OpenBB Workspace now supports MCP servers. But we've gone beyond simple integration. Read on to learn how we’re making MCP reliable for institutional finance.
The Model Context Protocol (MCP) is gaining traction fast. It promises to make datasets instantly accessible to AI agents through a standardized interface, regardless of where the data comes from.
On paper, it's a revolution: instead of each integration being a custom project, MCP makes them plug-and-play.
However, in reality, data is messy, especially in finance.
Getting an answer is easy. Getting the right answer is what separates an impressive demo from something a portfolio manager can trust.
The trust problem in MCP adoption
Consider job postings data. At first glance, it's a simple metric. You count the number of new postings and track the trend. But…
- Which geographies are covered?
- Are reposted or duplicate jobs removed?
- Are expired postings kept for historical context?
- Are third-party recruiter listings included?
One provider may report 10,000 openings in a sector, another 6,500 for the same period, purely because of differences in filtering, aggregation, and classification.
Without visibility into how the answer was produced, an AI-powered query might give you a clean number, but not a trustworthy one. And the moment that number drives an investment decision, the stakes get real.
OpenBB's answer: transparent and auditable MCP integration
OpenBB Workspace was built on a simple principle: if you can't see the data behind the insights, you can't fully trust it.
We've spent three years building the connectors, widget system, and interface layer needed to make heterogeneous data sources feel seamless, and above all, auditable. MCP fits into our architecture like it was designed for it.
While other platforms can connect to MCP, they can't tell you where the answer came from. OpenBB makes that traceability part of the user experience.
What this means for OpenBB users
Your AI-powered analysts can instantly use MCP servers exposed by vendors or your own infrastructure.
You can combine MCP servers with data from your OpenBB apps for richer workflows.
No one-off integrations are needed. If it speaks MCP, it works inside Workspace. MCP's open standard eliminates the need for vendor-specific integrations.
Through MCP support, OpenBB Workspace is ready for a growing ecosystem of AI-first financial tools. As vendors adopt the protocol, their capabilities can be leveraged instantly inside your OpenBB Workspace, meaning your research and analytics workflows gain new skills as rapidly as the ecosystem expands.
How does it work in practice?
1. Every MCP can become a widget
Any output produced by the MCP can be pulled directly into OpenBB Workspace as a widget.
2. Full parameter control
We map MCP server parameters into our widgets.json format, letting you see and edit exactly what's being queried. Every widget can be represented in a structured way: inputs, outputs, parameters, and controls.
3. Raw Data On Demand
With one click, you can see the full dataset behind an MCP response. No black boxes, no guesswork.
4. In-context data manipulation
If an LLM or agent manipulates the data before showing it to you, those transformations are visible and auditable.
Why this matters for financial institutions
Historically, firms had to choose between:
UI-first systems that serve analysts well but create automation bottlenecks
AI-first protocols that enable automation but lack intuitive interfaces for human oversight
With OpenBB Workspace, you don’t have to choose.
widgets.json enables UI-first interfaces that AI-powered systems can also consume for building data-driven dashboards.
MCP provides a standardized way for intelligent systems to access external tools and data.
Together, they make the Workspace both more powerful for humans and more capable for automated workflows.
When everyone has access, what’s your competitive advantage?
As MCP becomes standard across financial institutions, the real differentiator won't be access, but trust.
OpenBB is positioned to be your trusted interface for MCP because it’s:
Vendor-agnostic: Any MCP server works instantly
Audit-friendly: Full transparency into data sources
Enterprise-ready: Secure architecture that maintains compliance standards
We're making MCP reliable. And in finance, that's what allows you to go from a proof-of-concept to production.
In a market where anyone can give you an answer, OpenBB gives you the proof.
