How to connect Jarroba Tools

Jarroba Tools runs locally from a Node.js package published to the npm registry: @jarroba/mcp version 0.1.8. 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 @jarroba/mcp@0.1.8. It reads the environment variable JARROBA_MCP_DOMAINS; set it in the client's configuration for this server.

In the mcpServers JSON format that many desktop and editor MCP clients read, the entry looks like this (placeholders in angle brackets):

{
  "mcpServers": {
    "jarroba-tools": {
      "command": "npx",
      "args": [
        "-y",
        "@jarroba/mcp@0.1.8"
      ],
      "env": {
        "JARROBA_MCP_DOMAINS": "<value>"
      }
    }
  }
}
