Nelly the Elephant

Nelly the Elephant runs locally from a Node.js package published to the npm registry: nelly-elephant-mcp version 1.0.3. 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 nelly-elephant-mcp@1.0.3.

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

{
  "mcpServers": {
    "nelly-elephant-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "nelly-elephant-mcp@1.0.3"
      ]
    }
  }
}
