What your agent can do

Iugu gives your agent 23 tools it calls directly — pick the ones it needs, in Claude, Cursor, or any MCP client.

  • create_invoice — Create an invoice in iugu (Pix, boleto, or credit card)
  • get_invoice — Get invoice details by ID
  • list_invoices — List invoices with optional filters
Example call
// Your agent calls a tool directly — no glue code.
// CodeSpar's managed tier handles OAuth2, token rotation and rate limits.
const result = await session.call("create_invoice", { /* ... */ });

Install

terminal
$ npm install @codespar/mcp-iugu
