Installation & Authentication

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 necessary OAuth scopes 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. Set up Okto credentials:

Get these Okto credentials from https://dashboard.okto.tech/:

    OKTO_ENVIRONMENT=sandbox
OKTO_CLIENT_PRIVATE_KEY=your_private_key
OKTO_CLIENT_SWA=your_swa

3. Run Authentication:

You can authenticate in two ways:

a. Global Authentication (Recommended):

    # First time: Place gcp-oauth.keys.json in your home directory's .okto-mcp folder
mkdir -p ~/.okto-mcp
mv gcp-oauth.keys.json ~/.okto-mcp/

# Run authentication from anywhere
npx @okto_web3/okto-mcp-server@latest auth

b. Local Authentication:

    # Place gcp-oauth.keys.json in your current directory
# The file will be automatically copied to global config
npx @okto_web3/okto-mcp-server@latest auth

The authentication process will:

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

Note :

* After successful authentication, credentials are stored globally in `~/.okto-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

Claude Desktop Configuration

Add the following to your Claude Desktop configuration file (typically located at ~/Library/Application Support/Claude/claude_desktop_config.json on macOS):

{
  "mcpServers": {
    "okto": {
      "command": "node",
      "env": {
        "OKTO_ENVIRONMENT": "sandbox",
        "OKTO_CLIENT_PRIVATE_KEY": "your_private_key_here",
        "OKTO_CLIENT_SWA": "your_swa_here"
      },
      "args": [
        "/path/to/okto-mcp-server/build/index.js"
      ]
    }
  }
}

Replace:

• your_private_key_here with your Okto client private key
• your_swa_here with your Okto client SWA
• /path/to/okto-mcp-server with the actual path where you installed the server

Alternatively, if you installed via npm:

{
  "mcpServers": {
    "okto": {
      "command": "npx",
      "env": {
        "OKTO_ENVIRONMENT": "sandbox",
        "OKTO_CLIENT_PRIVATE_KEY": "your_private_key_here",
        "OKTO_CLIENT_SWA": "your_swa_here"
      },
      "args": [
        "@okto_web3/okto-mcp-server@latest"
      ]
    }
  }
}
