The JSON MCP server lets you efficiently interact with JSON data through an LLM, enabling you to split, merge, locate specific data, and validate JSON content against defined conditions. It’s lightweight, fast, and designed to be easy for your AI workflows to process JSON files directly.

How to use

You use the JSON MCP server by running it locally or via an executable command, then connecting your MCP client (such as an LLM-integrated tool) to perform tasks like splitting a large JSON into smaller objects, merging multiple JSON files into one, or querying for specific data within a JSON structure. Your client issues requests that trigger the server’s split, merge, find, and validate operations, and you receive structured JSON results suitable for further processing in your AI workflows.

How to install

Prerequisites: you need Node.js and npm installed on your machine. You will either install the MCP server globally or run it on demand with npx.

# Install the JSON MCP server globally
npm install -g json-mcp-server@latest

# Run after global installation
json-mcp-server

# Or use npx to run the latest version without installing globally
npx json-mcp-server@latest

Additional notes

Two primary ways to run the server are shown: a global installation command and an npx-based run command. You can also configure the server in development environments like VS Code or Claude Desktop where the CLI or GUI can start the MCP server using the same underlying npm/npx commands.

If you are configuring in an editor, you can supply the same runtime via the editor’s MCP integration, using the command npx with the argument json-mcp-server@latest to start the server.

Available tools

split

Split a JSON file into a specified number of objects, requiring a file path to locate the source JSON.

merge

Merge multiple JSON files from a folder into a single JSON file.

find

Find specific data within a JSON structure based on defined criteria.

validate

Validate JSON content against defined conditions or schemas.
