Public
Self-described as the world first agentic brokerage (March 31, 2026) with in-app AI Agents and a public trading MCP server.
Public called itself the world's first agentic brokerage on March 31, 2026. It embeds AI Agents inside the app, and also exposes a trading MCP server at mcp.public.com/mcp (Claude, Perplexity, ChatGPT) covering stocks, ETFs, options, crypto, and bonds with live data.
Safety model: every Agent must be approved by you before it goes live, and can be edited, paused, or shut down anytime. For MCP trading, Public's disclosure notes trades may execute "without your direct input on each transaction." Dedicated accounts for AI workflows, real-time trade confirmations, and an authenticated brokerage environment are part of the design; no third-party API keys are required.
