What is Banking Assistant?
Banking Assistant is a working MCP App built on Metabind, the hosted platform for MCP Apps. Ask a question about money and the answer comes back as an interactive card instead of a paragraph of numbers: net worth over time, where the money went, recurring charges, individual transactions, and trend charts.
It uses sample data for a fictional personal-finance app. No account or API key is needed.
Tools
| Tool | Type | What it does |
|---|
net_worth_trend | UI | Net worth and account balances over a period, as a line or bar chart |
spending_breakdown | UI | Spending split by category for a period |
subscriptions | UI | Recurring charges with the total monthly cost; flags new or repriced charges |
transaction_list | UI | Individual purchases for a category or merchant |
trend_card | UI | Any metric over time, built from the data tools |
get_net_worth | Data | Net worth history and account balances |
get_spending_breakdown | Data | Categorized spending with a prior-period comparison |
get_subscriptions | Data | Recurring-charge detection |
get_transactions | Data | Raw transactions by category or merchant, about 12 months of history |
All tools are read-only.
Try it
Add the endpoint to any MCP client that supports MCP Apps, such as Claude or ChatGPT:
https://mcp.metabind.ai/IgJH0BzIn4LlfnCbcDc7/projects/GLbHk5i3GLlIYcF63XFl
Then ask:
- "How is my net worth trending this year?"
- "Where did my money go last month?"
- "Which subscriptions went up in price?"
- "How much did I spend on dining over the last 6 months?"
Clients without MCP Apps support can still call the four data tools and get the numbers as text.
How it's built
The cards are BindJS components. BindJS is an open-source (Apache 2.0) component language for agent UI. Metabind hosts the MCP server, validates each tool call against its schema, and renders only the components you approved.
The same components render as native SwiftUI on iOS and Jetpack Compose on Android through the Metabind Assistant SDK, so one MCP App serves Claude, ChatGPT, and your own apps. The iOS and Android demo apps are open source in metabindai/metabind-demos.
Build your own
Metabind turns the components and APIs you already have into a hosted MCP App. Start free or read the getting started guide.
