> Give Claude Desktop the Hanzo toolset: `hanzo-mcp` in claude_desktop_config.json. Claude Code has its own page.

## Hanzo MCP

Claude takes Hanzo's tools one way, **Local**: `hanzo-mcp` on your machine, started with `npx -y hanzo mcp` (needs Node.js). With no key set it uses the sign-in `hanzo login` stored, so there is no key to paste ([MCP](https://docs.hanzo.ai/docs/mcp)).

Claude takes a key only through request headers, which are a limited beta in its connector screen.

Claude Desktop: open `Settings > Developer > Edit Config`, then add to `claude_desktop_config.json`.

```json
{
  "mcpServers": {
    "hanzo": {
      "command": "npx",
      "args": ["-y", "hanzo", "mcp"]
    }
  }
}
```

Claude Desktop reads `claude_desktop_config.json` from `~/Library/Application Support/Claude/` on macOS, `%APPDATA%\Claude\` on Windows and `~/.config/Claude/` on Linux. An app started from the Dock or the Start menu does not read your shell's PATH: if it cannot find `npx`, write the full path `which npx` prints as the `command`.

claude.ai in the browser reaches remote servers only, from Anthropic's cloud, so the local server runs in Claude Desktop. Claude Code, in the terminal and the IDE extensions, is [its own page](https://docs.hanzo.ai/docs/guides/coding/claude-code).
