How to Connect Claude to Your Lighthouse Credit Union Account Using Truthifi

If you're a Lighthouse Credit Union member who has ever wished you could simply ask about your finances — "How much am I spending on dining out?" or "What's my net cash flow this quarter?" — Truthifi makes that possible with Claude. Lighthouse Credit Union is a member-owned, not-for-profit credit union serving members across New England, founded in 1936 and NCUA-insured. It offers checking and savings accounts, certificates (CDs) and money market, auto and personal loans, mortgages and home equity, credit cards, and IRAs — the full range of consumer banking products that New England members rely on.

Truthifi connects Claude to your Lighthouse CU accounts through a read-only MCP connector brokered by Plaid. Once connected, Claude can analyze your balances, categorize your spending, summarize your cash flow, review your certificate holdings, and answer natural-language questions about your money — using your actual Lighthouse Credit Union data, live and normalized. Claude never touches your online banking credentials and cannot transfer funds, pay bills, or change any account setting.

Setup takes about 5 minutes. Here's how.

2. What You Need

• Active Lighthouse Credit Union membership with online and/or mobile banking access enabled

• Claude.ai account (Pro plan recommended for the best experience with multi-account data)

• MFA (multi-factor authentication) enabled on your Lighthouse CU online banking login

• Free Truthifi account at truthifi.com

• About 5 minutes for first-time setup

5. Why Truthifi?

5.1. Security

Your Lighthouse Credit Union username and password never touch Truthifi's servers. Authentication flows through the Plaid aggregator handoff, creating a read-only, protocol-enforced connection secured with AES-256 encryption. Claude receives only scoped data tokens — never your Lighthouse CU online banking credentials. You can revoke access at any time from your Lighthouse CU settings or your Truthifi dashboard.

5.2. Privacy

You decide exactly which Lighthouse Credit Union accounts Claude can see. Truthifi never stores login credentials. You can share your checking and credit card accounts and exclude your savings, or connect everything — the granular controls are yours. Data is never sold to third parties, and connecting Claude does not automatically grant access to other AI tools.

5.3. Audit Trail

Every MCP data request Claude makes against your Lighthouse CU data is logged with a precise timestamp and a record of the specific information retrieved. You can review the complete audit log from your Truthifi dashboard. No silent background syncs — you see every query Claude ran.

5.4. Data Quality

Raw Plaid aggregator output for Lighthouse Credit Union accounts can include inconsistent merchant names, transaction description variations, and category-tagging gaps. Truthifi normalizes that data — cleaning merchant strings, resolving category mismatches, and filling timeline gaps — so Claude works with clean, reliable Lighthouse CU transaction data.

6. About Claude

Claude, built by Anthropic, is a conversational AI that excels at multi-step financial reasoning, detailed calculation, and producing structured summaries from months of raw transaction history. When connected to Lighthouse CU data through Truthifi, Claude can turn your transaction history into clean spending breakdowns, cash flow tables, and savings projections in plain English.

Claude's extended context window is particularly useful for Lighthouse Credit Union members with multiple account types — checking, savings, certificates, credit cards, and loans. Claude can hold your entire financial picture in context and let you drill from category totals into individual merchant details without losing the thread. Claude does not retain account details between sessions unless you explicitly share them.

7. About Lighthouse Credit Union

What can Claude actually see in my Lighthouse Credit Union accounts?

Claude can see account balances, transaction history (descriptions, amounts, dates), and account metadata — everything Plaid pulls from your Lighthouse CU accounts that Truthifi normalizes. Claude cannot see your credentials, initiate any transaction, or alter any account settings.

Do I need a paid Claude plan?

A Claude Pro subscription is recommended for the best experience with large transaction datasets and multi-step financial analysis. Truthifi's MCP connector is compatible with Claude.ai's integration framework.

Is Lighthouse Credit Union FDIC insured?

No. Lighthouse CU deposits are NCUA-insured, not FDIC. NCUA (National Credit Union Administration) provides equivalent federal deposit insurance protection for credit union members — up to $250,000 per member per ownership category.

Where is my Lighthouse Credit Union data stored when I use Claude?

Your data is fetched on demand during the active Claude conversation. Truthifi caches a normalized history under your account for consistency. You can clear it from your dashboard at any time.

How do I disconnect Claude from my Lighthouse Credit Union accounts?

Go to Claude Settings → Integrations → Truthifi → Remove, or remove Lighthouse Credit Union from your Truthifi dashboard. Disconnecting Claude does not affect other AI tools connected through Truthifi.

How does Truthifi compare to other options for Lighthouse Credit Union?

Can Claude transfer money or pay my Lighthouse CU bills?

No. Claude is entirely read-only through Truthifi. It can see your transactions and balances but cannot initiate any banking action. All transactions happen through Lighthouse Credit Union's own online banking or mobile app.

What Lighthouse Credit Union account types does Truthifi support?

Checking, savings, certificates (CDs), money market, auto loans, personal loans, mortgages, home equity, credit cards, and IRAs where they appear in the Plaid aggregator feed.

Can Claude help me plan a certificate ladder at Lighthouse CU?

Yes. Claude can list your current Lighthouse CU certificates with balances, terms, and maturities, and then propose a laddering strategy you could implement as each certificate matures. For rate details and new certificate openings, work directly with Lighthouse CU at lighthousecu.org.

How is Claude + Truthifi different from Lighthouse CU online banking?

Lighthouse CU's digital banking portal shows one account at a time in a static transaction format. Claude + Truthifi aggregates all your accounts simultaneously and lets you ask open-ended financial questions — spending patterns, savings trajectories, certificate maturities, loan-to-deposit ratios — the banking portal wasn't built to answer.

Can I connect both Claude and ChatGPT to my Lighthouse Credit Union account?

Yes. Each AI connection through Truthifi is independent. You control what each AI can see and can revoke any connection without affecting the others.

Does this replace Lighthouse CU online banking?

No. Online banking is the system of record for transactions, payments, and account management. Claude + Truthifi is an analysis layer that complements it.

Who can see my Lighthouse Credit Union data when I use Claude?

Only you, during an active Claude conversation with Truthifi enabled. Truthifi does not sell your data and does not share it with advertisers.

9. MCP Integration Paths

MCP (Model Context Protocol) is the open standard that lets AI agents like Claude talk to external financial data sources through a structured, read-only interface.
