Mcp Ibge Br — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited Mcp Ibge Br (Agent Skill) and scored it 100/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 0 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

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 1856+ live data sources. This is an independent, unofficial integration — not affiliated with, endorsed by, or published by the upstream provider.
| 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. |

"ibge-br": {
"url": "https://gateway.pipeworx.io/ibge-br/mcp"
}
}
}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 1856+ data sources. The only difference is which pack's tools are listed directly; ask_pipeworx reaches all of them from either one.
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":"..."}.
@pipeworx/mcp-ibge-br is a local stdio bridge to the Pipeworx gateway: your MCP client starts it with npx, and it forwards every call to the same https://gateway.pipeworx.io/ibge-br/mcp endpoint shown above. It needs network access; there is no offline mode.
{
"mcpServers": {
"ibge-br": {
"command": "npx",
"args": ["-y", "@pipeworx/mcp-ibge-br"]
}
}
}Without a key it calls anonymously, capped at 50 calls a day. A free account raises that to 200 a day: get a key at https://pipeworx.io/signup and add "env": { "PIPEWORX_API_KEY": "<your key>" } to the server entry. The key is sent as a Bearer token, the same way a hosted connection sends it, so calls are metered and billed exactly as they are there.
It lists only this pack's tools by default. Set PIPEWORX_META_TOOLS=1 to also list ask_pipeworx and the other gateway-wide tools.
Behind an HTTPS proxy: Node's built-in fetch does not read HTTPS_PROXY by default. Newer Node releases honour it when NODE_USE_ENV_PROXY=1 is set; check your Node version's documentation.
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.
