before you install - you'll need

TONNODE_KEYS

Environment variables documented in the project's README - it lists which are required and which have defaults.

Claude Code

claude mcp add tonnode-mcp -- npx -y @tonnode/mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "tonnode-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@tonnode/mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key
