Codex connects to Robinhood’s agentic trading as a streamable HTTP MCP server. You can add it from settings or the CLI. Same endpoint either way.
Before you start
You need a Robinhood individual investing account in good standing, on a desktop device — the only place you can open an agentic account and authenticate. Decide your funding amount first; it’s the hard ceiling on what your agent can lose.
The Robinhood Trading MCP URL:
https://agent.robinhood.com/mcp/trading
Connect Codex
From settings:
- Go to Settings → MCP servers.
- Select the Streamable HTTP option.
- Add the MCP link:
https://agent.robinhood.com/mcp/trading
Or from the CLI:
codex mcp add robinhood-trading --url https://agent.robinhood.com/mcp/trading
Complete authentication when prompted, then open and fund your Agentic account. Robinhood handles the auth flow.
Set guardrails before Codex trades
A connected agent with no limits is pointed straight at your money. Before the first order:
- Generate a guardrail config with the free SecProve Agent Safety Kit and load it as a standing instruction — caps, an approval gate, a kill switch, and a prompt-injection rule.
- Set your spending and trade limits.
- Know your kill switch — the "STOP" phrase and how to remove the MCP server.
Good to know
Agentic trading is in beta and equities-only right now. Robinhood does not monitor or audit connected agents — the safety configuration is yours to own, so set it before you trade.
Adding the server is a one-liner. Knowing whether Codex can be tricked into ignoring its limits is a security skill — and it’s measurable. Test yours at secprove.com.
