The Model Context Protocol (MCP) server empowers LLMs to efficiently interact with JSON files. With JSON MCP, you can split, merge, and find specific data, validate within JSON files based on defined conditions.
✅ Fast and lightweight
✅ LLM-friendly functionality
Below is a demo showcasing the split functionality:
splitSplit a JSON file into a specified number of objects.
Note: The file path must be provided.
Prompt Example:
Split JSON file from /Users/json-mcp/tests/merged.json
5 objects per file
mergeMerge JSON files into a one JSON file
Note: The folder path should be provided
Prompt Example:
Merge json files from /Users/json-mcp/tests
To configure the JSON MCP server manually in VS Code, update the User Settings (JSON) file:
{
"mcp": {
"servers": {
"json-mcp-server": {
"command": "npx",
"args": ["json-mcp-server@latest"]
}
}
}
}
You can install the JSON MCP server using the VS Code CLI:
# For VS Code
code --add-mcp '{"name":"json-mcp-server","command":"npx","args": ["json-mcp-server@latest"]}'
After installation, the JSON MCP server will be available for use with your GitHub Copilot agent in VS Code.
To install json-mcp for Claude Desktop automatically via Smithery:
npx -y @smithery/cli install @VadimNastoyashchy/json-mcp --client claude
npm install -g json-mcp-server@latest
json-mcp-server
npx json-mcp-server@latest
Generate boilerplate files, apply templates, create project structures
Example
Create React component with tests and styles, generate OpenAPI spec, scaffold new project
Eliminate repetitive file creation work

💡 Pro Tips
Architecture
MCP server provides file I/O operations (read, write, search, metadata) as tools Claude can invoke with natural language instructions.
Protocols
Compatibility
✓ Use when
Use for code analysis, file organization, content search, template generation, and automating repetitive file operations. Best for local development workflows.
✗ Avoid when
Avoid for system-critical files, sensitive credentials, production environments, or when file integrity is paramount. Don't use on files you can't afford to lose.
