Use Cases

Real-world ways to use mcp-brasil

How to track a Brazilian bill through Câmara and Senado

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

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

Prerequisites

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

Flow

Find the proposition and its current status

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

→ 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.✓ Copied

→ 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.✓ Copied

→ Ready-to-publish policy summary

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

Pitfalls

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

Combine with: notion

Audit Brazilian government contracts with mcp-brasil

👤 Investigative reporters, transparency NGOs ⏱ ~40 min advanced

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

Prerequisites

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

Flow

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.✓ Copied

→ 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.✓ Copied

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

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

→ Potential conflict-of-interest leads

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

Pitfalls

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 with: google-sheets

Build a live Brazilian macro dashboard with mcp-brasil

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

When to use: You need daily SELIC, IPCA, câmbio without wiring BCB/IBGE APIs manually.

Flow

Pull today's key rates

Give me today's SELIC, CDI, IPCA (12m), USD/BRL using mcp-brasil.✓ Copied

→ Current values with source + timestamp per indicator
Render a morning note

Write a morning note comparing today's values to 30 days ago, flag >1 sigma moves.✓ Copied

→ Formatted note ready to paste in Slack

Outcome: A self-refreshing macro snapshot you can schedule daily.

Combine with: google-sheets

Combinations

Pair with other MCPs for X10 leverage

brasil + google-sheets

Dump contract audits or macro snapshots straight into a shared sheet

Run today's macro snapshot with mcp-brasil and append the row to my 'Brasil Macro' Google Sheet.✓ Copied

brasil + notion

Policy tracking workspace with each bill as a Notion page

For every active PL in Comissão X, create/update a Notion page with the latest tramitação.✓ Copied

Tools

What this MCP exposes

Tool	Inputs	When to call	Cost
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

Cost & Limits

What this costs to run

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

Security

Permissions, secrets, blast radius

Credential storage: Optional keys in env vars TRANSPARENCIA_API_KEY, DATAJUD_API_KEY, META_ACCESS_TOKEN

Data egress: Calls go to Brazilian government domains (gov.br, ibge.gov.br, bcb.gov.br) and Meta Ad Library

Troubleshooting

Common errors and fixes

429 Too Many Requests (Portal da Transparência)

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

Verify: 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

Alternatives

mcp-brasil vs others

Alternative	When to use it instead	Tradeoff
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
