Ibge Br

mcp-ibge-br

IBGE (Instituto Brasileiro de Geografia e Estatística) MCP. Brazil's official statistics agency. Keyless public API.

Part of Pipeworx — an MCP gateway connecting AI agents to 1881+ live data sources. This is an independent, unofficial integration — not affiliated with, endorsed by, or published by the upstream provider.

Tools

Tool	Description
list_states	List all 27 Brazilian states (UFs) with id, 2-letter sigla, name, and region (e.g. "SP" → São Paulo, Sudeste). Useful for resolving state names/codes before querying municipalities or regional data.
list_municipalities	List municipalities for a given state (UF). Returns each municipality with its 7-digit IBGE id and name. e.g. uf="RJ" lists all municipalities in Rio de Janeiro.
lookup_municipality	Look up a single municipality by its 7-digit IBGE code, returning full hierarchy (micro/mesoregion, state, region). e.g. code="3550308" → São Paulo (capital).
aggregated_data	Pull official IBGE/SIDRA statistical series (inflation, GDP, population, etc.). Specify the aggregate table, variable, periods, and locality. Common examples: IPCA monthly inflation = aggregate "1737" variable "63"; population estimate = aggregate "6579" variable "9324". Returns time series keyed by period.
list_aggregates	Browse the catalog of IBGE/SIDRA aggregate tables grouped by subject (inflation, agriculture, demographics, etc.). Use to discover aggregate ids to pass to aggregated_data. Optionally filter by research/subject acronym.
name_frequency	Brazilian census name statistics. Pass a first name to get its registration frequency by decade (since 1930), optionally filtered by sex or state. e.g. name="maria". Pass name="ranking" to get the top names instead.

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "ibge-br": {
      "url": "https://gateway.pipeworx.io/ibge-br/mcp"
    }
  }
}

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/ibge-br/mcp returns the tools in the table above plus the shared Pipeworx meta-tools — ask_pipeworx, discover_tools, search_within, remember/recall and the rest of the gateway-wide set. So the tool count you see is larger than this table: a single-pack endpoint currently lists roughly 30 shared tools alongside the pack's own. The connection's initialize response states its exact scope, and is the authoritative answer for a given day.

This is deliberate, not multiplexing by accident. The meta-tools are what let a scoped connection answer a question this pack does not cover — via ask_pipeworx, which routes across the whole catalog — without you adding a second MCP server. There is currently no way to mount a pack endpoint without them; if the extra schemas cost you more context than the routing is worth, connect to the full gateway once rather than to several pack endpoints.

Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Both URLs reach the same gateway and the same 1881+ data sources. The only difference is which pack's tools are listed directly; ask_pipeworx reaches all of them from either one.

No MCP client? Call it over HTTP

curl -X POST https://gateway.pipeworx.io/v1/tools/list_states \
  -H 'Content-Type: application/json' \
  -d '{"orderBy":"nome"}'

No account needed for the first calls. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/list_states. Find one: POST https://gateway.pipeworx.io/v1/tools/search_packs with {"query":"..."}.

Standalone (no gateway account)

This package also runs as a local stdio MCP server — no Pipeworx account, no gateway round-trip:

{
  "mcpServers": {
    "ibge-br": {
      "command": "npx",
      "args": ["-y", "@pipeworx/mcp-ibge-br"]
    }
  }
}

Or run it directly to confirm it starts:

npx -y @pipeworx/mcp-ibge-br

It speaks MCP over stdin/stdout and answers initialize/tools/list/tools/call for only this pack's tools — none of the shared meta-tools the gateway connection above adds. Same source, same tools, no ask_pipeworx routing.

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:

ask_pipeworx({ question: "your question about Ibge Br data" })

The gateway picks the right tool and fills the arguments automatically.
