DEPRECATED: no live endpoint (api.certta.com.br does not resolve)

Overview

AI-generated overview

Deprecated MCP server for Certta, a Brazilian identity and signature platform; its API host no longer resolves, so no tool reaches a service.

What you can do
  • Look up CPF and CNPJ identity and company data (KYC/KYB)
  • Run face match and passive liveness checks on selfies
  • OCR identity documents such as RG, CNH, CRLV and passports, and score antifraud risk
  • Create ICP-Brasil and electronic signature envelopes and read their status
  • Create and inspect onboarding processes that chain KYC, biometrics and signature
  • Note: the README states no tool in this server reaches a service because the default API host does not resolve.
When to use it
Only as reference material, for example when studying how a Brazilian KYC, biometrics and signature MCP server is structured. It is not suitable for real identity checks or signatures, since the package is deprecated and its endpoint is dead.
Requirements
Runs locally via npx from the npm package @codespar/mcp-certta. Requires the CERTTA_API_KEY environment variable (an API key from the Certta dashboard) and optionally CERTTA_API_BASE to override the base URL. The README also mentions CERTTA_BASE_URL for pointing at a working endpoint, which differs from the declared variable name.
Before you install
The package is deprecated and the default API host does not resolve, so calls will fail. The server handles sensitive personal data (CPF, CNPJ, biometrics, documents) and creates signature envelopes, which are consequential actions if it is ever pointed at a live endpoint. The README's endpoint override name conflicts with the declared CERTTA_API_BASE, so verify configuration before use.

Installation

In SourceWeft

  1. Open Mcp Certta in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

@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.

Score

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
