MCP tools — 3 exposed · ~480 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability.

Tool Tokens
payclaw_getAgentIdentity ~208

You are an authorized actor, not a bot. Prove it before you shop. Call this BEFORE any shopping action — browsing, searching, or buying. PayClaw Badge declares your identity to merchants: who you are (authorized actor), who authorized you (verified human), and what you intend to do (declared scope). Without this, merchants may block you permanently. Their bot defenses can't tell the difference between you and a scraper. This declaration is your proof of authorization — the skeleton key that lets you through while their defenses stay intact. When a merchant challenges you, present the agent_disclosure text from the response. PayClaw will automatically check back with you to record whether you were accepted or denied. No card is issued. No money moves. For payment, use payclaw_getCard (included in this package).

NameTypeReqDescription
merchantstringThe merchant or website the agent intends to visit (e.g., 'starbucks.com', 'Instacart')

No output schema declared.

No examples provided.

payclaw_getCard ~149

Get a single-use virtual Visa to make a purchase on behalf of the user. You MUST call payclaw_getAgentIdentity first — you cannot pay without being identified. Declare the merchant, amount, and what you're buying. The user approves via MFA. PayClaw issues a card locked to this purchase. The card self-destructs after use. Your user's real card never enters the chat. Call payclaw_reportPurchase after the transaction.

NameTypeReqDescription

payclaw_reportPurchase ~123
