How to connect Json Tools MCP
Json Tools MCP runs locally from a Node.js package published to the npm registry: json-tools-mcp version 1.0.0. It speaks MCP over stdio, so the client starts it as a program and talks to it through standard input and output. It needs Node.js; clients usually start it with npx — the usual command is npx -y json-tools-mcp@1.0.0.
In the mcpServers JSON format that many desktop and editor MCP clients read, the entry looks like this (placeholders in angle brackets):
{
"mcpServers": {
"json-tools-mcp": {
"command": "npx",
"args": [
"-y",
"json-tools-mcp@1.0.0"
]
}
}
