Common questions

Is MCP Certta safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: CERTTA_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed yesterday, and the latest version (0.1.3) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

@codespar/mcp-certta

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.ai redirects to CAF's documentation (Certta is CAF's current brand), which names api.combateafraude.com/v1 (Core API, not recommended for new integrations) and api.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 with CERTTA_BASE_URL. To bring the package back, open an issue in mcp-dev-latam with the provider's documented base URL.

MCP server for Certta — Brazilian identity + signature platform. KYC/KYB (CPF / CNPJ via Receita Federal + SPC / Serasa), face match + liveness, OCR of RG / CNH / comprovantes, antifraud score, ICP-Brasil digital signature + GoCertta electronic signature, and orchestrated onboarding pipelines that chain KYC + biometrics + signature in one process.
