Brazil's largest card acquirer — authorization, capture, boleto, and recurrent payments on Cielo's rails. For enterprise orchestration, tokenization vault, and marketplace onboarding, use Braspag (Cielo's orchestration arm) separately.
Cielo Acquirer gives your agent 22 tools it calls directly — pick the ones it needs, in Claude, Cursor, or any MCP client.

// CodeSpar's managed tier handles OAuth2, token rotation and rate limits.
