MCP Server demo for Market news

This MCP server is a wrapper around some finnhub.io API calls for retrieving market status and market news. It is a very simple demo but it is enough to get started around MCP servers using the Java SDK of the model context protocol.

Requirements

• Java 21 or greater
• Maven
• Claude Desktop (free plan)
• Finnhub account (free plan)

Installation

• mvn clean package
  

• Add a configuration for Claude Desktop
  • Windows or Mac (https://modelcontextprotocol.io/quickstart/server#windows)
  • Add the following into the claude_desktop_config.json file:

    •   {
          "mcpServers": {
              "US_stock_market_status": {
                  "command": "java",
                  "args": [
                    "-jar",
                    "<PATH-TO-JAR>"
                  ],
                  "env": {
                    "FINNHUB_API_TOKEN": "<INSERT-TOKEN>"
                  }
              }
          }
        }
      

• Restart Claude Desktop, and enable this tool.
• Example prompts:
  • Give me the latest market news.
  • Give me the latest market news. Just 1 new and give priority to the news related to the attacks between Israel and Iran.
  • Give me the top 3 latest market news with their reference urls and the original headlines.
