Deprecated: no live endpoint. Measured on 2026-09-27 against two public DNS resolvers (8.8.8.8 and 1.1.1.1):
api.certta.com.br, the host this server calls, does not resolve in DNS.docs.certta.airedirects to CAF's documentation (Certta is CAF's current brand), which namesapi.combateafraude.com/v1(Core API, not recommended for new integrations) andapi.us.prd.caf.io(Connect API); this server was not written against either and has not been checked. See also@codespar/mcp-caf. No tool in this server reaches a service. The package is deprecated on npm and stays in this repository for reference only. If you have a working endpoint, point the server at it withCERTTA_BASE_URL. To bring the package back, open an issue in mcp-dev-latam with the provider's documented base URL.
