How to Connect Merrill Edge to an AI Assistant

Connecting Merrill Edge to an AI assistant means giving an assistant like ChatGPT or Claude permission to see your real holdings, so its answers are about your actual portfolio instead of hypothetical examples. The AI does not log into Merrill Edge directly. Instead, a secure aggregator sits in the middle: you authenticate through the broker's own flow, the aggregator receives scoped, read-only access, and the AI tool reads your positions through the aggregator.

The key word is read-only. Merrill Edge is Bank of America's self-directed brokerage, and third-party AI connections to it are primarily for tracking and analysis rather than trade execution. Aggregator coverage of Merrill Edge can also be limited, so a Merrill Edge connection may not be available in every tool, and where it is available it tends to be read-focused. That makes Merrill Edge a candidate for AI-driven analysis and tracking, and not a reliable path for AI-routed trades. Always confirm current support in the tool you choose before you rely on it. To have an assistant place approved trades, you would use a broker that documents execution support through an aggregator, such as E*Trade, Public, tastytrade or Webull, and verify what is available first.

There are three practical ways to get your Merrill Edge holdings in front of an AI assistant, ordered here from most capable to least. Each depends on Merrill Edge being currently supported by the tool you use.

• 1. A portfolio-aware MCP connector. A Model Context Protocol connector exposes your supported brokerage account to Claude Desktop, ChatGPT, or Cursor, so the assistant itself can read your positions live. The connector links the broker securely and read-only, with your login staying at the broker. Walnut offers a portfolio-aware MCP connector that works this way. Best if you already work inside an AI client. Confirm Merrill Edge coverage before relying on it.
• 2. A purpose-built AI investing app. A hosted app links your supported account securely and adds an assistant you talk to, with no code. You log in at the broker, the app reads your holdings read-only, and you ask questions through Claude, ChatGPT, or a built-in assistant. Best for most people. Walnut works this way too. Check that Merrill Edge is in the supported broker list.
• 3. Manual copy-paste. You paste a list of your Merrill Edge holdings into ChatGPT or Claude by hand. It works for a one-time snapshot and needs no broker connection at all, but prices go stale immediately, you have to keep re-pasting, and long lists invite arithmetic mistakes. Fine for a quick look, weak for ongoing analysis, and useful as a fallback if aggregator support for Merrill Edge is not available.

Across all three, the read-focused caveat for Merrill Edge holds: the AI can read and analyze, but you should not assume it can trade on Merrill Edge through a third-party connection, and you should confirm whether the broker is supported at all. For a deeper comparison of connector options, see the best MCP connectors for brokerages.

Walnut connects supported brokers securely, so your broker login is never stored by Walnut and the access stays read-only. Where Merrill Edge is supported, the flow takes a few clicks:

1. Create a Walnut account and open the brokerage-connection screen.
2. Check the broker list. Look for Merrill Edge among the supported brokers and confirm it is currently available before continuing.
3. Log in at the broker. The connection opens the broker's own authentication flow, so your password is entered at the broker and never seen by Walnut.
4. Authorize read access. The connection is read-only, which is what analysis needs and what third-party AI connections to Merrill Edge are designed for.
5. Start chatting. Ask about your holdings, performance versus the S&P 500, or concentration, through Claude, ChatGPT, or Walnut's built-in assistant.
6. Revoke any time. Disconnect the broker from Walnut's connections screen, or revoke the authorization from your Merrill Edge or Bank of America security settings, and the access stops.

Because the connection is read-only, Walnut treats a connected Merrill Edge account as a tracking-and-analysis source. If Merrill Edge is not currently supported by your tool, the manual copy-paste route still lets you analyze a snapshot of your holdings. If you also want an AI to place approved trades, connect a broker that documents execution support alongside it, and confirm what is available first. If you prefer to stay inside your own AI client, you can use Walnut from there by adding its MCP server URL, https://walnutinvest.com/api/connector/mcp, as a custom connector in Claude, ChatGPT, or Codex, then signing in with a free Walnut account and approving read-only access (it never places trades). The full per-client setup lives on the Walnut MCP connector page.

Once Merrill Edge is connected read-only, the assistant can answer questions about your real positions instead of hypothetical ones. Useful prompts include:

• “How is my Merrill Edge portfolio doing versus the S&P 500?” Each holding framed against a benchmark, as a window return rather than realized profit and loss (broker feeds rarely pass cost basis).
• “Where am I most concentrated?” Which positions dominate the account and how lopsided the mix is.
• “Which of my holdings are lagging?” Relative performance across your positions, surfaced in plain language.
• “What themes does my Merrill Edge account lean into?” Whether your holdings cluster around AI, semiconductors, or another theme.
• “Explain why this position moved.” Context on a specific ticker you hold, pulled from live data and the wider web.

The assistant reads and analyzes. It does not place trades on Merrill Edge, because the connection is read-only. You can ask about a specific stock or a theme you want exposure to, framed against your real holdings.

This is the caveat that separates Merrill Edge from brokers that document execution support. Through third-party brokerage connections, a Merrill Edge connection is best treated as read-only: it is designed for tracking and analysis, not for routing trades. Coverage of Merrill Edge can also be limited, so the connection may not be available in every tool. Do not assume an outside assistant can place orders on Merrill Edge, and confirm current support before you rely on either reading or trading.

Merrill and Bank of America separately offer their own digital and research tools inside their own products. That is a different thing from connecting Merrill Edge to an outside assistant like ChatGPT or Claude. The honest summary is: connect Merrill Edge to an outside AI for tracking and analysis where it is supported, and use a broker that documents trade execution if you want an assistant to place approved orders, verifying availability in both cases.

It can be safe, and the read-only nature of the connection helps. The security model rests on three things. First, credential handling: through a regulated brokerage connection, your Merrill Edge login is entered at the broker's own authentication flow and is never stored by the AI tool. Second, scope: the connection is read-only, so the assistant can see your positions but cannot move money. Third, control: you can revoke the connection at any time, from the app's connections screen or from your Merrill Edge or Bank of America account security settings.

The pattern to avoid is any tool that asks for your Merrill Edge password directly rather than routing you through the broker's own login. The Model Context Protocol, the open standard introduced by Anthropic in late 2024, was designed around scoped, permissioned access, which fits a read-only Merrill Edge connection well. Confirm the tool uses a regulated brokerage connection, confirm the access is read-only, and confirm you can revoke it before you connect. For a fuller treatment, see is it safe to connect your brokerage to an AI.

To connect Merrill Edge to an AI assistant: pick a tool that uses a regulated brokerage connection, create an account, check that Merrill Edge is in the supported broker list, log in through the broker's own flow, and authorize read access. From there you ask Claude, ChatGPT, or a built-in assistant about your real holdings. With Walnut, the same connection also works as a portfolio-aware MCP connector if you prefer to stay inside Claude Desktop. The connection is read-only throughout, so the AI analyzes rather than trades, and you should confirm Merrill Edge support before relying on it.

Here are the main options, listed so you can compare them. To be upfront, since this is our site, Walnut is one of them, and it is not crowned overall. Each depends on Merrill Edge being currently supported, so check the broker list in whichever you pick:

• PortfolioPilot. Connects your accounts read-only and returns a structured critique with a risk read. Best for a written second opinion on the whole portfolio.
• Walnut. An AI investing assistant that talks to the broker you already have and places the trades you approve. Where the broker is supported, Walnut connects it securely and read-only, so you can analyze your real Bank of America self-directed holdings through Claude, ChatGPT, or Walnut's built-in assistant, with your login staying at the broker. It is also a portfolio-aware MCP connector if you prefer to stay inside Claude Desktop. Walnut is not an investment adviser.
• Magnifi. A conversational assistant for natural-language questions about funds and holdings. Best for research and fund discovery in plain English.
• Mezzi. Aggregates several investment accounts into one view with a tax-aware lens. Best for tax-aware tracking across accounts.
• SnapTrade. A brokerage connection product that some apps and developers use to link supported US brokers to outside tools through a secure, read-only authentication flow. Named here as one of the underlying connectors people compare; Merrill Edge coverage can be limited.

Because Merrill Edge coverage can be limited, confirm the current supported-broker list in whichever tool you pick. For the wider field, see the best AI portfolio analyzers roundup, or the guide to the best AI investing app.

You connect Merrill Edge to an AI assistant through a secure brokerage connection, where support exists, so your real holdings reach ChatGPT or Claude and the assistant's answers are about your actual portfolio. The caveat that matters: Merrill Edge is Bank of America's self-directed brokerage, third-party AI connections to it are read-focused for tracking and analysis rather than trading, and coverage can be limited, so confirm current support before you rely on it. Walnut connects supported brokers securely and lets you analyze your real holdings through Claude or ChatGPT, read-only and revocable at any time. If Merrill Edge is not supported in your tool, manual copy-paste still lets you analyze a snapshot. Walnut is not an investment adviser.

The connection is to Walnut, and the assistant then reads Walnut, so the same setup works in every client that supports remote MCP servers rather than needing a separate integration each time. The server URL is:

Merrill Edge accounts are commonly linked to a wider banking relationship, so it is worth confirming which registrations came through. Every question below is answered against the positions in the account rather than from general knowledge.

Portfolio analysis

• “How has my Merrill Edge account done against the S&P 500 this year?”
• “What share of it sits in my single largest holding?”

Research

• “What does my largest holding actually do, and why might it have moved this week?”

Cost

• “What is my weighted average expense ratio across this account?”

Rebalancing

• “How far has each position drifted from its target weight?”

Planning a purchase

• “If I added $500 to this idea, would I be more concentrated or less?”
