JSON MCP Server - Enhancing AI Application Integration Through MCP Protocol

Overview: What is JSON MCP Server?

The JSON Model Context Protocol (MCP) server, implemented in this project, serves as a powerful adapter layer for JSON-based data interaction with artificial intelligence applications. By adhering to the MCP protocol, it enables seamless communication between AI tools and various JSON data sources, effectively bridging the gap between complex data formats and intelligent model requirements.

🔧 Core Features & MCP Capabilities

The core features of the JSON MCP Server include robust querying and manipulation capabilities, which are essential for integrating data-intensive applications with AI models. The server is designed to handle standardized input parameters such as URLs, JSONPaths, conditions, array operations, string transformations, date manipulations, numeric calculations, and aggregation metrics, all adhering to the Model Context Protocol.

Components & Operations

Tools: The server provides essential tools for data manipulation:
- Query Tool: Allows querying of JSON data using JSONPath syntax with extended operations. It supports URL as input and a JSONPath expression that can include various operations.
- Filter Tool: Provides filtering capabilities based on conditions, involving URL, base JSONPath, and filter conditions.
Supported Operations: A wide range of operations are supported to manipulate the JSON data:
- Array Operations: Slicing ($[0:5], $[-3:], $[1:4]), sorting ($.sort(price)), distinct values ($.distinct()), and transformations like map, flatten, union, intersection.
- String Operations: Case manipulation ($.toLowerCase(), $.toUpperCase()), string tests ($.startsWith('test'), $.endsWith('test')), and search functions ($.contains('test'), $.matches('pattern')).
- Numeric Operations: Mathematical operations like addition, subtraction ($.math(+10), $.pow2()), rounding ($.round(), $.floor(), $.ceil()), and function application.
- Date Operations: Date formatting ($.format('YYYY-MM-DD')), date checks ($.isToday()), and date modifications ($.add(1, 'days')).
- Aggregation Operations: Grouping data by categories ($.groupBy(category)), and statistical aggregations like sum, average, minimum, maximum.

⚙️ MCP Architecture & Protocol Implementation

The JSON MCP Server is built to follow the Model Context Protocol (MCP) specifications, ensuring compatibility with various AI applications. The architecture is designed to abstract away the complexities of interacting directly with JSON data, allowing developers and model integrators to leverage standardized protocols for seamless data access.

Building from Source

To integrate this server into your project or run it stand-alone:

Clone the repository

git clone https://github.com/gongrzhe/json-mcp-server.git

Install dependencies
```
npm install
```
Build the project
```
npm run build
```

These steps ensure that you have a local copy of the server ready for testing or deployment.

🚀 Getting Started with Installation

For quick and easy integration, follow these steps:

Using npx with specific version (recommended)
```
npx @gongrzhe/[email protected]
```

Install specific version globally

npm install -g @gongrzhe/[email protected]

After installation, simply run:

server-json-mcp

💡 Key Use Cases in AI Workflows

Scenario 1: Financial Analysis for Investment Models

Imagine an investment model using historical financial data to predict trends and make informed decisions. By integrating the JSON MCP Server with tools from this dataset, the server can be used to filter recent transactions, calculate average transaction amounts, and identify top spenders, all while adhering to the Model Context Protocol.

# Example command for filtering and summing up recent transactions
npx @gongrzhe/[email protected] -u https://finance.api.example.com/data -j "$..transactions[*].amount" --sum | sort -nr -k2

Scenario 2: Customer Behavior Analysis

In customer behavior analysis, real-time data from logs or CRM systems need to be processed for insights into customer preferences and behaviors. The JSON MCP Server can filter relevant log entries based on conditions like date ranges or specific events.

# Example command for filtering relevant log entries within the past month
npx @gongrzhe/[email protected] -u https://logs.api.example.com/data -j "$..events[*]" --startsWith "Login" --isToday | sort -nr -k2

These workflows leverage the extensive operations and standardized protocols of MCP to deliver scalable and efficient data processing solutions.

🔌 Integration with MCP Clients

The JSON MCP Server is compatible with several AI applications, including Claude Desktop. To set up your environment:

Configuration Example for Claude Desktop

Add this configuration snippet to your claude_desktop_config.json file:

{
  "mcpServers": {
    "finance": {
      "command": "npx",
      "args": ["@gongrzhe/json-mcp-server", "-y"]
    }
  }
}

Alternatively, for node.js users:

{
  "mcpServers": {
    "finance": {
      "command": "node",
      "args": ["path/to/build/index.js"]
    }
  }
}

This setup ensures that Claude Desktop can seamlessly interact with the JSON MCP Server to fetch and manipulate data according to your predefined workflows.
