Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Banco Central do Brasil (BCB): SGS series, Focus expectations, PTAX, stats + provenance. 17 tools.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
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.
The registry does not list a required key, though some servers ask you to sign in on first use.
Either way works: install it on your computer or connect to the cloud version.

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.
Ask your assistant, in plain Portuguese:
bcb_indicadores_atuaisbcb_serie_valoresbcb_variacaobcb_focus_expectativasbcb_focus_selicbcb_cambio_cotacaoThe answers come live from the Brazilian Central Bank's SGS API — exact figures with provenance, not numbers guessed from training data.
📖 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.
| 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 |
bcb_serie_ultimos | Get the last N values of a series (any N — the upstream cap of 20 is worked around) |
bcb_serie_metadados | Get series metadata (name, frequency, category, last value) |
bcb_series_populares | List popular series grouped by category |
bcb_buscar_serie | Search 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_atuais | Latest values: Selic, IPCA, USD/BRL, IBC-Br |
bcb_variacao | Percentage 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_comparar | Compare 2 to 5 series over the same period with ranking (same level/compounding rule per series, declared in metodo) |
bcb_focus_expectativas | Focus survey expectations for one indicator, horizon as a parameter (monthly, quarterly, annual, rolling 12m/24m inflation); top5 flag |
bcb_focus_selic | Focus expectations for the Selic rate, by Copom meeting (R1/2026 form) |
bcb_focus_referencias | Which 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_cotacao | PTAX quote for a currency (USD by default), single day or date range |
bcb_cambio_moedas | Currencies with quotes published by the BCB |
search | OpenAI Deep Research contract: searches the series catalog (curated + open data portal index) and returns { id, title, url } — see ChatGPT (Deep Research) |
fetch | OpenAI Deep Research contract: returns one series as a readable document with its canonical public URL |
Reference catalogs the server exposes as MCP resources (read-only contextual data that clients can attach):
| URI | Description |
|---|---|
bcb://series/populares | Catalog of 135 verified BCB economic series, organized by category (JSON) |
bcb://series/categorias | List of available categories in the series catalog (JSON) |
bcb://series/principais | Codes of the most-used indicators — Selic, IPCA, USD/BRL, GDP, etc. (JSON) |
Ready-made templates the server provides as MCP prompts:
| Prompt | Description |
|---|---|
indicadores_atuais | Query Brazil's key economic indicators (Selic, IPCA, USD/BRL, IBC-Br) |
panorama_economico | Generate a complete overview of the Brazilian economy |
comparar_inflacao | Compare Brazil's main inflation indices (IPCA, IGP-M, INPC) over the last 12 months |
Visit bcb-br-mcp on Smithery and follow the installation instructions for your 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.
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"] } } }
npm install -g bcb-br-mcp
{
"mcpServers": { "bcb-br": { "command": "bcb-br-mcp" } } }
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.
What is the current Selic interest rate?
→ Uses bcb_indicadores_atuais
Show me the monthly IPCA for 2024
→ Uses bcb_serie_valores with code 433, dataInicial 2024-01-01, dataFinal 2024-12-31
What inflation series are available?
→ Uses bcb_series_populares with category "Inflação"
Search for series related to the dollar
→ Uses bcb_buscar_serie with term "dolar" (works without accents)
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 in 2024
→ Uses bcb_comparar with codes [433, 189, 188], dataInicial 2024-01-01, dataFinal 2024-12-31
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:
unidade carries the published unit of measure.Periodicity is always the measured one (from the spacing between observations), never an inherited label. Market expectations are not here — use bcb_focus_expectativas.
