## How to connect it

Runs on your machine over stdio, launched by your MCP client.

### Claude Code

```sh
claude mcp add optuna -- npx -y <package-from-readme>
```

Swap in the exact package and flags from the repo README — most servers need an API key passed as an environment variable. Add `--scope user` to make it available in every project.

### Claude Desktop

Open **Settings → Developer → Edit Config** and add the server to `claude_desktop_config.json`, then restart Claude Desktop:

```json
{
  "mcpServers": {
    "optuna": {
      "command": "npx",
      "args": [
        "-y",
        "<package-from-readme>"
      ],
      "env": {
        "API_KEY": "…"
      }
    }
  }
}
```

### Cursor

Add to `.cursor/mcp.json` in your project, or `~/.cursor/mcp.json` for every project:

```json
{
  "mcpServers": {
    "optuna": {
      "command": "npx",
      "args": [
        "-y",
        "<package-from-readme>"
      ],
      "env": {
        "API_KEY": "…"
      }
    }
  }
}
```

### VS Code

Add to `.vscode/mcp.json`, then pick the server from Copilot's agent-mode tools menu:

```json
{
  "servers": {
    "optuna": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "<package-from-readme>"
      ]
    }
  }
}
```

### ChatGPT

ChatGPT connects to **remote servers only**, and this one runs on your machine. Either expose it through an MCP gateway that gives it a public URL, or use a client with native local support (Claude or Cursor).

## How we know

Verdict derived by matching the optuna organization against its GitHub presence and cross-checking against published MCP server lists.
