Compatible with every major AI agent and IDE
What is the IBGE Nomes MCP Server?
Connect to the IBGE (Brazilian Institute of Geography and Statistics) database through any AI agent to explore the rich demographic history of Brazilian names. This server provides direct access to the 'Nomes no Brasil' census data.
What you can do
- Name Frequency — Query the number of births per decade for specific names (e.g., 'MARIA' or 'ENZO') to see how trends evolved over time.
- Rankings & Popularity — Generate rankings of the most frequent names in Brazil, with optional filters for gender and specific decades.
- Geographic Insights — Filter results by locality ID to understand regional naming preferences across different Brazilian states and municipalities.
- Comparative Analysis — Use the pipe separator to compare multiple names simultaneously and identify cultural shifts.
How it works
- Subscribe to this server
- No API key is required as it uses the public IBGE Open Data API
- Start querying Brazilian name statistics from Claude, Cursor, or any MCP client
Who is this for?
- Data Analysts & Sociologists — study naming trends and demographic shifts in the Brazilian population.
- Content Creators & Writers — find historically accurate names for characters based on specific decades in Brazil.
- Developers — integrate official Brazilian demographic data into applications without complex setup.
Built-in capabilities (2)
Multiple names can be separated by a pipe (|). Obtains the frequency of births per decade for a specific name
Obtains a ranking of the most frequent names according to specified filters
Why Pydantic AI?
Pydantic AI validates every IBGE Nomes tool response against typed schemas, catching data inconsistencies at build time. Connect 2 tools through Vinkius and switch between OpenAI, Anthropic, or Gemini without changing your integration code. full type safety, structured output guarantees, and dependency injection for testable agents.

Why teams choose Vinkius for IBGE Nomes in Pydantic AI
The IBGE Nomes MCP Server runs on Vinkius-managed infrastructure inside AWS — a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts. All 2 tools execute in hardened sandboxes optimized for native MCP execution.
Your AI agents in Pydantic AI only access the data you authorize, with DLP that blocks sensitive information from ever reaching the model, kill switch for instant shutdown, and up to 60% token savings. Enterprise-grade infrastructure, zero maintenance.

* Every MCP server runs on Vinkius-managed infrastructure inside AWS - a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts optimized for native MCP execution. See our infrastructure
How Vinkius secures
IBGE Nomes for Pydantic AI
Every tool call from Pydantic AI to the IBGE Nomes MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
Can I compare the popularity of two different names in the same query?
Yes! Use the get_name_frequency tool and separate the names with a pipe symbol (e.g., 'MARIA|ANA'). The agent will return the frequency data for both names across the decades.
How do I find the most popular names from the 1990s?
You can use the get_names_ranking tool and provide '1990' in the decada parameter. This will return a list of the most frequent names recorded during that specific period.
Is it possible to filter name statistics by a specific Brazilian state?
Absolutely. Both get_name_frequency and get_names_ranking accept a localidade parameter. You just need to provide the IBGE ID for the target state or municipality.
How does Pydantic AI discover MCP tools?
Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.
Does Pydantic AI validate MCP tool responses?
Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.
Can I switch LLM providers without changing MCP code?
Absolutely. Pydantic AI abstracts the model layer. your IBGE Nomes MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
