Open Source MCP Server Connects Claude to Brazilian Central Bank Economic Data
bcb-br-mcp is an open source Model Context Protocol server that connects Claude to economic data from Brazil's Central Bank. The server provides access to over 18,000 time series from the SGS/BCB system through Claude's interface.
Key Details
The server includes 8 tools covering these economic categories:
- Interest rates
- Inflation
- Exchange rates
- GDP
- Employment
- Credit
It provides access to 150+ curated indicators with accent-insensitive search functionality. Examples of queries you can ask Claude include:
- "What is the current Selic interest rate?"
- "Show me monthly inflation (IPCA) for 2024"
- "Compare IPCA, IGP-M, and INPC over the last 12 months"
- "What was the USD/BRL variation in the last 6 months?"
Setup Options
Three setup methods are available:
- Remote (no install):

The server works with Claude Desktop, Claude.ai, Claude Code, Cursor, and any MCP client. It's MIT licensed and available on GitHub at https://github.com/SidneyBissoli/bcb-br-mcp.
This type of MCP server is useful for developers working with Brazilian economic data who want to query it directly through Claude's interface without switching between tools.
