You deploy the JSON MCP Server to query and manipulate JSON data through a standardized toolset. This server exposes powerful operations for JSONPath-based queries, filters, and a range of data transformations, making it easy for large language models to interact with JSON sources in a structured and repeatable way.

How to use

You use the server by running it in your environment and then sending requests through an MCP client. You can perform queries, apply filters, and execute a sequence of operations such as sorting, transforming, and aggregating data. Start with a JSON data source, then issue a query or filter to retrieve or refine the data, and combine multiple operations to shape your results. The tools expose common JSON data tasks in a consistent, scriptable form so you can drive JSON analysis from prompts or automation.

How to install

Prerequisites: you need Node.js installed on your system. Ensure you have npm or npx available in your shell.

# Using npx with specific version (recommended)
npx @gongrzhe/server-json-mcp@1.0.3

# Install specific version globally
npm install -g @gongrzhe/server-json-mcp@1.0.3

# Run after global installation
server-json-mcp

Additional setup

If you want to integrate with a desktop client, you can provide a configuration that runs the MCP server via a command. For example, you can configure a Claude Desktop JSON integration to execute the server with npx.

{
  "json": {
    "command": "npx",
    "args": [
      "@gongrzhe/server-json-mcp@1.0.3"
    ]
  }
}

Alternative runtime option

If you already have the package installed locally, you can start the server by invoking a Node entry point directly.

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

Available tools

query

Query JSON data using JSONPath syntax with extended operations. Input includes a URL to the JSON source and a jsonPath expression that can include various operations.

filter

Filter JSON data using conditions. Input includes a URL, a base jsonPath, and a filter condition to apply.
