Bring Your Own AI to Your Money: The Case for an Agentic Finance Tracker

Most financial apps stuff a generic chatbot into a sidebar. Hundo is an agentic finance tracking app built on MCP - connecting your actual ledger directly to Claude, ChatGPT, or the AI model you already use.

The Hundo team

Every personal finance app on the market seems to be racing to build the exact same feature: a cramped AI chat box shoved into their own sidebar.

You’re forced to use whatever model that company picked, inside the window they designed, answering questions based solely on whatever partial data they managed to scrape.

We took the exact opposite approach.

Hundo was built from the ground up as an agentic finance tracking app. Instead of building another walled-garden AI, Hundo speaks MCP (Model Context Protocol). You don’t visit a finance app to use a watered-down AI feature - you bring your full financial picture directly to the AI assistant you already rely on every single day.

What an "Agentic Finance Tracker" Actually MeansLink to this section

MCP is an open standard that lets AI clients safely read from and act upon external tools and data sources. Both Claude and ChatGPT speak it natively. Hundo runs an active MCP server at https://hundo.finance/mcp.

When you connect Hundo to your AI app, your entire ledger becomes something your AI model can actually reason about.

You aren't jumping back and forth between tabs or copying CSVs. You’re simply sitting in your normal ChatGPT or Claude workflow, and your net worth, cash flow, and daily spending become part of the context your AI understands.

It’s a subtle shift in architecture, but a massive leap in what you can actually do.

What You Can Ask Your AI Agent to DoLink to this section

Because Hundo supports full human-in-the-loop agentic workflows, your AI doesn't just display static charts - it actively manages your financial operations alongside you:

  • Log expenses in natural language: "I just paid 240,000 IDR in cash for dinner." Your AI formats the transaction and drafts a ledger entry.
  • Analyze real spending trends: "How much did I spend on ride-sharing over the last 90 days? Is that trending up compared to last quarter?" It queries raw, line-item ledger records - not pre-aggregated summaries.
  • Build realistic, context-aware budgets: "Look at what I actually spent on groceries and dining out over the past 6 months and draft a realistic budget for next month."
  • Perform deep net-worth audits: "Review my net worth movement over the last two quarters. What’s driving the growth, and where am I over-exposed?"
  • Handle complex, multi-currency actions: Log trades, track peer-to-peer IOUs, or reallocate account balances.

The Human-in-the-Loop Safety ModelLink to this section

An agentic personal finance app should never operate as a black box. Nothing gets written to your Hundo ledger automatically.

When your AI wants to record or edit something, it creates a staged proposal inside your conversation. You review the details, tell it to go ahead (or tell it what to tweak), and only then is the transaction committed to your ledger with a full audit trail behind it. If you ignore a proposal, it quietly expires.

The AI does the heavy lifting. You retain total authority.

Why Your Existing AI App Will Always Beat an App’s SidebarLink to this section

A chat widget inside a traditional budgeting app is frozen in time. Someone in a boardroom chose a model, wrote a system prompt, and set a hard token cap on response quality.

When you use an open, agentic framework like Hundo, your setup scales automatically:

  1. You choose the model: Want to use the highest-reasoning model available for a complex tax or portfolio question? Plug it in. That’s your choice, not a line item in a software company’s profit margin.
  2. Instant upgrades: When Anthropic or OpenAI ships a smarter model next month, your financial analysis gets smarter that minute. We don't have to push a single update.
  3. Unified life context: Your AI assistant already knows your career goals, the vacation you're planning, your tax bracket, and your writing style. Your money becomes dramatically more useful when analyzed alongside your entire life context - not trapped in an isolated finance tab.

Better Data Makes Better AgentsLink to this section

An AI agent is only as intelligent as the data it can access. This is where most AI money apps hit a wall.

Traditional budgeting tools rely entirely on bank aggregation APIs. Bank feeds are decent at pulling credit card transactions, but they're blind to everything else: cash in your drawer, physical assets, gold, crypto, foreign bank accounts, or private loans. For many people, that's where the majority of their actual net worth resides.

Hundo tracks everything:

  • Cash, bank accounts, and credit cards
  • Investments, stocks, crypto, and commodities
  • Real estate, vehicles, and illiquid assets
  • Multi-currency loans and personal IOUs
  • Seamless conversion across 160+ currencies with live conversion rates

Instead of feeding your AI agent a random stream of card charges, you hand it a structured, multi-currency, unified picture of your entire financial life.

The AI model is becoming a commodity. Your holistic financial data is not.

How to Set Up Your MCP Agentic Finance Server in 2 MinutesLink to this section

One server URL does it, and it is the same for every account:

https://hundo.finance/mcp

Nothing in that URL identifies you. Your account is attached when you sign in and approve access, which is the second half of the steps below. Settings has a copy button for it if you would rather not type it.

ClaudeLink to this section

  1. Open Settings in Claude.
  2. Go to Connectors in the left sidebar.
  3. Open the Add dropdown at the top right and choose Add custom connector.
  4. Fill in the two fields:
    • Name: Hundo Finance
    • Remote MCP Server URL: https://hundo.finance/mcp
  5. Leave the OAuth Client ID and Secret under Advanced settings empty. Hundo registers your client for you; those fields are for servers that make you create credentials by hand.
  6. Click Add. The connector appears with "You are not connected to Hundo Finance yet."
  7. Click Connect. Hundo opens in a new tab.
  8. Sign in if you are not already, then read the consent screen and click Approve. It spells out exactly what you are granting: read your financial data, and draft changes that it can only commit after you approve each one.
  9. You land back in Claude, and it confirms "Connected to Hundo Finance."

ChatGPTLink to this section

ChatGPT keeps custom MCP servers behind Developer mode, so there is one extra step at the front.

  1. Open Settings.
  2. Go to Security and login and find the Developer mode section.
  3. Turn Developer mode on. It is labelled "elevated risk" because it lets you add servers OpenAI has not reviewed. That is the price of connecting anything that is not on their built-in list, Hundo included.
  4. Open the plugins page at chatgpt.com/plugins.
  5. Click the + button at the top right, next to the search box.
  6. Fill in the form:
    • Name: Hundo Finance
    • Description: Hundo Finance MCP
    • Connection: leave it on Server URL (not Tunnel) and enter https://hundo.finance/mcp
    • Authentication: OAuth
  7. The advanced OAuth settings fill themselves in. ChatGPT reads them from Hundo's discovery document, so the auth, token and registration URLs, the scopes and the registration method (Dynamic Client Registration) all arrive on their own. You do not need to touch any of it.
  8. Two orange notices appear next to those settings: OIDC unavailable, and CIMD unavailable. Both are expected. They describe optional extras Hundo does not advertise, and neither is needed for this connection.
  9. Tick I understand and want to continue under the custom-server warning, then click Create.
  10. A card appears: Add Hundo Finance to ChatGPT. Click Sign in with Hundo Finance.
  11. You land on Hundo's approval screen, the same one described above. Click Approve.
  12. ChatGPT confirms the connection.

Any other MCP clientLink to this section

The shape is the same everywhere. Add a remote (Streamable HTTP) server pointing at https://hundo.finance/mcp, choose OAuth, let it open Hundo in a browser, and approve. There are no tokens to generate, copy or paste, and no credentials to create by hand: the client registers itself against Hundo's discovery document.

Check it workedLink to this section

Ask for something only your own ledger could answer:

Give me a detailed report of last month's finances and some suggestions, based on the data from Hundo.

If your real numbers come back, you are connected.

If it says it cannot see any Hundo tools, the server is added but not authorised, which is the step people skip. Reopen the connector and finish the sign-in and approval.

If it refuses with a message about Hundo Pro, the connection is fine and the plan is not: connecting your own AI is a Pro feature, free for everyone through September 30, 2026.

Honest Pricing & Zero Lock-inLink to this section

Connecting external AI agents via MCP is a Pro feature. Because we want everyone to experience what true agentic finance feels like, Hundo Pro is 100% free for all users through September 30, 2026.
