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

5 objects per file
mergeMerge JSON files into a one JSON file

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.
