finData MCP Server: Professional Financial Data Access for AI Applications

Overview: What is finData MCP Server?

finData is an open-source financial data inquiry Model Context Protocol (MCP) server, designed to provide advanced-level financial data access capabilities to machine learning models and AI applications. It supports various data sources such as Tushare, which empower users to swiftly integrate professional-grade financial information directly into their AI solutions.

🔧 Core Features & MCP Capabilities

finData serves as a universal adapter for AI applications, facilitating seamless connections with specific data sources through the standardized Model Context Protocol (MCP). This server ensures that advanced machine learning models can effectively interact and utilize diverse financial datasets from multiple suppliers. Key features include:

Versatile Data Sources: It supports multiple financial data providers such as Tushare.
Standardized Interface: MCP simplifies integration processes by providing a unified interface, ensuring compatibility across various AI applications.

⚙️ MCP Architecture & Protocol Implementation

The finData server is architected to seamlessly integrate with the Model Context Protocol (MCP), allowing for efficient communication between AI applications and financial data providers. The architecture involves multiple components working together:

MCP Client: A component that acts as a bridge, translating requests from an AI application directly into MCP-compliant commands.
Data Provider Interface: A standardized API that facilitates direct interaction with underlying data sources like Tushare.

🚀 Getting Started with Installation

To set up finData MCP Server, ensure the following prerequisites:

Python 3.11 or higher
mcp[cli] version 1.6.0 or above
pandas package version 2.2.3 or newer
Tushare package compatible with your Tushare API token

pip install python>=3.11 mcp[cli]>=1.6.0 pandas>=2.2.3 tushare>=1.4.21

Once the environment is ready, configure and start the finData MCP Server.

Configuration Example:

Use uv to run the finData MCP Server:

{
  "mcpServers": {
    "finData": {
      "command": "uv", 
      "args": [
        "--directory",
        "/ABSOLUTE/PATH/TO/PARENT/FOLDER/finData-mcp-server/src/findata", 
        "run",
        "server.py"
      ],
      "env": {
        "DATA_API_TOKEN": "",  // API token to access data providers
        "PROVIDER": "tushare"  // Data provider selected
      }
    }
  }
}

💡 Key Use Cases in AI Workflows

Real-World Use Case: Financial Trend Analysis for Investment Strategy

In this scenario, an investment firm uses finData MCP Server to gather historical financial data from Tushare. The AI application, powered by continue, queries the server to retrieve daily market trends and perform trend analysis.

{
  "query": {
    "dataSource": "tushare",
    "cmd": "daily",
    "args": [
      "--start_date", "2018-06-01",
      "--end_date", "2023-05-31"
    ]
  }
}

Real-World Use Case: Dynamic Pricing Strategy Management

Using finData in combination with Cursor, an e-commerce company can dynamically adjust pricing based on real-time market data. The AI application executes commands to fetch the latest stock prices and makes decisions on price adjustments.

{
  "query": {
    "dataSource": "tushare",
    "cmd": "daily",
    "args": [
      "--stock_code", "000651"
    ]
  }
}

🔌 Integration with MCP Clients

(finData) supports integration with popular AI clients such as:

Claude Desktop: Full support with API key configuration.
