How to Connect Claude to Your SEI Account Using Truthifi

Searching for "Claude SEI"? You're in the right place. SEI is one of the most significant advisor and institutional investment platforms in the world — managing $554.1 billion in assets under management and administering $1.29 trillion on behalf of wealth management organizations, private banks, RIAs, and institutional clients as of March 31, 2026. Whether you access the SEI Wealth Platform through SEI Advisor Center or work within a firm that runs on SEI's infrastructure, your managed account holdings, performance data, fee detail, and allocation history have been locked inside SEI's reporting environment. Until now, getting "Claude for SEI" meant exporting data, pasting it into Claude, and rebuilding context with every new conversation.

Truthifi changes that. With a Claude SEI connection using Truthifi, Claude can see your live SEI account holdings, performance, allocations, and fees through an Anthropic-supported MCP custom connector. Truthifi normalizes your data on connection: it stitches SEI account history from the BAA aggregation feed, resolves security-name inconsistencies, and fills timeline gaps so Claude reasons about reliable data, not raw exports. The connection is read-only, never stores your SEI Advisor Center credentials, and cannot move money, place trades, or alter any account or model.

This guide walks you through setup (about 5 minutes), what Truthifi allows and blocks with your SEI data, and the kinds of long-form analyses Claude handles especially well on institutional advisor platforms.

Before you begin, you'll need:

• A paid individual Claude subscription (Pro or Max). Custom connectors are only available on paid individual plans. Free accounts cannot add custom connectors.

• A Truthifi account with at least one linked financial institution.

2. What You Need

• Active SEI account with SEI Advisor Center or SEI Wealth Platform access

• Claude Pro plan ($20/mo) — required for custom MCP connectors

• MFA enabled on your SEI login

• Free Truthifi account at truthifi.com

• About 5 minutes for first-time setup

3. How to Connect Claude to Your SEI Account

Ready to connect Claude to financial accounts? Here's how to link Claude to your SEI profile using Truthifi.

1. Open Settings in Claude. Go to claude.ai. Click your profile → Settings → Connectors.

2. Add the Truthifi connector. Choose Add custom connector. Enter Name: Truthifi, MCP URL: https://api.truthifi.com/mcp. Click Connect.

3. Authorize your SEI accounts. Claude redirects you to Truthifi's OAuth screen. Sign in to your Truthifi account, choose SEI from the institution list, complete the BAA aggregator handoff with your SEI Advisor Center credentials plus MFA, and select which SEI accounts (managed accounts, brokerage accounts, retirement accounts, trust accounts, mutual funds, alternative investments) to share with Claude.

4. Enable Truthifi when needed. In any new chat, click + → Integrations → toggle Truthifi on. You may need to re-enable Truthifi in some new conversations if it isn't active by default.

5. Verify the connection. Send: "What is the total value across all my connected SEI accounts, broken out by account type and asset class?" If Claude responds with your actual SEI figures, you're live.

Your SEI account is now linked to Claude for live, read-only advisor-platform analysis.

4. Example Prompts for Claude

• Long-Form Portfolio Memo — "Pull all holdings across my SEI managed accounts. Write a 1,500-word memo covering asset-class allocation, the three largest single positions, how current allocation compares to stated targets, fee drag, and the top two things I should raise with my advisor at the next review."

• Performance Attribution Deep Dive — "Review my SEI account performance over the trailing 12 months and year-to-date. Write a structured analysis comparing each account to a relevant benchmark, breaking down what drove the gap — asset allocation, security selection, or fee drag — and what it implies for rebalancing."

• Fee Transparency Report — "Pull all advisory fees, fund expense ratios, and platform costs across my SEI accounts. Write a detailed breakdown by account, express the all-in cost in dollars and as a percentage of assets, and flag any account where total costs exceed 1.5% annually."

• Trust Account Review — "Analyze my SEI trust accounts in detail. Summarize the current value, asset mix, and performance. Flag anything in the allocation that looks unusual for a trust mandate — concentrated positions, illiquid alternatives, or asset classes that appear to drift from a typical fiduciary standard."

• Retirement Account Readiness Assessment — "Using the current value and allocation of my SEI retirement accounts (IRA, 401(k)), write a structured retirement readiness assessment. Estimate the projected value at ages 65 and 70 under conservative and moderate growth assumptions, and flag the two biggest risks to the plan."

• Alternative Investment Breakdown — "Pull all alternative investment positions in my SEI accounts. Explain what each one is, its role in the portfolio, its illiquidity profile, and whether the aggregate alternatives exposure looks appropriate relative to my overall asset mix."

• Drift and Rebalancing Memo — "For each SEI managed account, compare current holdings to target allocations. Identify every asset class drifted more than 3% from target. Write a rebalancing memo I could hand to my advisor with a recommended priority order and the dollar amounts that would need to move."

• Year-End Household Summary — "Aggregate all my SEI accounts into a household summary. Write a year-end report covering starting and ending total value, net contributions and withdrawals, performance vs. benchmark, fee paid for the year, and the most important portfolio action to take before year-end."

5. Why Truthifi?

5.1. Security

Your SEI Advisor Center username and password never touch Truthifi's servers. Authentication occurs through SEI's aggregator partner (BAA), creating a read-only, protocol-enforced connection secured with AES-256 encryption. Claude receives only scoped data tokens, never your SEI credentials. You maintain complete control and can revoke access anytime from your SEI Advisor Center settings or your Truthifi dashboard.

5.2. Privacy

Your financial data stays under your complete control when using Truthifi. We never store login credentials from SEI or any institution. You decide which specific SEI accounts Claude can see, with selective per-account permissions. Data is not sold to third parties, and connecting Claude does not grant access to any other AI you have connected through Truthifi.

5.3. Audit Trail

Every MCP data request is logged for Claude transparency. When Claude accesses your SEI data, the timestamp and specific data retrieved is recorded automatically. You maintain full visibility into which account details were accessed and when. Audit logs are available in your Truthifi dashboard.

5.4. Data Quality

SEI delivers raw account data through its aggregator partner. Security strings, allocation labels, and category tags can be inconsistent across accounts and reporting periods. Truthifi rebuilds that history from the aggregation source, normalizes security and ticker names, and stitches the timeline so Claude sees a clean, complete SEI picture.

6. About Claude

Claude, built by Anthropic, is a conversational AI especially strong at long-form reasoning, careful explanations, and structured writing — all of which map well to the complex, multi-account nature of an institutional advisor platform like SEI. The Claude Pro plan ($20/mo) is required to use custom MCP connectors. Free Claude accounts cannot add MCP connectors.

For SEI specifically, Claude is excellent at multi-step analyses — performance attribution memos, fee transparency reports, trust account reviews, and year-end household summaries. Claude tends to ask clarifying questions, show its work, and produce well-organized output. That thoroughness suits the kind of decisions SEI platform users often face: multi-account complexity, alternatives exposure, and fiduciary alignment across large household portfolios.

8. Frequently Asked Questions

Is it safe to connect my SEI account using Truthifi?

Yes. Your SEI login happens on SEI's own authentication screen through the BAA aggregator handoff. Your username and password never pass through Truthifi's servers. Claude receives only a scoped, read-only data token — it cannot move money, place trades, change models, or alter any SEI setting. Every data request is logged, and you can revoke access from your SEI Advisor Center or your Truthifi dashboard at any time. Full details at https://truthifi.com/security.

What can Truthifi actually do with my SEI data?

Truthifi pulls holdings, allocations, performance history, advisory-fee detail, and account metadata from your SEI accounts and exposes them to Claude through a read-only MCP connector. Claude can write performance attribution memos, calculate all-in fees, analyze trust and retirement accounts, and surface drift vs. targets. It cannot move money, place trades, or change SEI account settings.

Do I need a paid Claude plan to use this with SEI?

Yes. To use Claude with Truthifi, you need a Claude Pro subscription at $20/mo or higher. Custom MCP connectors are gated to paid Claude plans. Free Claude accounts cannot add the SEI integration.

Where is my SEI data stored?

Your holdings and performance data is fetched on demand from SEI's aggregator feed via Truthifi, used during the active Claude conversation, and not retained in Claude memory between sessions. Truthifi caches a normalized history so Claude has consistent context, and you can clear it from your dashboard at any time.

How do I disconnect Claude from Truthifi?

Open Settings → Connectors → find Truthifi → Disconnect. You can also revoke access from your SEI Advisor Center, or remove the institution entirely from your Truthifi dashboard. Disconnecting Claude does not affect any other AI you have connected through Truthifi.

How does Truthifi compare to other options for SEI?

What about my financial advisor or firm?

Claude does not replace your advisor or the wealth management organization running on SEI. Your advisor handles licensed guidance, model selection, suitability, and money movement. Claude — with read-only SEI data using Truthifi — helps you prepare for reviews, understand your allocation and fees, and ask better questions between meetings.

What SEI account types does Truthifi support?

Truthifi supports SEI managed accounts, brokerage accounts, retirement accounts (IRA, 401(k)), trust accounts, investment management programs, mutual funds, and alternative investments where they appear in the BAA aggregator feed.

Can Claude write a year-end portfolio memo using my SEI data?

Yes — and this is one of Claude's strengths. Claude can pull your full SEI household picture and produce a structured year-end memo covering total value change, performance vs. benchmark, fees paid, net contributions, and the most important actions heading into the new year.

How is Claude different from ChatGPT for SEI analysis?

Claude tends to write longer, more structured analysis and is more willing to show its assumptions — useful for trust account reviews, performance attribution, and fee transparency reports. ChatGPT tends to be faster and more conversational. Many users keep both: ChatGPT for quick lookups, Claude for deeper work.

Can I connect both Claude and ChatGPT to my SEI account?

Yes. Each AI connection using Truthifi is independent. Connecting Claude does not expose your SEI data to ChatGPT, and vice versa. You can revoke either at any time without affecting the other.

Does this replace the SEI Advisor Center?

No. The SEI Advisor Center and SEI Wealth Platform remain the systems of record for your accounts. Claude + Truthifi is for analysis and writing — it sits next to the platform, not in place of it.

Can Claude analyze my SEI alternative investment exposure in detail?

Yes. Claude can pull every alternative investment position in your SEI accounts, explain what each one is and its role in the portfolio, assess the aggregate alternatives weighting relative to your overall mix, and flag illiquidity or concentration risks — producing a structured writeup you could share with your advisor.

Is there a free Claude path for this?

No. Custom MCP connectors are gated to Claude Pro ($20/mo) or higher. If cost is a blocker, Truthifi also supports free or lower-cost AI clients (including OpenClaw), which you can use instead or alongside.

9. MCP Integration Paths

MCP (Model Context Protocol) is the open standard that lets Claude talk to external data sources through a structured, read-only interface. Anthropic, the company behind Claude, co-developed MCP, so Claude is one of the most natural homes for an MCP-based advisor-platform connector. When you connect Claude to SEI using Truthifi, you are using a Truthifi MCP server — infrastructure that translates Claude's natural-language requests into safe, scoped MCP API calls against your live SEI data.

Truthifi runs MCP servers across finance: MCP banking, MCP investment, MCP brokerage, MCP crypto. Each connector is read-only, protocol-enforced, and audit-logged. For SEI, the MCP investment integration covers managed accounts, trust accounts, retirement accounts, and alternative investments on the SEI Wealth Platform.

For developers, Truthifi's MCP API is documented for custom MCP integration work — building dashboards, internal tools, or routing SEI data into other MCP-aware clients. The same security model applies: no credentials, read-only scopes, full audit trail.
