Integration

Alpaca Trading API integration

Alpaca is an API-first broker for US stocks, ETFs, options and crypto. Read the account (buying power, equity, positions, activities, portfolio history), place, replace and cancel orders, close positions, exercise options, look up tradable assets and option contracts, read the market clock and calendar, and manage watchlists. On a live account an order buys or sells real securities with real money; a paper account simulates it. Left out: the activity event stream (SSE), the deprecated corporate-action announcements, short-sale locates, tokenization minting (authorized participants only), and the crypto funding wallets, transfers and withdrawal whitelists. Authentication is an API key pair sent as the APCA-API-KEY-ID and APCA-API-SECRET-KEY headers; the connection also picks paper-api (paper trading keys) or api (live keys).

What you can do with Alpaca Trading API

Each of these is one operation on one endpoint, available both as a workflow step and as a tool an AI agent can call on its own. Nothing bundles several operations into one action, so what a run did stays readable afterwards.

Use Alpaca Trading API from Claude Code, Cursor or Codex

Connect Alpaca Trading API in LiveContext, create an API key in Settings, then add the LiveContext MCP server to your client. Its Alpaca Trading API operations become tools the client can call, next to every other integration you connected.

Claude Code

claude mcp add --transport http livecontext https://livecontext.ai/mcp --header "X-API-Key: YOUR_API_KEY"

Codex (~/.codex/config.toml)

[mcp_servers.livecontext]
url = "https://livecontext.ai/mcp"

[mcp_servers.livecontext.http_headers]
"X-API-Key" = "YOUR_API_KEY"

Cursor, Claude Desktop and other JSON configs

{
  "mcpServers": {
    "livecontext": {
      "type": "http",
      "url": "https://livecontext.ai/mcp",
      "headers": {
        "X-API-Key": "YOUR_API_KEY"
      }
    }
  }
}
