Meta Muse can connect directly to your Public.com brokerage account, giving the AI agent access to real-time market data, your portfolio, and trading capabilities through Public’s MCP server.
Once connected, you can use natural language to research markets, check your portfolio, analyze options, and trade stocks, ETFs, options, and crypto from a Muse conversation.
This guide covers how to connect Meta Muse to Public and what you can do once the connection is active.
Public’s Model Context Protocol (MCP) server connects Meta Muse to Public’s trading infrastructure. Instead of using Muse only to research an investment, you can use the same conversation to access market and account data and prepare or execute supported trades.
With Public connected, you can ask Meta Muse to:
This effectively turns Muse into a conversational interface for Public’s trading API.
You’ll need a Public brokerage account, a Meta Muse account, and a Public API key.
Create or sign in to your Meta Muse account and start a new conversation.
Give Muse the Public MCP server address:
https://mcp.public.com/mcp
You can use the following prompt:
The Public.com MCP server is at https://mcp.public.com/mcp. Authenticate using my Public API key as the Bearer token in the Authorization header. Connect via MCP streamable HTTP (POST an initialize request first), then use the check_setup tool to verify it worked. Use my key only for this session, and never place trades without my explicit confirmation.
Generate an API key from your Public API settings and provide it to Muse when prompted.
Your API key should be treated like a password. It can provide access to account information and trading functionality, so it should only be shared with applications you trust and should never be posted publicly.
Once connected, ask:
List my Public.com accounts.
Muse should return the Public accounts accessible through your API credentials.
For detailed setup instructions, see the Public Meta Muse MCP documentation.
Once connected, Muse can combine conversational AI with live information from your Public account and Public’s API.
For example:
“Show me my current positions, buying power, and today’s portfolio performance.”
Or:
“Show me the current price and today’s performance for AAPL, BTC, and SPY.”
You can continue asking follow-up questions within the conversation rather than moving between a brokerage app, market-data tools, and an AI assistant.
Muse can also retrieve your open orders, recent transactions, dividends, interest earned, and account history.

Muse can use Public MCP to prepare and place supported equity orders using natural-language instructions.
For example:
“Buy $500 of NVDA.”
“Buy 10 shares of AAPL with a limit price of $200.”
“Show me my open orders and cancel my open TSLA limit order.”
Public supports both fractional and whole-share equity trading. Eligible U.S. equities can also be traded 24 hours a day, five days a week through the API.
For an extended-hours trade, you could ask:
“Prepare an extended-hours limit order to buy 5 shares of AAPL at $200. Show me the preflight details and wait for my confirmation.”
Public MCP also gives Muse access to options market data and trading functionality.
You can start by asking:
“Show me the options chain for AAPL contracts expiring next Friday.”
From there, Muse can retrieve contracts by expiration date, strike and option type, as well as access available options data and Greeks.
For example:
“Show me the delta, gamma and theta for the AAPL $250 call expiring next Friday.”
You can then prepare a trade and review its preflight details before submitting the order.
Public’s API supports native multi-leg options orders, allowing Muse to work with strategies that contain multiple contracts as a single order.
That includes strategies such as vertical spreads, straddles and iron condors.
For example:
“Build an iron condor on SPY expiring in two weeks. Show me the legs, current pricing and preflight details before placing the trade.”
The available strategies and trades depend on the options permissions associated with your Public account.
Stocks and options aren’t the only assets available through the connection. Public MCP can also access supported crypto trading through the same Muse conversation.
For example:
“What is the current price of ETH?”
Or:
“Prepare an order to buy 0.25 ETH at market price and show me the order details before submitting it.”
This allows you to access multiple asset classes through one conversational interface instead of maintaining separate AI-to-broker integrations.
Connecting Meta Muse to Public brings research, portfolio information, market data, and trade execution into the same AI workflow.
Public’s API provides read and write access across stocks, ETFs, options, index options, bonds, and crypto, along with real-time pricing, historical market data, options chains, advanced order types, and 24/5 trading for eligible equities.
For traders using AI agents, that means a conversation can move from:
Research → market data → portfolio context → trade construction → preflight → execution
without requiring a separate custom trading integration.
Public’s API is free to access, and API trades are commission-free, although regulatory and other applicable fees may still apply. Eligible stock and ETF options trades may also earn Public’s API options rebate.
