Short answer: Finviz does not publish an official MCP server. A community-built option exists, tradermonty/finviz-mcp-server, but it's unofficial, it requires your Finviz Elite key, and you're trusting a third-party project with that credential. Finviz's own developer access is the Elite Export/API, a rate-limited screener and fundamentals export for paying subscribers, not an open API or an AI-ready connector. If what you want is an AI assistant that can reason about your real money, meaning your bank, brokerage and crypto accounts, that's a job for Truthifi, not Finviz. Finviz helps you find stocks; it doesn't hold them.

What Finviz does

Finviz is a stock screener and financial-visualization website built for retail and active equity traders. It's a research tool: you use its screens, charts and maps to find stocks, scan for setups and compare fundamentals across the market. It is not a brokerage or a bank, and it doesn't hold your positions or your money. That distinction matters for the MCP question below, because it shapes both what an AI assistant could ever see through Finviz and what Truthifi can and can't bridge from it.

Does Finviz have an MCP server or API?

There is no Finviz-published MCP server. As of this review (2026), Finviz's own developer offering is the Elite Export/API, and its site doesn't list an MCP integration. If you search for one, what you'll find is a community/third-party project, tradermonty/finviz-mcp-server, built by an independent developer, not by Finviz. According to the project's public repository, it uses your Finviz Elite key to pull screener and fundamentals data into an MCP-capable assistant.

Treat that distinction seriously. An official server is built, maintained and secured by the provider that owns the data. A community server is maintained by whoever wrote it, on whatever schedule they choose, and when you install it you are typically handing it your Elite API key or credentials directly. With Finviz specifically, the key you hand over is the one tied to your paid Elite subscription, and Finviz has no say in how an independent developer's code stores, logs or transmits it. If you use a community MCP server for Finviz, treat the key you give it the way you'd treat any other credential you hand to an unaudited third-party tool, be deliberate about it, and know you can revoke and rotate that key if you need to.

On the official side, according to Finviz's Elite plan description (2026), the Export/API lets you export screener results and fundamentals data, and it's rate-limited. Finviz doesn't list a free public API tier, and Elite is a paid subscription; check Finviz's own pricing page for current rates rather than relying on third-party summaries. This is a data-export feature built for pulling screens and fundamentals programmatically, not an AI-assistant integration, and not a general-purpose API for arbitrary account or portfolio data, because Finviz doesn't hold your portfolio to begin with.

How to connect Finviz to an AI assistant today

Today there are two separate routes, and the one you need depends on the question you're asking. Screening and fundamentals go through Finviz's Elite Export/API or, if you accept the tradeoffs, the community server. Questions about what you own go through Truthifi, since your positions sit with your broker rather than your screener. The steps below cover both routes.

1. Split the job: screening questions versus holdings questions. "Screen for small-caps with insider buying" is a Finviz job, served by the Elite Export/API or the community MCP server if you accept its tradeoffs. "Am I already overweight semiconductors?" is a holdings job, and Finviz isn't where that data lives.

2. If you're using the community server, vet the repository before you connect a key. Open tradermonty/finviz-mcp-server and check the commit history for recent activity and the issue tracker for reports about key handling. Then find the code that reads your key: an environment variable you control is preferable to a key pasted into a config file you might share. Note which endpoints it calls, so you know where your key travels.

3. Get an Elite subscription if you don't already have one, since the official Export/API requires it.

4. For your bank, brokerage and crypto accounts, connect through Truthifi instead. Truthifi links those accounts read-only through Plaid, Yodlee or By All Accounts, so an MCP-capable assistant can read the balances and positions Finviz has no view of.

5. Ask your assistant about your connected accounts once Truthifi is linked, the same way you'd ask it to run a Finviz screen. If you ever want to cut the assistant off, the path is Connections → Agents → ⋯ → Revoke.

What You Can Ask

Once both routes are set up, the split shows up in the questions themselves. Through a community Finviz MCP server, if you choose to use one, you might ask things like "screen for stocks under $20 with a P/E below 15" or "pull fundamentals for the tickers on my watchlist." Through Truthifi, once your real accounts are connected, you can ask things like "what's my total exposure to tech stocks across my accounts?" or "what did I actually pay in fees last quarter?" Those are questions about money you hold, not stocks you're scanning.

With & Without Truthifi

The difference is easiest to see side by side.

Without Truthifi: your AI assistant can, at best, see Finviz screens and fundamentals data through a community server you've trusted with your Elite key, or nothing at all if you'd rather not take that step. It still can't see your actual brokerage balances, your bank accounts or your crypto holdings, because none of that lives inside Finviz.

With Truthifi: your AI assistant gets read-only visibility into the bank, brokerage and crypto accounts you connect, alongside whatever research tooling you run through Finviz. You get the screener for finding ideas and Truthifi for knowing what you actually hold and what it's costing you.

If screening is all you need from an assistant, the first setup may be enough, and stopping there is a reasonable choice. Truthifi earns its place the moment your question shifts from "what should I look at?" to "what do I already own?"

How Truthifi Can Help

That holdings gap is where Truthifi fits. Truthifi isn't a replacement for Finviz's screening and charting. It's the piece Finviz isn't designed to provide: a read-only, aggregated view of the accounts where your money actually sits. According to Truthifi's published platform figures (as of 2026), Truthifi connects to 18,000+ financial institutions through Plaid, Yodlee and By All Accounts and monitors $6B+ in assets. Your credentials don't pass through Truthifi: your login is entered with the aggregator, not with Truthifi, and Truthifi doesn't see or store it.

One honest caveat: Finviz itself isn't an aggregatable account. Nothing you own sits inside it, so there's no Finviz "account" for Truthifi to bridge in the way it bridges a brokerage. What Truthifi connects is the real accounts you hold elsewhere, the brokerage you execute trades in, the bank your cash sits in, the exchange that holds your crypto, so your AI assistant can see the full picture Finviz's screens are pointing you toward.

Once connected, paid Monitoring plans unlock fee breakdowns, benchmarks, and concentration and exposure views, on top of the baseline read-only account visibility. For how other research and brokerage providers handle AI access, see the Provider MCPs hub.

Truthifi is not an investment adviser and doesn't give investment, tax or legal advice.

FAQ

Does Finviz have an official MCP server? No. There is no Finviz-published MCP server. A community/third-party project, tradermonty/finviz-mcp-server, exists but is not built or maintained by Finviz.

Is the community Finviz MCP server safe to use? It's unofficial, which means you're trusting a third party's code and update practices, and it typically requires your Finviz Elite API key to work. Before connecting, check its commit history, its issue tracker and how it reads and transmits your key, as described in step 2 above.

Does Finviz have a free API? No. Finviz's Export/API for screener and fundamentals data is available to Elite subscribers and is rate-limited. There's no free public API tier.

Can Truthifi connect to my Finviz account? No, because Finviz is a screening and visualization tool, not an account that holds money or positions. Truthifi connects the real bank, brokerage and crypto accounts you hold elsewhere, read-only, so your AI assistant can see them alongside the research you do in Finviz.

Is my data safe if I connect accounts through Truthifi? Truthifi connects your bank and brokerage accounts read-only through Plaid, Yodlee or By All Accounts. Your login credentials are entered with the aggregator, never with Truthifi, and Truthifi never sees or stores them.
