OpenBB
OpenBB's Open Data Platform connects financial, economic and market data sources once and exposes them to Python environments, spreadsheets, MCP servers for AI agents, and REST APIs.
The platform is aimed at data engineers who need to integrate proprietary, licensed and public financial data sources into downstream applications such as AI copilots and research dashboards, following a "connect once, consume everywhere" model. A Python package gives quants a typed interface such as pulling historical equity prices into a dataframe, while the same integrations reach OpenBB Workspace and Excel for analysts, MCP servers for agents, and REST APIs for other applications.
An accompanying FastAPI backend, run over Uvicorn, can be connected to the separate OpenBB Workspace enterprise UI so analysts can visualize datasets and attach AI agents without leaving that interface.
Supports Python 3.9 through 3.12, installed as a pip package with a companion CLI. License unspecified ("NOASSERTION") in repository metadata.
