Stock Market Data MCP server

This MCP server provides stock data services for querying and analyzing stock information. Built on Spring Boot and Spring AI, it offers real-time trading data, time-series price information, and company details for stocks in the Shanghai and Shenzhen markets (for learning MCP server concepts).

Technology Stack

• Java 21
• Spring Boot 3.4.4
• Spring AI 1.0.0-M7
• Maven
• Lombok

Features

• Real-time stock trading information queries
• Time-series price data retrieval
• Company detailed information lookup
• Support for stocks in both Shanghai and Shenzhen markets

System Requirements

• JDK 21 or higher
• Maven 3.6.0 or higher

Installation Guide

Building the Project

1. Ensure you have JDK 21 and Maven installed
2. Clone the repository or download the source code
3. Build the project using Maven:

mvn clean package

This will create a JAR file in the target directory named stock-mcp-0.0.1-SNAPSHOT.jar.

Configuration

Setting Up in Cursor

1. Open File -> Preferences -> Cursor Settings -> MCP
2. Click "Add new" to add a new configuration
3. Copy the following content into the mcp.json file:

{
  "mcpServers": {
    "stockServer": {
      "command": "C:/Path/To/Your/JDK21/bin/java.exe",
      "args": ["-jar", "Path/To/Your/Project/target/stock-mcp-0.0.1-SNAPSHOT.jar"]
    }
  }
}

4. Update the command path to your actual JDK 21 installation location
5. Modify the jar path in args to point to your actual compiled JAR file location

Usage Guide

After configuration, you can ask the large language model questions about:

• Real-time stock trading information
• Stock time-series price data
• Detailed company information
• Current time information

Example Queries

You can ask questions like:

• "What is the current price of BABA stock?"
• "Show me the price chart for AAPL for the last week"
• "Tell me about the company information for Tesla"
• "What are the current trading volumes for major tech stocks?"

The MCP server will process these requests and return the relevant stock information through the AI interface.

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "stockServer" '{"command":"C:/Users/Administrator/.jdks/ms-21.0.6/bin/java.exe","args":["-jar","E:/IdeaProjects/stock-mcp/target/stock-mcp-0.0.1-SNAPSHOT.jar"]}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "stockServer": {
            "command": "C:/Users/Administrator/.jdks/ms-21.0.6/bin/java.exe",
            "args": [
                "-jar",
                "E:/IdeaProjects/stock-mcp/target/stock-mcp-0.0.1-SNAPSHOT.jar"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "stockServer": {
            "command": "C:/Users/Administrator/.jdks/ms-21.0.6/bin/java.exe",
            "args": [
                "-jar",
                "E:/IdeaProjects/stock-mcp/target/stock-mcp-0.0.1-SNAPSHOT.jar"
            ]
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
