (not USDC). Submit both calls in order (atomically via EIP-5792 send_calls if your wallet supports it), then call confirm_mint_fee (or POST /agent-api/mint/confirm) with the fee tx hash. Unconfirmed fee obligations block future mints.
