ChatGPT and Claude

360marketview has its own MCP server. Connect it once, and ChatGPT or Claude can answer questions about your portfolio with the numbers 360marketview calculated, not guesses: what you hold, what it is worth, how it did against the S&P 500, what is coming up for the companies you own.

1. 1You ask“How did my portfolio do this year?”
2. 2ChatGPT or Claudepicks the tools it needs:get_performance
3. 3360marketviewanswers from your own trades and today's prices
4. 4The answerquotes your numbers: +18.4% vs the S&P 500's +14.1%

The figures in step 4 are an example.

What MCP is

The Model Context Protocol is the standard way AI apps connect to other services. ChatGPT and Claude both support it. When you ask a question, the app decides which of 360marketview’s tools it needs, calls them, and writes its answer from what they return. You never call a tool yourself, and you can see in the chat which ones it used.

What you can ask

• “How did my portfolio do this year against the S&P 500?”
• “Which of my stocks report earnings in the next two weeks?”
• “Have insiders been selling anything I own?”
• “Is NVDA expensive against its own history and its sector?”
• “Make a watchlist of my three biggest losers and alert me if any of them moves 5% in a day.”

More, by topic, in Example questions. Every tool the apps can use is in Tools.

Two levels of access

You choose one when you connect. It cannot be changed later; make a new connection instead.

	Read only	Read and manage
Your portfolios, holdings, trades, cash and performance	Reads	Reads
Any stock: prices, financials, valuation, analysts, insiders, Congress	Reads	Reads
Your watchlists and the stocks on them	Reads	Creates, adds, removes
Notes on a stock’s chart, with a reminder	—	Writes
Alerts	Reads	Creates, pauses, resumes, deletes
Trades, cash, your account	Never	Never

Read only is the default. With Read and manage, ChatGPT and Claude ask you before each change, and everything they make is labelled in the app with an Undo. See Changes and safety.

Who can use it

Today, every account can connect during its free trial or plan. Once packages go on sale, ChatGPT and Claude connections will be part of Pro, and every new account will still start with 7 days of everything. See Plans and trial.

Your numbers stay 360marketview's

The apps quote what 360marketview calculated from your own trades. The server tells them not to recalculate shares, cost, profit or returns, and to say so when a figure is missing rather than estimate it. Nothing here is investment advice.
