One governed model

Every source unified, mapped, and rolled up before any AI sees it.

Your business logic

Your chart of accounts, formulas, and versions. Not generic patterns.

Your permissions

Each user’s AI sees only what that user is allowed to see.

Trace to the source

Every answer drills back to the transaction, ready for the board.

Write back from your AI

Update forecasts and assumptions right from Claude or ChatGPT, with approvals and audit trail.

You’re not choosing between Cube and AI. Cube is what makes AI trustworthy for finance.
The problem

You live in your AI assistant. Your numbers still need a login.

Your assistant already reaches the rest of the stack through MCP. Finance is the holdout, so the work stops while someone goes and fetches a number.

No permissions, no lineage, no audit trail. AI can be 80% right, and in finance that is 100% wrong.

We asked Claude for our numbers. Only Claude + Cube got every one right.

We asked Claude 531 finance questions with exported spreadsheets, then again connected to Cube. On files, it got 65.7% right. In finance, 65% right is 100% wrong.

Why Cube

The MCP server for finance, not another connector.

Generic connectors return rows. Cube returns decision-ready answers from a governed financial model, with permissions and lineage enforced on every query.

Generic database or ERP MCPs

Hands your assistant raw tables. It doesn’t know what gross margin means in your model, which forecast version is current, or who can see exec comp.

The alternative
Building AI on raw ERP APIs

Means rebuilding permissions, metric definitions, and audit logging yourself, then maintaining all three as your business changes.

Governed answers, out of the box

Your business logic, roll-ups, and permissions applied before the assistant sees a number. Every figure traces to the transaction.

Make every AI tool in the company finance-literate.

Connect your assistant to a governed Cube model and drill every answer to the source.

Common questions

Everything you need to know about the Cube MCP Server.

What is an MCP server for finance?

An MCP server for finance is a Model Context Protocol server that gives AI assistants governed access to your financial model, with permissions and transaction lineage enforced on every query. The answer comes from the same governed model Cube delivers everywhere your team works.

Which AI assistants work with the Cube MCP Server?

The Cube MCP Server works with Claude, ChatGPT, Copilot, Gemini, and any MCP-compatible assistant. The connection is OAuth-secured and takes under a minute, with no exports and no developer resources.

What is the best MCP server for financial data?

The best MCP server for financial data gives AI assistants governed, calculated numbers rather than raw ledger rows, respects each user’s permissions, and logs every read and write. The Cube MCP Server connects Claude, ChatGPT, Copilot, and Gemini to Cube’s governed financial context, so answers match the board deck and approved changes write back to Cube.

How do you connect Claude or ChatGPT to financial data securely?

Connect the assistant through an MCP server that enforces the same access controls, audit trail, and business rules as your finance system, instead of pasting exports into a chat. With Cube, users sign in with their own permissions, the assistant only sees what they can see, and every action is recorded in Cube’s SOC 1 and SOC 2 Type II audited platform. 

Can an AI assistant change my numbers?

Only if you allow it. Write-back requires a dedicated permission, Use MCP (Write), granted by your admins. Every change lands in the audit trail with before and after values.

Does the assistant see data the user can’t?

No. Access follows each user’s Cube permissions, down to the cell. An assistant acting for a VP sees that VP’s cost center; one acting for the CFO sees everything.

How is this different from pasting data into ChatGPT?

Cube gives the assistant live, governed data instead of a pasted copy. Pasted data is a stale copy with no permissions or lineage. Through Cube, the assistant reads live from your governed model, and every figure traces to the source transaction.

Can we build our own agents on Cube?

Yes. Any agent framework that speaks MCP can query the governed model, and custom agents inherit the same access controls, audit trail, and lineage as Cube’s FP&Agents.

Who can use the Cube MCP Server today?

All Cube customers can use the Cube MCP Server; it’s generally available today. Your admins control who can connect an assistant and who holds write access.

What is MCP in finance?

MCP (Model Context Protocol) is an open standard that lets AI assistants connect to business systems through a common interface. Instead of copying data into a chat window, an assistant such as Claude, ChatGPT, Copilot, or Gemini requests the data it needs from an MCP server, and the server decides what it can see and do.

In FP&A, that means an assistant can answer questions on actuals, budgets, and forecasts, or write updates back to the plan, using the same governed model the finance team works in. Permissions, business rules, and the audit trail all come from the source system, not the chat.

Connect

One standard connection

Connect every MCP-compatible assistant once, instead of building and maintaining a separate integration for each AI tool.

Govern

Permissions carry over

Each user sees only the entities, accounts, and versions their Cube role allows, in every assistant.

Calculate

Figures of record

Answers come from Cube’s calculated model and business rules, so every assistant returns the same number.

Write back

Edits with approval

Assistants can propose plan and forecast updates that flow back to Cube for finance to review, with every change logged.

Why MCP matters for FP&A

AI assistants are already in use across most finance teams, often on exported spreadsheets that are out of date the moment they are downloaded and carry no permissions. MCP gives those assistants a governed path to live financial data. Finance keeps one source of truth, and the rest of the business gets answers in the tools they already use.

How to use MCP in FP&A

Rolling out MCP works best when the data foundation is already in place. A typical sequence:

  1. 1.
    Unify your financial data. Connect the GL, CRM, HRIS, and billing systems into one governed Cube model.
  2. 2.
    Set roles and permissions. Decide who can see which entities, departments, and plan versions.
  3. 3.
    Connect your assistants. Point Claude, ChatGPT, Copilot, Gemini, or another MCP client at the Cube MCP Server.
  4. 4.
    Start with read-only questions. Variance explanations, budget-to-actual checks, and KPI lookups are easy to verify.
  5. 5.
    Turn on write back. Let assistants submit forecast and plan changes for finance review and approval.
