Short answer: Finnhub is a market-data source, not an account you hold money in, so there's nothing in it for an AI to "see" about your finances — only quotes, fundamentals and reference data it can look up. As of this writing there's no official Finnhub MCP server to confirm. If you want your AI to reason about your actual positions alongside market data, Truthifi connects to the bank and brokerage accounts you actually hold, and that's the piece Finnhub was never built to provide.

This matters because people searching for a "Finnhub MCP" are usually trying to solve two different problems at once: getting market data into their AI workflow, and getting their AI to understand their own money. Finnhub can help with the first. It was never designed for the second.

What Finnhub Does

Finnhub is a market-data and financial-API provider. It supplies things like stock, forex and crypto quotes, company fundamentals, earnings data, and other reference datasets that developers and analysts pull into dashboards, trading tools and research workflows. It is not a brokerage, bank, or custodian, and it does not hold customer funds or securities. There is no "Finnhub account" in the sense of a balance, a holding, or a transaction history belonging to you — there's a developer/API account used to pull data, which is a different thing entirely.

That distinction matters for anyone thinking about AI access: Finnhub has data about the market. It has no data about your portfolio, unless you've separately told it what you own.

Does Finnhub Have an MCP Server or API?

Finnhub is known primarily as an API provider for market data. As of this writing, there is no official Finnhub MCP server to point to. If one exists or is released, the setup steps below would need to change to reflect it. We are not asserting Finnhub has published an MCP server, and we're not asserting it hasn't published any API at all — only that we have no confirmed, sourced official MCP server to describe here.

If you're integrating Finnhub's data today, that typically happens through its existing developer API rather than an MCP-native connector, but confirm current availability directly with Finnhub before building anything that depends on it.

Setting Up AI Access: What's Actually Possible Today

Because there's no confirmed official Finnhub MCP server, "setup steps for connecting Finnhub via MCP" isn't something we can responsibly walk through yet. What we can walk through is the setup that actually gets your AI assistant looking at real financial data today — your own accounts, via Truthifi:

1. Create a free Truthifi account. This is the layer that gives your AI something real to reason about: your own balances, holdings and transactions, not just market quotes.

2. Link your bank and brokerage accounts to Truthifi. You do this through Truthifi's aggregation partners, not through Finnhub. Your login credentials are entered with the aggregator, never with Truthifi.

3. Review what Truthifi surfaced. Truthifi runs its checks against your linked accounts, including fee visibility, concentration and exposure review, and more, depending on your plan.

4. Connect your AI assistant to Truthifi. In Connections → Agents, authorize the agent you want to use. The button to confirm is Authorize.

5. Ask your AI about your real accounts. From here your assistant can reference your actual positions, not just general market data it might otherwise pull from a source like Finnhub.

6. Revoke anytime. Go to Connections → Agents → ⋯ → Revoke if you want to disconnect an agent.

What You Can Ask

Once your AI assistant has access to your real financial accounts through Truthifi, the questions change shape. Instead of "what's the current quote on this stock," you can ask things that blend market context with your actual exposure:

• "How much of my portfolio is concentrated in the sectors I follow most closely?"

• "If this stock I'm watching moves 10%, how does that affect my actual holdings?"

• "What are my real holdings and balances across the accounts I've linked?"

• "Where do my positions overlap with the names I track for market data?"

A tool like Finnhub can tell your AI what a stock is doing. It can't tell your AI what you own. That gap is exactly where the second kind of question above lives.

With Finnhub Alone vs. With Finnhub + Truthifi

With Finnhub alone: your AI assistant can be grounded in market data — quotes, fundamentals, reference datasets — but it has no visibility into your actual accounts. It can discuss a stock's price action in the abstract; it can't tell you how that price action affects your real portfolio, because it was never given access to your real portfolio in the first place.

With Finnhub and Truthifi together: your AI can combine market awareness with an actual, current view of your bank and brokerage accounts, linked through Truthifi. Market data and your real financial picture sit side by side, so your assistant can connect general market movement to your specific exposure instead of treating the two as unrelated.

How Truthifi Can Help

Truthifi doesn't connect to Finnhub, and it doesn't need to. Finnhub is a data vendor, not a financial account, so there's no account data there for Truthifi to aggregate. What Truthifi does instead is give your AI assistant read-only visibility into the financial accounts you actually hold, the banks, brokerages and other accounts you choose to link. That gives your assistant a real foundation to reason from, with or without a market-data layer like Finnhub sitting alongside it.

That's the Partner-Complement Principle at work: Finnhub stays excellent at what it does, which is market data. Truthifi fills the part Finnhub was never meant to fill, which is your actual financial picture. Truthifi is not an investment adviser and doesn't give investment, tax or legal advice.

Frequently Asked Questions

Does Finnhub have an official MCP server? Not as of this writing, to our knowledge. If that changes, this guide should be updated to reflect the current state.

Can my AI see my portfolio through Finnhub? No. Finnhub provides market data, not account data. It doesn't hold your balances, holdings or transactions, so there's nothing for an AI to retrieve from Finnhub about your personal portfolio.

Does Truthifi connect directly to Finnhub? No. Truthifi reaches your real financial picture by connecting directly to the banks and brokerages you link, not through Finnhub.

Is this read-only? Yes, for the bank and brokerage accounts you connect through Truthifi. Truthifi's read-only scope applies to those linked accounts.

What if Finnhub releases an MCP server later? Then it would be worth evaluating for pulling market data into an AI workflow. It still wouldn't give an AI visibility into your actual holdings, which is the gap Truthifi is built to close.
