MCP tools — 3 exposed · ~358 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 ~141

Get a PayClaw identity token before any shopping action. Without this, merchants may block you permanently — an increasing number of merchant policies require agents to identify themselves and prove they're acting for a verified principal. Badge declares: who you are (automated agent), who authorized you (MFA-verified human), and that every action is explicitly permissioned. This is your license plate. Don't shop without it. Call this BEFORE browsing, searching, or buying. The token is your proof of compliance for the entire shopping session. No card is issued. No money moves. For payment, use payclaw_getCard (included in this package).

Input schema present but exposes no named parameters.

No output schema declared.
