📋 Prerequisites

  • Python 3.8+
  • ServiceNow Instance (Developer, Enterprise, or higher)
  • API Access - REST API enabled with appropriate permissions
  • OAuth 2.0 Credentials: CLIENT_ID and CLIENT_SECRET (contact maintainer)

🚀 Quick Start

1. Installation

git clone https://github.com/Papamzor/personal-mcp-servicenow.git
cd personal-mcp-servicenow

# Create virtual environment
python -m venv venv
source venv/bin/activate  # On Windows: venv\\Scripts\\activate

# Install dependencies
pip install -r requirements.txt
python -m spacy download en_core_web_sm

2. Configuration

Create .env file in project root:

# OAuth 2.0 Authentication (Required)
SERVICENOW_INSTANCE=https://your-instance.service-now.com
SERVICENOW_CLIENT_ID=your_oauth_client_id
SERVICENOW_CLIENT_SECRET=your_oauth_client_secret

⚠️ OAuth 2.0 Credentials Required: This application exclusively uses OAuth 2.0 authentication for security. Contact the project maintainer to obtain OAuth client credentials for your ServiceNow instance.

3. OAuth 2.0 Setup

See for complete ServiceNow OAuth configuration, or contact the maintainer for pre-configured credentials.

4. Verification

# Test environment setup (local test - no ServiceNow connection needed), expected result 2/3 pass (.env file should not be readable)
python -m Testing.test_oauth_simple

# Test actual ServiceNow connectivity by running some CMDB tools (requires valid .env configuration)
python -m Testing.test_cmdb_tools

# Test OAuth with your ServiceNow instance (requires OAuth setup), should return token validity details
python -c "import asyncio; from utility_tools import now_test_oauth; print(asyncio.run(now_test_oauth()))"

Verification Steps Explained:

  • Step 1: Tests OAuth client creation and environment variables (offline test)
  • Step 2: Tests actual ServiceNow API connectivity and CMDB functionality
  • Step 3: Tests OAuth authentication flow with your ServiceNow instance

5. Claude Desktop Integration

To use this MCP server with Claude Desktop, add the following configuration to your Claude Desktop settings:

Location of config file:

  • Windows: %APPDATA%\Claude\claude_desktop_config.json
  • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

Add this configuration:

{
  "mcpServers": {
    "servicenow": {
      "command": "python",
      "args": ["/full/path/to/personal-mcp-servicenow/tools.py"],
      "env": {
        "SERVICENOW_INSTANCE": "https://your-instance.service-now.com",
        "SERVICENOW_CLIENT_ID": "your_oauth_client_id",
        "SERVICENOW_CLIENT_SECRET": "your_oauth_client_secret"
      }
    }
  }
}

Important Notes:

  • Replace /full/path/to/personal-mcp-servicenow/ with your actual installation path
  • Replace the environment variables with your actual ServiceNow credentials
  • Restart Claude Desktop after adding this configuration
  • The server will auto-start when Claude Desktop launches

Alternative: Using .env file (Recommended) If you prefer to keep credentials in your .env file:

{
  "mcpServers": {
    "servicenow": {
      "command": "python",
      "args": ["/full/path/to/personal-mcp-servicenow/tools.py"]
    }
  }
}

6. Standalone Server (Optional)

To run the MCP server independently:
