Casos de uso

Usos do mundo real: mcp-brasil

How to track a Brazilian bill through Câmara and Senado

👤 Journalists, policy analysts, government affairs teams ⏱ ~15 min beginner

Quando usar: You need to follow a specific proposition (PL/PEC) across votes, amendments, and committee stages without scraping websites.

Pré-requisitos

The bill identifier (e.g. PL 2630/2020) — From a Câmara/Senado URL or news article

Fluxo

Find the proposition and its current status

Use mcp-brasil to find PL 2630/2020 in Câmara. Show current status, author, and tramitação timeline.✓ Copiado

→ Structured response with bill metadata and stage history
Pull votes and committee actions

List every vote and committee action on that bill, with dates and results.✓ Copiado

→ Chronological list of events
Summarize for a briefing

Write a 3-paragraph briefing: where the bill stands today, who's pushing it, and the most likely next step.✓ Copiado

→ Ready-to-publish policy summary

Resultado: A sourced legislative brief built from primary Câmara/Senado data in under 10 minutes.

Armadilhas

Bill IDs collide across houses — PL in Câmara ≠ PLS in Senado — Always specify the house; use planejar_consulta to query both if uncertain

Audit Brazilian government contracts with mcp-brasil

👤 Investigative reporters, transparency NGOs ⏱ ~40 min advanced

Quando usar: You suspect irregular spending by a federal body and want to cross-check Portal da Transparência, sanctions registry, and contract data.

Pré-requisitos

Free Portal da Transparência API key — api.portaldatransparencia.gov.br — takes a minute, set TRANSPARENCIA_API_KEY

Fluxo

List recent contracts for the target entity

Get the top 20 largest contracts signed by Ministério X in the last 12 months, with supplier CNPJs.✓ Copiado

→ Table of contracts with values and CNPJs
Check suppliers against the sanctions registry (CEIS/CEPIM)

For each CNPJ, check if it appears in CEIS or CEPIM sanctions. Flag matches.✓ Copiado

→ Supplier-by-supplier compliance status
Cross-reference with public servant data

Use executar_lote to parallelize partner lookups across all flagged CNPJs.✓ Copiado

→ Potential conflict-of-interest leads

Resultado: A data-backed lead list you can hand to a legal or journalistic team for verification.

Armadilhas

Hitting Transparência rate limits mid-audit — Throttle with batch size 10; executar_lote handles back-off
Treating surname matches as proof — Always verify manually — this is lead generation, not conclusion

Combine com: google-sheets

Build a live Brazilian macro dashboard with mcp-brasil

👤 Economists, fintech PMs, analysts ⏱ ~10 min beginner

Quando usar: You need daily SELIC, IPCA, câmbio without wiring BCB/IBGE APIs manually.

Fluxo

Ferramentas

O que este MCP expõe

Ferramenta	Entradas	Quando chamar	Custo
planejar_consulta	question: str	Start of any cross-API investigation — lets the server pick the right endpoints	1 local call
executar_lote	calls: Call[]	You have a list of CNPJs/CPFs/bill IDs to enrich in one shot	N upstream calls parallelized
listar_features		Discover what domains are covered before drafting a prompt	0
recomendar_tools	query: str	You know what you want but not which of the 363 tools fits	0

Custo e limites

O que custa rodar

Cota de API: Upstream varies: Câmara/Senado effectively unlimited; Transparência ~90 req/min per key; IBGE/BCB generous
Tokens por chamada: 100–1500 depending on endpoint
Monetário: Free — all underlying APIs are public
Dica: Use planejar_consulta first to avoid firing 10 tools when 2 suffice

Segurança

Permissões, segredos, alcance

Armazenamento de credenciais: Optional keys in env vars TRANSPARENCIA_API_KEY, DATAJUD_API_KEY, META_ACCESS_TOKEN

Saída de dados: Calls go to Brazilian government domains (gov.br, ibge.gov.br, bcb.gov.br) and Meta Ad Library

Solução de problemas

Erros comuns e correções

429 Too Many Requests (Portal da Transparência)

Reduce batch size in executar_lote to 5 and add pauses; Transparência is the strictest upstream

Verificar: Re-run the same call after 60s

Tool not found / unknown feature

Run listar_features then recomendar_tools with your natural-language query — the 363-tool surface requires discovery

Empty result for a valid CNPJ

Not all CNPJs appear in every registry; check Receita Federal base first

Alternativas

mcp-brasil vs. outros

Alternativa	Quando usar	Troca
BrasilAPI	You only need CEP/CNPJ/banks and want a single HTTP call	Tiny surface compared to mcp-brasil's 363 tools
Direct gov.br API calls	You're building a production backend, not an AI agent workflow	You write all the plumbing yourself
