Facturapi gives your agent 20 tools it calls directly — pick the ones it needs, in Claude, Cursor, or any MCP client.
create_invoice — Create a CFDI invoiceget_invoice — Get invoice by IDlist_invoices — List invoices with filters// Your agent calls a tool directly — no glue code.
// CodeSpar's managed tier handles OAuth2, token rotation and rate limits.
