### Description (declared)

# cvm-mcp

[![PyPI](https://img.shields.io/pypi/v/cvm-mcp)](https://pypi.org/project/cvm-mcp/)
[![Python](https://img.shields.io/badge/python-3.10%2B-blue)](https://www.python.org/)

[![MCP](https://img.shields.io/badge/MCP-stdio-6f42c1)](https://modelcontextprotocol.io/)

An MCP server for the [CVM open-data repository](https://dados.cvm.gov.br)
(`dados.cvm.gov.br`) — the Brazilian securities regulator and the source behind
the R packages *GetDFPData2* and *GetFREData*.

It gives Claude Code, OpenCode, Cursor, VS Code, Codex, Gemini CLI and any other
MCP client one interface to:

- annual and quarterly financial statements (DFP / ITR)
- the Formulário de Referência (FRE, 36 corporate tables)
- fund NAVs, flows, portfolios and credit-fund reports
- insider trading, governance, public offerings and sanctioning proceedings
- ad-hoc SQL over everything, via DuckDB

**15 datasets, 111 tables, 34 tools.** Everything runs locally and read-only;
data is downloaded on demand and cached on disk.

> This server consolidates the earlier `cvm-dfp-mcp` and `cvm-fre-mcp` servers
> and is a strict superset of both.
