What is the Alpaca Trading MCP Server?

This is an intermediate service that connects AI assistants with the Alpaca securities trading platform, adopting the Model Context Protocol (MCP) standard protocol. It allows AI assistants like Claude to query account information, obtain market data, and execute trading operations, interacting with the Alpaca platform just like human traders.

How to use this service?

You need to first configure the MCP server information in the Claude client, and then you can query accounts, view market quotes, or issue trading instructions through natural language commands. All operations will be executed in the Alpaca paper trading environment through a secure API channel.

Applicable scenarios

Suitable for users who wish to conduct securities trading operations through natural language or for developers who want to test AI trading strategies. All trades are executed in the paper trading environment by default, avoiding real - money risks.

Main Features

Account information queryObtain key information such as the balance and positions of the Alpaca trading account in real - time.
Market quote dataQuery the latest quotes and historical price data (last 7 days) of stocks.
Intelligent trading executionIssue trading operations such as market orders/limit orders through natural language commands.
Portfolio managementView the current positions and recent trading records.

Advantages and Limitations

Advantages
Conduct securities trading through natural language without programming knowledge.
Use the Alpaca paper trading environment by default to ensure fund security.
Support for standardized protocols and can be integrated with other MCP - compatible tools.
