Quickstart

Before you use it.

This package is deprecated on npm, so this page offers no install command or client config. No live endpoint: api.certta.com.br does not resolve. See https://github.com/codespar/mcp-dev-latam/tree/main/packages/identity/certta

Environment variables3 variables
CERTTA_API_BASEAPI base URL — defaults to Certta production. Override for sandbox.optional
CERTTA_API_KEYAPI key from the Certta dashboardrequiredsecret
CERTTA_BASE_URLRead by the code; the package manifest does not declare it.

Names read from the package code (@codespar/mcp-certta@0.1.3). Descriptions and flags come from its manifest. Self-hosted, you hold the credentials.

Tools

What your agent can call.

11 tools, as the package's tools/list returns them.

kyc_lookup_cpf

Validate a CPF against Receita Federal + SPC / Serasa. Returns name, DOB, regularity status, restrictions, risk score. POST /v1/kyc/cpf.

kyb_lookup_cnpj

Validate a CNPJ and return company profile — corporate name, fantasia, address, partners (QSA), CNAE, share capital, regularity status. POST /v1/kyb/cnpj.

biometrics_face_match

Compare a selfie against a document photo (RG / CNH front). Returns match_score (0..1) and liveness verdict. POST /v1/biometrics/face-match.

biometrics_liveness

Passive liveness check on a selfie (no document). Returns liveness_score (0..1) + spoofing_indicators. POST /v1/biometrics/liveness.

documents_ocr

OCR a Brazilian ID document (RG / CNH / CRLV / proof of residence / passport). Returns extracted structured fields per document type. POST /v1/documents/ocr.

antifraud_score

Compute Certta's antifraud risk score for an applicant given KYC + biometrics + device signals. 0..100 (higher = riskier). POST /v1/antifraud/score.

signature_icp_create

Create an ICP-Brasil digital signature envelope for one or more documents. Returns envelope_id + signers' authorization URLs. POST /v1/signature/icp/envelopes.

signature_electronic_create

Create a GoCertta electronic signature envelope (e-signature without ICP-Brasil cert — lower legal weight, faster UX). POST /v1/signature/electronic/envelopes.

signature_get_envelope

Get status + signer responses for a signature envelope. GET /v1/signature/envelopes/{envelope_id}.

onboarding_process_create

Kick off an orchestrated onboarding pipeline that chains KYC + biometrics + signature in one call. Returns process_id; track via onboarding_process_get. POST /v1/onboarding/processes.

onboarding_process_get

Get status + results of an onboarding process. Each step (KYC, biometrics, signature) reports its own verdict. GET /v1/onboarding/processes/{process_id}.

Names and descriptions come from the package's tools/list (@codespar/mcp-certta@0.1.3). A kind (read, write, delete) is shown only when the package annotates its tools or each tool was verified one by one; neither exists for this server yet.

Compatibility

Questions

Before you install.

How do I install the Certta MCP server?

The npm package @codespar/mcp-certta is deprecated, so this page shows no install command for it. The registry says: No live endpoint: api.certta.com.br does not resolve. See https://github.com/codespar/mcp-dev-latam/tree/main/packages/identity/certta

What can my agent do with Certta?

Certta exposes 11 tools for identity & kyc. Your agent calls them directly; the full list is above.

How does Certta authenticate, and how are credentials stored?

Certta uses API Key. Self-hosted, you hold the credentials: the server reads them from its environment variables.

How does Certta handle upstream API changes?

Every server is versioned independently on npm. This one is deprecated (see the notice above), so the page does not suggest pinning a version.

Is Certta open source? How do I report a bug?

Yes. Certta is MIT-licensed and published on npm as @codespar/mcp-certta, source on GitHub (link in the Details panel). Report issues on the package repository; security issues go to security@codespar.dev, and we respond within 24 hours.
