openbq-org/OpenBB

openbb is an open-source financial data infrastructure layer that consolidates proprietary, licensed, and public financial data sources and exposes them to Python environments, OpenBB Workspace and Excel, MCP servers, and REST APIs simultaneously. It follows a 'connect once, consume everywhere' architecture for downstream applications such as AI copilots and research dashboards.

Project overview

It addresses the fragmented integration of financial data sources by serving a single connected data layer to multiple consumption surfaces at once, including Python, REST, and MCP servers for AI agents.

Project type: MCP · Data Processing
Use cases: Data Analysis · Automation
Deployment: Refer to project documentation
License: License pending

Best for

Developers and data teams who need to integrate multiple financial data sources into downstream applications such as AI copilots and research dashboards.
AI engineers who need financial data exposed to MCP servers for AI agents.
Analysts who consume data through Excel or the OpenBB Workspace UI.

Key capabilities

Fetch financial data such as historical equity prices via a Python API (obb.equity.price.historical) and convert results to dataframes.
Launch a FastAPI server via Uvicorn at 127.0.0.1:6900 serving the platform's data over REST.
Consolidates and exposes data to MCP servers for AI agents as one of the consumption surfaces.
Command-line interface (openbb-cli) to access the ODP directly from the command line.
Connect the locally run ODP backend to the OpenBB Workspace UI via 'Connect backend' to visualize datasets.

Limitations and risks

Data contained in the Open Data Platform is not necessarily accurate; verify data before relying on it for decisions.

Getting started

Install with a single 'pip install openbb', then fetch historical prices in Python with obb.equity.price.historical('AAPL').
