## Setup

## Setup

**Installing via Smithery:**

```bash
npx -y @smithery/cli install @gongrzhe/server-gmail-autoauth-mcp --client claude
```

**Installing Manually:**

1.  Create a Google Cloud Project and obtain credentials:

    a. Create a Google Cloud Project:
       - Go to [Google Cloud Console](https://console.cloud.google.com/)
       - Create a new project or select an existing one
       - Enable the Gmail API for your project

    b. Create OAuth 2.0 Credentials:
       - Go to "APIs & Services" > "Credentials"
       - Click "Create Credentials" > "OAuth client ID"
       - Choose either "Desktop app" or "Web application" as application type
       - Give it a name and click "Create"
       - For Web application, add `http://localhost:3000/oauth2callback` to the authorized redirect URIs
       - Download the JSON file of your client's OAuth keys
       - Rename the key file to `gcp-oauth.keys.json`

2.  Run Authentication:

    You can authenticate in two ways:

    a. Global Authentication (Recommended):
    ```bash
    # First time: Place gcp-oauth.keys.json in your home directory's .gmail-mcp folder
    mkdir -p ~/.gmail-mcp
    mv gcp-oauth.keys.json ~/.gmail-mcp/

    # Run authentication from anywhere
    npx @gongrzhe/server-gmail-autoauth-mcp auth
    ```

    b. Local Authentication:
    ```bash
    # Place gcp-oauth.keys.json in your current directory
    # The file will be automatically copied to global config
    npx @gongrzhe/server-gmail-autoauth-mcp auth
    ```

    The authentication process will:
    - Look for `gcp-oauth.keys.json` in the current directory or `~/.gmail-mcp/`
    - If found in current directory, copy it to `~/.gmail-mcp/`
    - Open your default browser for Google authentication
    - Save credentials as `~/.gmail-mcp/credentials.json`

    > **Note**:
    > - After successful authentication, credentials are stored globally in `~/.gmail-mcp/` and can be used from any directory
    > - Both Desktop app and Web application credentials are supported
    > - For Web application credentials, make sure to add `http://localhost:3000/oauth2callback` to your authorized redirect URIs

3.  Configure in Claude Desktop:

```json
{
  "mcpServers": {
    "gmail": {
      "command": "npx",
      "args": [
        "@gongrzhe/server-gmail-autoauth-mcp"
      ]
    }
  }
}
```

**Docker Support:**

1. Authentication:
```bash
docker run -i --rm \
  --mount type=bind,source=/path/to/gcp-oauth.keys.json,target=/gcp-oauth.keys.json \
  -v mcp-gmail:/gmail-server \
  -e GMAIL_OAUTH_PATH=/gcp-oauth.keys.json \
  -e "GMAIL_CREDENTIALS_PATH=/gmail-server/credentials.json" \
  -p 3000:3000 \
  mcp/gmail auth
```

2. Usage:
```json
{
  "mcpServers": {
    "gmail": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "-v",
        "mcp-gmail:/gmail-server",
        "-e",
        "GMAIL_CREDENTIALS_PATH=/gmail-server/credentials.json",
        "mcp/gmail"
      ]
    }
  }
}
```
