What it can do

Tool names and descriptions exactly as the server reported them on Nov 8, 2026. The maker wrote them, not us; we show them as plain text.

• get_platform_info

  Get info about Loyal Spark protocol on Base L2

• get_my_profile

  Get authenticated agent's profile

• generate_program_defaults

  Workflow planner: field catalog, required parameters, next_actions, and non-binding examples. External agents must choose their own name, symbol, and economics.

• list_loyalty_programs

  List loyalty programs owned by the agent's merchant

• create_loyalty_program

  Get factory calldata to deploy a new loyalty token on Base. Defaults to B20 (Base-native B20 asset standard, ERC-20 compatible, single tx, active immediately). Pass token_standard='erc20' for the legacy factory. For B20, MINT_ROLE is granted atomically to the merchant admin AND t

• register_loyalty_program

  Register a deployed token as a loyalty program in the database. B20 tokens are registered as active; legacy ERC-20 as inactive (activate next).

• activate_loyalty_program

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

• update_program_status

  Update program status in database after onchain activation/pause

• update_program_config

  Update default cashback_rate and/or points_per_dollar for a program (same as merchant dashboard sliders)

• create_reward

  Create a new reward redeemable with loyalty tokens

• mint_loyalty_tokens

• transfer_loyalty_tokens

• earn_points

  Mint cashback tokens for a purchase at the program's cashback rate, optionally redeeming points first (points_to_redeem or redeem_all) to lower the payable amount. Returns a fee-first calls[] bundle (protocol fee mint, then the customer mint): submit in order (atomically via EIP-

• confirm_mint_fee

  Confirm a prepared mint on Base. Verifies the protocol-fee mint and, when recipient_tx_hash is set (or the fee receipt already contains the recipient mint), writes customer_tier_status so get_token_balance leaves 0. Same hash for both fields when EIP-5792 batched the calls. A sec

• list_mints

• create_personalized_offer

• update_reward_status

  Activate or deactivate a reward in the catalog. Use to manage reward availability based on analytics.

• send_report
