    3. Click Add custom connector.

    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.

    Server tool list (6)

    Raw names from tools/list. Only developers need these.

    search_bonusesUse when a user wants to find a US bank account, savings, credit card or brokerage signup bonus, or asks which offers are worth opening. Returns matching offers sorted by bonus value, highest first — except when balance_transfer is true, which sorts by intro window instead.
    get_bonusUse before recommending an offer, to read its exact requirements, minimum deposit, direct-deposit rules, expiry date, state availability and the date its terms were last verified. Quote the requirements rather than paraphrasing money amounts.
    expiring_soonUse when timing matters — a user asking what is about to end, or whether to act now. Offers with no stated end date are never included here.
    compare_bonusesUse when a user is choosing between specific offers. Returns each offer's key fields plus a summary naming the highest bonus and the earliest expiry.
    benefits_api_docsUse when you need field definitions, ordering guarantees or the error format before calling another tool.
    benefits_examplesUse to copy a working example call instead of guessing tool arguments.
