What can you do with this server?

The BCB MCP server provides access to Brazilian Central Bank (BCB/SGS) economic and financial time series data through AI assistants via the Model Context Protocol, enabling querying, analysis, and comparison of key Brazilian economic indicators. * Query historical data (bcb_serie_valores): Retrieve time series values by code with optional date filters. * Get latest values (bcb_serie_ultimos): Fetch the most recent 1–1000 values of any series. * Access series metadata (bcb_serie_metadados): Get details such as name, frequency, category, and source. * Browse popular series (bcb_series_populares): List 150+ curated indicators across 12 categories (Interest Rates, Inflation, Exchange Rates, Economic Activity, Employment, Fiscal, External Sector, Credit, Monetary Aggregates, Savings, Market Indices, Expectations). * Search for series (bcb_buscar_serie): Find series by keyword with accent-insensitive search (e.g., "inflacao" matches "Inflação"). * Check current indicators (bcb_indicadores_atuais): Get the latest values for Selic, IPCA, USD/BRL (PTAX), and IBC-Br. * Calculate variations (bcb_variacao): Compute percentage changes between dates or over the last N periods, with stats like max, min, and average. * Compare multiple series (bcb_comparar): Analyze 2–5 series simultaneously over the same period with ranking. The server covers 18,000+ time series and includes 30-second timeouts, auto-retry with exponential backoff, and clear error handling.

Leia em Português

MCP (Model Context Protocol) server for the Brazilian Central Bank (Banco Central do Brasil, BCB) time series data (SGS/BCB).

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: 15 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 - 139 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

Available Tools

Tool	Description
`bcb_serie_valores`	Query series values by code and date range; slices long windows automatically and can harmonise the series to a coarser frequency

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"
    }
  }
}

Series Catalog (139)

The curated catalog holds 139 series, each verified against the source on 2026-08-13.

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 (57 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.

The full machine-readable catalog is served as the bcb://series/populares resource and by bcb_series_populares. Thousands of further series are reachable through bcb_buscar_serie, which also queries the BCB Open Data Portal index.

Finding Other Series

The SGS database contains over 18,000 time series. To find codes for other series:

Visit the BCB SGS Portal
Search for the desired series
Note the series code
Use that code with this server's tools

Technical Details

Robustness

Timeout: 30 seconds per request (prevents hanging)
Auto-retry: 3 attempts with exponential backoff (1s, 2s, 4s) for transient failures; client errors (4xx) are not retried, since they are deterministic
Error handling: Clear error messages

Working around the SGS limits

Measured against the live API, not inferred from documentation:

A date window over 10 years on a daily series is refused with HTTP 406, and so is an open window (no dataInicial, or no dates at all). The limit applies to the implicit window: with no dataFinal the API assumes today. Requests are sliced into windows of up to 3 years, fetched with bounded concurrency and merged in date order without duplicating the seams; the response reports it in chunking. The slice is 3 years rather than the allowed 10 because a 10-year daily window costs 10–20 s upstream and may be cut off around 30 s.
dados/ultimos/N is capped at 20 by the API, in every periodicity. Above 20, the server infers the series' periodicity and fetches by date window instead.
There is no per-series metadata endpoint (/metadados answers 404). Frequency is inferred from the spacing of the observations and flagged with periodicidadeInferida; unit of measure is not available from any source.

Derived values

Anything this server computes — variation, descriptive statistics, harmonised series — is marked derived: true and carries a note with the conventions used. Statistics come from @sbissoli/mcp-stats. A value published by the BCB is always returned verbatim; only computed values are rounded (to 4 decimals).

Smart Search

bcb_buscar_serie searches two layers: the curated curated catalog of 139 verified series (which ranks first, with the name source declared names) and the index of the BCB Open Data Portal, with thousands of series identified by code. Terms are accent- and case-insensitive, and several terms are combined with AND:

"inflacao" → finds "Inflação"
"cambio" → finds "Câmbio"
"ipca servicos" → both terms must match

The portal index is served from a 24-hour cache, renewed by the first search after it expires (one request to the portal, only metadata — series codes and names, never observations). Every answer carries catalogo.cobertura: the index is not the whole SGS, so not finding a series here is not proof it does not exist.

Data source and licence

Data obtained from the Banco Central do Brasil (SGS / Olinda-Expectativas / PTAX), published under the Open Data Commons Open Database License (ODbL) v1.0 — https://opendatacommons.org/licenses/odbl/. Exchange-rate answers pass through the BCB's own liability disclaimer verbatim; cross-currency parities are not compiled by the BCB — they come from an information agency (Refinitiv) and are redistributed by the BCB, and the tools say so.

Documentation: BCB Open Data

Changelog

v1.4.1

bcb_focus_referencias: the parameter is now escopo, not horizonte, and the response array is escopos. The scopes are the five horizons of bcb_focus_expectativas plus selic — and selic is not a horizon: its axis is the Copom meeting. Each block names the tool that consumes it. The previous name implied selic was a queryable horizon of bcb_focus_expectativas, which it is not. Never published to npm under the old name.

v1.4.0

Three APIs under one contract, 8 tools → 13. Focus market-expectations survey (bcb_focus_expectativas, bcb_focus_selic, bcb_focus_referencias) and PTAX exchange rates (bcb_cambio_cotacao, bcb_cambio_moedas), consolidated by parameter rather than mirroring the source's ~18 OData resources.
Real search. bcb_buscar_serie now queries the Open Data Portal index (3,500+ series, 24-hour cache, metadata only) on top of the curated catalog, and states the index's coverage instead of claiming a series does not exist.
Every Focus and PTAX field name verified against the live API, including the Top 5 Selic resource, which publishes its fields in a different case from the other twelve.
ODbL obligations shipped with the exchange-rate tools: the BCB disclaimer is passed through verbatim, and non-USD parities are qualified as third-party (Refinitiv) data redistributed by the BCB.
