## Installation

Requires [Node.js](https://nodejs.org/) 18+ and a [MinerU API key](https://mineru.net).

### CLI Install (one-liner)

```bash
# Claude Code
claude mcp add mineru-mcp -e MINERU_API_KEY=your-api-key -- npx -y mineru-mcp

# Codex CLI (OpenAI)
codex mcp add mineru --env MINERU_API_KEY=your-api-key -- npx -y mineru-mcp

# Gemini CLI (Google)
gemini mcp add -e MINERU_API_KEY=your-api-key mineru npx -y mineru-mcp
```

### Claude Desktop

Add to your `claude_desktop_config.json`:

| OS | Config path |
|----|-------------|
| macOS | `~/Library/Application Support/Claude/claude_desktop_config.json` |
| Windows | `%APPDATA%\Claude\claude_desktop_config.json` |
| Linux | `~/.config/Claude/claude_desktop_config.json` |

```json
{
  "mcpServers": {
    "mineru": {
      "command": "npx",
      "args": ["-y", "mineru-mcp"],
      "env": {
        "MINERU_API_KEY": "your-api-key"
      }
    }
  }
}
```

### VS Code

Add to `.vscode/mcp.json` (workspace) or open Command Palette > `MCP: Open User Configuration` (global):

```json
{
  "servers": {
    "mineru": {
      "command": "npx",
      "args": ["-y", "mineru-mcp"],
      "env": {
        "MINERU_API_KEY": "your-api-key"
      }
    }
  }
}
```

> **Note**: VS Code uses `"servers"` as the top-level key, not `"mcpServers"`. Other VS Code forks (Trae, Void, PearAI, etc.) typically use this same format.

### Cursor

Add to `~/.cursor/mcp.json` (global) or `.cursor/mcp.json` (project):

```json
{
  "mcpServers": {
    "mineru": {
      "command": "npx",
      "args": ["-y", "mineru-mcp"],
      "env": {
        "MINERU_API_KEY": "your-api-key"
      }
    }
  }
}
```

### Windsurf

Add to `~/.codeium/windsurf/mcp_config.json` (Windows: `%USERPROFILE%\.codeium\windsurf\mcp_config.json`):

```json
{
  "mcpServers": {
    "mineru": {
      "command": "npx",
      "args": ["-y", "mineru-mcp"],
      "env": {
        "MINERU_API_KEY": "your-api-key"
      }
    }
  }
}
```

### Cline

Open MCP Servers icon in Cline panel > Configure > Advanced MCP Settings, then add:

```json
{
  "mcpServers": {
    "mineru": {
      "command": "npx",
      "args": ["-y", "mineru-mcp"],
      "env": {
        "MINERU_API_KEY": "your-api-key"
      }
    }
  }
}
```

### Cherry Studio

In Settings > MCP Servers > Add Server, set Type to `STDIO`, Command to `npx`, Args to `-y mineru-mcp`, and add environment variable `MINERU_API_KEY`. Or paste in JSON/Code mode:

```json
{
  "mineru": {
    "name": "MinerU",
    "command": "npx",
    "args": ["-y", "mineru-mcp"],
    "env": {
      "MINERU_API_KEY": "your-api-key"
    },
    "isActive": true
  }
}
```

### Witsy

In Settings > MCP Servers, add a new server with Type: `stdio`, Command: `npx`, Args: `-y mineru-mcp`, and set environment variable `MINERU_API_KEY` to your API key.

### Codex CLI (TOML config)

Alternatively, edit `~/.codex/config.toml` directly:

```toml
[mcp_servers.mineru]
command = "npx"
args = ["-y", "mineru-mcp"]

[mcp_servers.mineru.env]
MINERU_API_KEY = "your-api-key"
```

### Gemini CLI (JSON config)

Alternatively, edit `~/.gemini/settings.json` directly:

```json
{
  "mcpServers": {
    "mineru": {
      "command": "npx",
      "args": ["-y", "mineru-mcp"],
      "env": {
        "MINERU_API_KEY": "your-api-key"
      }
    }
  }
}
```

### Windows

On Windows, `npx` requires a shell wrapper. Replace `"command": "npx"` with:

```json
{
  "command": "cmd",
  "args": ["/c", "npx", "-y", "mineru-mcp"],
  "env": {
    "MINERU_API_KEY": "your-api-key"
  }
}
```

For CLI tools on Windows:

```bash
claude mcp add mineru-mcp -e MINERU_API_KEY=your-api-key -- cmd /c npx -y mineru-mcp
codex mcp add mineru --env MINERU_API_KEY=your-api-key -- cmd /c npx -y mineru-mcp
```

### ChatGPT

ChatGPT only supports remote MCP servers over HTTPS — local stdio servers like this one are not directly supported. You would need to deploy behind a public URL with HTTP transport.
