An MCP server for Certta, a Brazilian identity and business-verification service. It provides access to biometric checks, document reading, Brazilian digital signatures, and onboarding, and requires Certta credentials.

Use it in applications that need Brazilian customer or business onboarding, document extraction, biometric verification, or ICP-Brasil electronic signatures.

It gives a coding agent a defined connection to these verification services instead of making each integration from scratch.

Security

Grade A, and why

mcp-certta scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
