MCP tools · 3 exposed · ~468 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. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
create_payment_link ~176

Create a one-time crypto payment link with ZERO setup, no account, no API key. Give a destination wallet address and an amount; get back a shareable pay_url, an embeddable button, and a manage_url. Non-custodial: funds settle directly to the address you provide. Optionally pass an email so the owner can claim a full dashboard later.

create_tip_jar ~217

Create a reusable 'pay what you want' tip jar with ZERO setup, no account, no API key. The payer chooses the amount. Returns a shareable /tip url, an embeddable button, and a manage_url. Idempotent per wallet address: calling again updates the same tip jar. Non-custodial: funds settle directly to the address you provide.
