How to integrate Alpaca MCP with Codex
Connect Codex to Alpaca MCP. Show your current alpaca positions, check latest aapl market price, and more using natural language, with authentication handled for you.
Api KeyOauth2
Alpaca is a stock and crypto trading platform for commission-free trading, real-time market data, and algorithmic strategies. Use it to build brokerage apps, trading bots, and portfolio workflows with market connectivity.

Why use Composio?
Apart from a managed and hosted MCP server, you will get:
- CodeAct: A dedicated workbench that allows GPT to write its code to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling.
- Large tool responses: Handle them to minimise context rot.
- Dynamic just-in-time access to 20,000 tools across 1500+ other Apps for cross-app workflows. It loads the tools you need, so GPTs aren't overwhelmed by tools you don't need.
How to install Alpaca MCP in Codex
Run the setup command
Run this command in your terminal to add the Composio MCP server to Codex.
It will initiate the authentication in a browser window, authorize Codex to access your Composio account.
(Optional) Authenticate with OAuth
To authenticate manually, run the login command to open a browser window and authorize Codex to access your Composio account.
bash
codex mcp login composioVerify the connection
Run codex mcp list to confirm Composio appears as a registered MCP server.
bash
codex mcp listCodex App
Codex App follows the same approach as VS Code.
- Click ⚙️ on the bottom left → MCP Servers → + Add servers → Streamable HTTP:
- Fill the header and Key fields with
{ "x-consumer-api-key" = "ck_*******" }. - The Key is the Composio API key, that you can find on dashboard.composio.dev
- Click on Authenticate and authorize Codex to your Composio account and you're all set.
- Restart and verify if it's there in
.codex/config.toml
bash
[mcp_servers.composio]
url = "https://connect.composio.dev/mcp"
http_headers = { "x-consumer-api-key" = "ck_*******" }What is the Alpaca MCP server, and what's possible with it?
The Alpaca MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Alpaca account. It provides structured and secure access to your trading account and market data, so your agent can monitor positions, review orders, analyze portfolio history, manage watchlists, and track stock and crypto prices on your behalf.
- Account and portfolio monitoring: Have your agent review account details, open positions, portfolio history, account activity, and trading settings.
- Order and position management: Direct your agent to list filtered orders, cancel all open orders, or liquidate every open position at market price.
- Stock market research: Instruct your agent to retrieve historical price and volume bars for one or more stocks, check market hours, and review the trading calendar.
- Crypto market tracking: Let the agent fetch crypto quotes, historical bars, snapshots, order books, trades, and perpetual futures pricing for supported symbols.
- Watchlist management: Have your agent create watchlists and add stocks or crypto assets to existing lists by symbol or watchlist name.
Conclusion
You've successfully integrated Alpaca with Codex using Composio's MCP server. Now you can interact with Alpaca directly from your terminal, VS Code, or the Codex App using natural language commands.
Key benefits of this setup:
- Seamless integration across CLI, VS Code, and standalone app
- Natural language commands for Alpaca operations
- Managed authentication through Composio
- Access to 20,000+ tools across 1500+ apps for cross-app workflows
- CodeAct workbench for complex tool chaining
Next steps:
- Try asking Codex to perform various Alpaca operations
- Explore cross-app workflows by connecting more toolkits
- Build automation scripts that leverage Codex's AI capabilities

FAQ
Frequently asked questions
With a standalone Alpaca MCP server, the agents and LLMs can only access a fixed set of Alpaca tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Alpaca and many other apps based on the task at hand, all through a single MCP endpoint.
Yes, you can. Codex fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Alpaca tools.
Yes, absolutely. You can configure which Alpaca scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.
All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Alpaca data and credentials are handled as safely as possible.
