Common questions

Is Banco Central do Brasil (BCB) — SGS Time Series MCP Server safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.19.0) reached the registry 11 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Spec Driven Development, Remote Desktop Commander, Filesystem MCP

Banco Central do Brasil (BCB) — SGS Time Series MCP Server

Leia em Português

MCP (Model Context Protocol) server for the Brazilian Central Bank (Banco Central do Brasil, BCB): SGS time series (SGS/BCB), the Focus market-expectations survey (served over the Olinda OData API) and PTAX exchange rates.

Query economic and financial indicators such as Selic (interest rate), IPCA (inflation), exchange rates, GDP, and more, directly from AI assistants like Claude.

If you find this project useful, please consider giving it a star on GitHub. It helps others discover the project!

Capabilities: 17 tools (skills) · 3 resources · 3 prompts — everything an MCP client needs to query the Brazilian Central Bank: SGS/BCB time series, the Focus market-expectations survey and PTAX exchange rates.

See it in action

Ask your assistant, in plain Portuguese:

  • *"Qual a taxa Selic atual?"* → bcb_indicadores_atuais
  • *"Mostre o IPCA mês a mês em 2024."* → bcb_serie_valores
  • *"Qual foi a variação do dólar nos últimos 12 meses?"* → bcb_variacao
  • *"O que o mercado espera do IPCA em 2027?"* → bcb_focus_expectativas
  • *"Qual a Selic esperada na próxima reunião do Copom?"* → bcb_focus_selic
  • *"Qual foi a PTAX de fechamento do euro na sexta?"* → bcb_cambio_cotacao

The answers come live from the Brazilian Central Bank's SGS API — exact figures with provenance, not numbers guessed from training data.

Features

  • Historical data - Query time series values by code with date filters
  • Latest values - Get the most recent N values of any series
  • Metadata - Detailed information about series (frequency, source, etc.)
  • Popular series catalog - 135 economic indicators verified against the source, organized by category
  • Smart search - Find series by keyword (accent-insensitive)
  • Current indicators - Latest values for key economic indicators
  • Long periods, handled - The BCB API caps daily series at a 10-year window (HTTP 406) and refuses open windows; requests are sliced, fetched and merged automatically, so a 15-year daily query just works
  • Frequency harmonisation - Resample a series to monthly, quarterly or annual with an explicit convention, including geometric compounding for series that already are percentage changes (monthly IPCA into annual IPCA)
  • Variation calculation - Percentage change between periods with statistics
  • Series comparison - Compare multiple series over the same period, with a warning when their periodicities differ
  • Focus survey - Market expectations (mean, median, std. deviation, min, max, respondents) for IPCA, GDP, FX and more, by monthly/quarterly/annual horizon or rolling 12/24-month inflation, plus Selic by Copom meeting
  • PTAX exchange rates - Official closing quotes for any currency the BCB publishes, single day or date range

📖 Article (in Portuguese): Séries do Banco Central: como consultar o SGS, a Focus e a PTAX sem cair nas armadilhas — the three API limits measured live, level vs. rate series, the Focus scopes, and what the ODbL requires. Also published on the site, in Portuguese and English: sidneybissoli.com.

Available Tools

ToolDescription
bcb_serie_valoresQuery series values by code and date range; slices long windows automatically and can harmonise the series to a coarser frequency

bcb_serie_metadadosGet series metadata (name, frequency, category, last value)
bcb_series_popularesList popular series grouped by category
bcb_buscar_serieSearch series by name or description (accent-insensitive, AND between words; everyday words resolved to the BCB's wording, and the response says so)
bcb_indicadores_atuaisLatest values: Selic, IPCA, USD/BRL, IBC-Br
bcb_variacaoPercentage variation of one series over a period: level change for level series, compounded accumulation for series that are already period-on-period rates (IPCA, IGP-M, INPC…); analise.metodo says which
bcb_compararCompare 2 to 5 series over the same period with ranking (same level/compounding rule per series, declared in metodo)

bcb_focus_selicFocus expectations for the Selic rate, by Copom meeting (R1/2026 form)
bcb_focus_referenciasWhich indicators and reference dates the Focus survey actually publishes, broken down per scope (the five horizons plus selic, whose axis is the Copom meeting) — the indicator set differs by scope (9 monthly vs 26 annual)
bcb_cambio_cotacaoPTAX quote for a currency (USD by default), single day or date range
bcb_cambio_moedasCurrencies with quotes published by the BCB
searchOpenAI Deep Research contract: searches the series catalog (curated + open data portal index) and returns { id, title, url } — see ChatGPT (Deep Research)
fetchOpenAI Deep Research contract: returns one series as a readable document with its canonical public URL

Resources

Reference catalogs the server exposes as MCP resources (read-only contextual data that clients can attach):

URIDescription
bcb://series/popularesCatalog of 135 verified BCB economic series, organized by category (JSON)
bcb://series/categoriasList of available categories in the series catalog (JSON)
bcb://series/principaisCodes of the most-used indicators — Selic, IPCA, USD/BRL, GDP, etc. (JSON)

Prompts

Ready-made templates the server provides as MCP prompts:

PromptDescription
indicadores_atuaisQuery Brazil's key economic indicators (Selic, IPCA, USD/BRL, IBC-Br)
panorama_economicoGenerate a complete overview of the Brazilian economy
comparar_inflacaoCompare Brazil's main inflation indices (IPCA, IGP-M, INPC) over the last 12 months

Installation

Via Smithery (recommended)

Visit bcb-br-mcp on Smithery and follow the installation instructions for your MCP client.

Via URL (Claude.ai, Claude Desktop, any MCP client)

Use the HTTP endpoint directly, no installation required:

https://bcb.sidneybissoli.com/mcp

The legacy hostname https://bcb.sidneybissoli.workers.dev keeps working, and so does the older POST / route — clients configured before the endpoint moved to /mcp are rewritten transparently, so nothing that used to work stopped working. New setups should use the URL above.

Via npx (Claude Desktop)

Add to your Claude Desktop configuration file:

Windows: %APPDATA%\Claude\claude_desktop_config.json

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

{

"mcpServers": { "bcb-br": { "command": "npx", "args": ["-y", "bcb-br-mcp"] } } }

Via global install
npm install -g bcb-br-mcp
{

"mcpServers": { "bcb-br": { "command": "bcb-br-mcp" } } }

ChatGPT (Deep Research)

ChatGPT deep research (and company knowledge, and research workflows over the Responses API) only uses an MCP server that exposes exactly search and fetch — this server does, on top of the bcb_* tools. Point the connector at the hosted endpoint, no key required:

https://bcb.sidneybissoli.com/mcp

search ranks the query against the series catalog — the 135 curated series plus the thousands indexed from the Open Data Portal — and returns { id, title, url } (ids are sgs: ); fetch returns the series as readable Markdown (name, category, frequency, unit, latest value) with the canonical public URL, which is what ChatGPT cites: the dataset page on dadosabertos.bcb.gov.br when the series has one, otherwise the public SGS query for its latest observations (the SGS has no per-series page). Both carry the same provenance block as every other tool. In ChatGPT's developer mode (Settings → Security and login → Developer mode) any tool is callable — the bcb_* tools remain the ones to use for data.

Usage Examples

Get the current Selic rate
What is the current Selic interest rate?

→ Uses bcb_indicadores_atuais

IPCA history for 2024
Show me the monthly IPCA for 2024

→ Uses bcb_serie_valores with code 433, dataInicial 2024-01-01, dataFinal 2024-12-31

List inflation indicators
What inflation series are available?

→ Uses bcb_series_populares with category "Inflação"

Search for USD exchange rate series
Search for series related to the dollar

→ Uses bcb_buscar_serie with term "dolar" (works without accents)

Calculate USD/BRL variation
What was the USD/BRL variation over the last 12 months?

→ Uses bcb_variacao with code 1 and periodos 12

Compare IPCA, IGP-M, and INPC
Compare IPCA, IGP-M, and INPC in 2024

→ Uses bcb_comparar with codes [433, 189, 188], dataInicial 2024-01-01, dataFinal 2024-12-31

Series Catalog (135)

The curated catalog holds 135 series, each verified against the source on 2026-08-13 (4 discontinued FGV series were removed on 2026-08-23).

The fonteNome field on every entry says where its name comes from:

  • `portal` (82 series) — the name is transcribed from the series' dataset on the BCB Open Data Portal, and unidade carries the published unit of measure.
  • `medido` (53 series) — the series has no dataset on the portal, so the name is inherited; what was verified against the source is its periodicity and order of magnitude.

Periodicity is always the measured one (from the spacing between observations), never an inherited label. Market expectations are not here — use bcb_focus_expectativas.
