Connect an MCP client

These are the commands and URLs the providers document. Use the paper or sandbox option first where one exists.

Robinhood

claude mcp add robinhood-trading --transport http https://agent.robinhood.com/mcp/trading
codex mcp add robinhood-trading --url https://agent.robinhood.com/mcp/trading

Both commands are from Robinhood’s onboarding page, which also lists other clients.1 Trading happens only in your Robinhood Agentic account.1

Coinbase

claude mcp add coinbase --transport http https://agents.coinbase.com/mcp
codex mcp add coinbase --url https://agents.coinbase.com/mcp

On the approval screen, select only the portfolio the agent should use.23

Webull (Cloud MCP)

codex mcp add webull --url https://api.webull.com/mcp

Other clients take https://api.webull.com/mcp as the server URL.4 Orders are prepared as instructions that you confirm in the Webull app.4

Interactive Brokers

Add a custom connector or remote MCP server with the URL https://api.ibkr.com/v1/api/mcp-public, then sign in through IBKR.5

Alpaca

Hosted (OAuth) servers for Claude Code, as documented by Alpaca:6

{
  "mcpServers": {
    "alpaca-trading": { "type": "http", "url": "https://api.alpaca.markets/mcp" },
    "alpaca-trading-paper": { "type": "http", "url": "https://paper-api.alpaca.markets/mcp" }
  }
}

The local v2 server runs over stdio with API keys; do not expose it to the internet.7

Common pitfalls

  • The agent previews but never orders. Coinbase documents this on some hosted reasoning modes; ask explicitly or use its CLI.2
  • Old tool names. Alpaca’s v2 server removed all v1 tools; start a fresh session after upgrading.7
  • Wrong environment. Check whether a local server defaults to sandbox or production.89
