Searching for “OpenClaw Vanguard”? You’re in the right place. Your Vanguard account holds your financial life: checking balances, investment positions, retirement savings. Until now, getting “AI for Vanguard” meant exporting CSVs, copying numbers, and hoping nothing was stale by the time you asked a question.
By Scott Blandford, Founder & CEO of Truthifi | Reviewed by Mike Young
Truthifi changes that. With an OpenClaw Vanguard connection using Truthifi, OpenClaw can see your live Vanguard portfolio data, balances, and transaction history. Truthifi rebuilds your historical data on connection: it fills gaps, corrects cost basis errors, and resolves ticker mismatches, so OpenClaw works with clean, normalized data from day one. All of this happens through a read-only MCP connector that never touches your credentials and cannot move money.
This guide walks you through setup (about 5 minutes), explains exactly what Truthifi allows and blocks with your Vanguard data, and shows you how to turn raw financial data into actionable Vanguard AI insights with OpenClaw.
Before you begin, you'll need:
A working OpenClaw installation. OpenClaw is open-source and self-hosted — you'll need it running on your own machine, server, or container. See docs.openclaw.ai for installation.
Either the mcporter skill (recommended path) — install via
npm install -g mcporter— or comfort editing the OpenClaw config file directly at~/.openclaw/openclaw.json.A Truthifi Connect account with at least one linked financial institution. Truthifi Connect is free to try, with paid plans from $5.99/month.
Plan note: OpenClaw itself is free and open-source — no subscription tier required on the OpenClaw side. Truthifi Connect's free tier is enough to get started.
Reverse-proxy gotcha: If your OpenClaw instance runs behind a reverse proxy (Caddy, nginx, Cloudflare Tunnel, etc.), set the MCP_ISSUER_URL environment variable to your public HTTPS URL. Otherwise the OAuth metadata advertises localhost and authentication fails silently.
What You Need
Before connecting OpenClaw to Vanguard, you'll need a working OpenClaw installation (open-source and self-hosted; see docs.openclaw.ai), either the mcporter skill or comfort editing OpenClaw's config file directly, and a Truthifi Connect account with at least one linked financial institution. Truthifi's free tier is enough for personal use.
How to Connect OpenClaw to Your Vanguard Account
Connecting OpenClaw to Vanguard takes one of two paths: the mcporter skill (recommended) or direct config-file edit. Both register Truthifi as an MCP server that OpenClaw can call.
Install the mcporter skill (or prepare the OpenClaw config file). Path A (recommended): Run npm install -g mcporter to install the mcporter skill globally. Path B (direct config): locate ~/.openclaw/openclaw.json — you'll edit it manually. Either path requires a working OpenClaw installation; see docs.openclaw.ai for setup.
Register Truthifi as an MCP server. Path A: Run mcporter search truthifi to confirm Truthifi is in the registry, then mcporter install --target openclaw truthifi. Path B: Edit ~/.openclaw/openclaw.json and add Truthifi to the mcpServers block: {"mcpServers": {"truthifi": {"type": "http", "url": "
https://api.truthifi.com/mcp"}}}, then save and restart the OpenClaw gateway.Authorize your accounts. The first OpenClaw call to Truthifi triggers the OAuth flow in your browser. Sign in to your Truthifi account, select which Vanguard accounts to share with OpenClaw, confirm the read-only scope, and click Authorize.
Confirm reverse-proxy config (if applicable). If your OpenClaw instance runs behind a reverse proxy (Caddy, nginx, Cloudflare Tunnel, etc.), set the MCP_ISSUER_URL environment variable to your public HTTPS URL — otherwise the OAuth metadata advertises localhost and authentication fails silently.
Verify the connection. Ask OpenClaw via your channel of choice (web, Discord, Telegram): "Use Truthifi to show my current asset allocation." If OpenClaw responds with your actual Vanguard holdings, the connection is live across all OpenClaw channels.
Truthifi is now registered as an MCP server in your OpenClaw instance. Across web, Discord, Telegram, or any other channel you've configured, OpenClaw can pull live Vanguard data on request. No per-conversation toggle — once registered, the connector is always available.
Example Prompts for OpenClaw
Portfolio Deep Dive
Pull my complete asset allocation across all my Vanguard accounts and break it down by asset class, sector, and geography. Format the results as a table with dollar amounts and percentages for each category.
Fee Audit
Calculate the total expense ratios, advisory fees, and any other costs I'm paying across every fund and account in my Vanguard portfolio. Show me the dollar amount per year for each fee layer and the cumulative impact over 10 years assuming 7% annual growth.
Retirement Readiness
Run a retirement readiness analysis using my current Vanguard balances, contribution rate, and historical savings trajectory. Model three scenarios — conservative, moderate, and optimistic — and tell me at what age each scenario runs out of money. Present the results as a comparison table.
Stress Test
Stress-test my entire Vanguard portfolio against a 2008-style market crash, a 2020-style rapid drawdown, and a sustained stagflation environment. Show projected drawdown percentages and estimated recovery timelines for each scenario.
Tax-Loss Harvesting
Identify every tax-loss harvesting opportunity in my Vanguard taxable accounts. For each position with an unrealized loss, estimate the tax savings at a 24% federal bracket and suggest a replacement holding that maintains similar sector exposure.
Cash Flow Analysis
Analyze my spending and cash flow from my Vanguard transaction history over the past 6 months. Categorize expenses into fixed, variable, and discretionary. Calculate my savings rate and flag any months where I spent more than I earned.
Rebalancing Plan
Compare my current Vanguard portfolio to a standard 60/40 target allocation and to a three-fund lazy portfolio. For each comparison, show me where I'm overweight and underweight, and recommend specific rebalancing moves with dollar amounts.
Holdings Review
Review my top 10 holdings by portfolio weight and run a fundamental analysis on each — P/E ratio, dividend yield, 52-week performance, and analyst consensus. Flag any positions where concentration exceeds 10% of my total portfolio.
Account Overlap Check
Analyze the overlap between my Vanguard brokerage account and my retirement accounts. Identify any duplicate holdings, correlated positions, or sectors where I have unintentional concentration risk across accounts.
Financial Dashboard
Summarize my complete financial picture across all connected Vanguard accounts — total net worth, investment performance over the past 1, 3, and 5 years, total fees paid last year, and my current savings rate. Format this as an executive financial dashboard.
Why Truthifi?
Security
Your Vanguard username and password never touch Truthifi's servers. Authentication occurs directly on your provider's domain, creating a read-only, protocol-enforced connection secured with AES-256 encryption. OpenClaw receives only scoped data tokens, never your actual credentials. You maintain complete control and can revoke access anytime at Vanguard's connected apps settings or through your Truthifi dashboard.
Privacy
Your financial data stays under your complete control when using Truthifi. We never store login credentials from Vanguard or any financial institution. You decide which specific accounts OpenClaw can access, creating selective permissions rather than blanket access. Data never gets sold to third parties, and connecting one AI tool doesn't automatically grant access to others.
Audit Trail
Every MCP data request is logged with complete session details for OpenClaw financial planning transparency. When OpenClaw accesses your Vanguard account data, the timestamp and specific information retrieved gets recorded automatically. You maintain full visibility into which financial details were accessed during each interaction. This tracking means you always know exactly what happened with your sensitive financial information.
Data Quality
When Vanguard delivers raw transaction data with 730 days, Truthifi rebuilds historical information from multiple aggregation sources to correct these inconsistencies. Our normalization process fills data gaps and resolves ticker mismatches that could mislead OpenClaw financial planning algorithms. This process delivers up to 10 years of clean, accurate transaction history for reliable analysis.
About OpenClaw
OpenClaw is an open-source, self-hosted AI agent runtime. Unlike hosted assistants (ChatGPT, Claude, Perplexity, Grok), OpenClaw runs on your own infrastructure — server, container, or laptop. Connected to Truthifi via MCP, OpenClaw uses your live Vanguard data while keeping the model interaction itself fully under your control. This is a strong fit for teams that won't send financial data to hosted services.

Frequently Asked Questions
Is it safe to connect my Vanguard account using Truthifi?
Connecting through Vanguard's OAuth 2.0 flow ensures your login credentials stay exactly where they belong: on Vanguard's own secure servers. When you connect, you're redirected to Vanguard's domain to log in directly, then grant specific read-only permissions before returning to Truthifi. Your username and password never pass through our systems. OpenClaw receives only a scoped data token with read-only access, meaning it cannot move money, execute trades, or modify account settings. Every data request is logged for transparency, and you maintain full control through Vanguard's connected apps settings or our dashboard. Complete security details at https://truthifi.com/security.
What does Truthifi allow with my Vanguard data — and what does it block?
When you connect OpenClaw to financial accounts, the AI cannot move money, place trades, or change account settings due to architectural limitations. The read-only access token from OAuth 2.0 flow prevents OpenClaw from executing any transactions on your Vanguard account. Instead, OpenClaw personal finance capabilities focus on surfacing your fee burden across funds, flagging allocation drift from your target, and modeling retirement scenarios using your actual contribution rate.
Financial advisors provide guidance based on your full financial picture, while AI analysis supplements your understanding between professional meetings.
What about my financial advisor?
The relationship between Vanguard advisors and OpenClaw creates a support system for your financial planning needs.
What Vanguard account types does Truthifi support?
Truthifi supports connecting your Vanguard Brokerage Accounts, IRAs, 401(k) Plans, 403(b) Plans, Pension Plans accounts through its read-only MCP connector. Each account type is linked with the same security architecture — no trading, no transfers, no changes to your Vanguard settings. You can connect multiple account types simultaneously for a complete financial picture.

How do I disconnect OpenClaw from Truthifi?
To disconnect OpenClaw from Truthifi: Path A — run mcporter uninstall --target openclaw truthifi (if installed via mcporter). Path B — edit ~/.openclaw/openclaw.json, remove the truthifi entry from mcpServers, save, restart the gateway. Either path stops OpenClaw from querying Vanguard data immediately.
Your OpenClaw Vanguard connection through Truthifi represents a new way to interact with your own financial data. No exports, no stale spreadsheets, no guesswork. Just your live OpenClaw Vanguard portfolio view, analyzed whenever you have a question. Check your investment performance, run AI stock analysis, review fees across accounts, model retirement scenarios, or simply ask OpenClaw to explain what changed since last month.
Because the data refreshes automatically using Truthifi's read-only connector, every answer reflects your current balances, holdings, and transaction history — not a snapshot from days or weeks ago. Whether you manage a single brokerage account or coordinate across multiple financial institutions, the combination of OpenClaw and Truthifi puts real portfolio intelligence when you need it.
As OpenClaw evolves, the financial insight it can extract from your Vanguard data will only deepen. This connection puts you closer to your own financial data. Privacy is central to the design: Truthifi never stores your credentials, and the read-only protocol means no AI assistant can execute transactions on your behalf. You stay in full control of what data is shared and can revoke access at any time through your account settings.
The result is financial transparency without financial risk — your data, your questions, on your schedule.
Congratulations! With your Vanguard account now connected through Truthifi, OpenClaw can analyze your real portfolio data in real time. Track your investments, review your fees, and ask questions about your actual financial accounts. Your data flows using Truthifi's read-only MCP connector — OpenClaw can see your data but cannot make trades, move funds, or alter your account settings in any way.
Start with a simple question like 'What is my current asset allocation?' or 'How have my investments performed this year?' to see the connection in action. From there, you can explore deeper analyses specific to your financial goals. As you continue using OpenClaw with your Vanguard data, you may discover patterns in your spending, identify underperforming holdings, or find opportunities to reduce fees across your portfolio.
Each conversation builds on the last, giving you progressively richer financial awareness. The more questions you ask, the more value this connection delivers.
Is connecting my Vanguard account using Truthifi safe?
When you connect Vanguard to OpenClaw, your login happens directly on your bank's secure domain through their official authentication system for OpenClaw financial planning.
What can Truthifi actually do with my Vanguard data?
With OpenClaw, you can analyze your Vanguard portfolio allocations to identify concentration risks across multiple investment accounts.
Do I need a paid OpenClaw plan?
No paid plan required on the OpenClaw side — OpenClaw is free, open-source, and self-hosted. You pay for whatever compute you run it on (laptop, server, cloud VM), not for OpenClaw itself. Truthifi has free and paid plans starting at $5.99/month; the free tier covers most personal-portfolio use cases for Vanguard.
Where is my data stored?
Depends on your OpenClaw configuration. By default, OpenClaw queries Vanguard data through Truthifi's MCP connector at conversation time and the data flows through reasoning context for that single chat. However, OpenClaw is self-hosted and configurable — your specific deployment may log conversation context to disk. Review your OpenClaw logging settings if persistent storage of financial data is a concern. Truthifi maintains the canonical encrypted record independent of OpenClaw.
How do I enable the OpenClaw connection with Truthifi?
OpenClaw's MCP connector model is different from hosted assistants — once Truthifi is registered in ~/.openclaw/openclaw.json, OpenClaw has access across all channels by default. There's no per-conversation toggle to re-enable. To temporarily restrict access, use OpenClaw's auth/permission settings to scope which users or channels can invoke Truthifi.
Does this replace my financial advisor?
No, connecting Vanguard through Truthifi does not replace your financial advisor. The platform offers data analysis, not advisory services, while OpenClaw supplements advisors between meetings with account insights.
What is Truthifi?
Truthifi serves as an independent financial data platform that enables you to connect OpenClaw to financial accounts from over 18,000 US institutions. The service operates on a subscription model and does not sell data, earn commissions, or sell financial products. Through secure MCP integration, OpenClaw can access your Vanguard accounts and other holdings for AI financial planning purposes.
Who can see my data?
No external parties can access your Vanguard account information when using OpenClaw for finance. Only OpenClaw receives your data during active conversations, and we maintain a subscription model that never involves selling your financial information to third-party companies.
Informational only. Not financial advice. Consult a qualified financial advisor before making investment decisions. Truthifi is an independent platform. This guide reflects current product functionality as of May 2026.
