Adding to Claude Desktop via JSON

Ensure you have Claude Desktop installed.

Open or create the Claude configuration file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

Windows: %APPDATA%\Claude\claude_desktop_config.json

Linux: ~/.config/Claude/claude_desktop_config.json

Add the mcp server to your configuration:

{
    "mcpServers": {
        "multiversx-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "@multiversx/mcp"
            ],
            "env": {
                "MVX_NETWORK": "devnet",
                "MVX_WALLET": "absolute/path/to/someWallet.pem"
            }
        }
    }
}

Adding to cursor

The same JSON configuration from above works for Cursor (version >= 0.47). Add the config in the ~/.cursor/mcp.json config file. Or alternatively, go to Cursor Settings -> MCP section, then add a new MCP.

Build from source

Clone the repository, then run npm run build.

In the config file, set the server to the one you've just built.

{
    "mcpServers": {
        "multiversx-mcp": {
            "command": "node",
            "args": [
               "absolute/path/to/index.js"
            ],
         "env": {
            "MVX_NETWORK": "devnet",
            "MVX_WALLET": "absolute/path/to/someWallet.pem"
          }
        }
    }
}
