It serves as a bridge between Claude and ServiceNow, allowing for seamless integration. ## Features - Connect to ServiceNow instances using various authentication methods (Basic, OAuth, API Key) - Query ServiceNow records and tables - Create, update, and delete ServiceNow records - Execute ServiceNow scripts and workflows - Access and query the ServiceNow Service Catalog - Analyze and optimize the ServiceNow Service Catalog - Debug mode for troubleshooting - Support for both stdio and Server-Sent Events (SSE) communication ## Installation ### Prerequisites - Python 3.11 or higher - A ServiceNow instance with appropriate access credentials ### Setup 1. Clone this repository: ``` git clone https://github.com/yourusername/servicenow-mcp.git cd servicenow-mcp ``` 2. Create a virtual environment and install the package: ``` python -m venv .venv source .venv/bin/activate # On Windows: .venv\Scripts\activate pip install -e . ``` 3. Create a `.env` file with your ServiceNow credentials: ``` SERVICENOW_INSTANCE_URL=https://your-instance.service-now.com SERVICENOW_USERNAME=your-username SERVICENOW_PASSWORD=your-password SERVICENOW_AUTH_TYPE=basic # or oauth, api_key ``` ## Usage ### Standard (stdio) Mode To start the MCP server: ``` python -m servicenow_mcp.cli ``` Or with environment variables: ``` SERVICENOW_INSTANCE_URL=https://your-instance.service-now.com SERVICENOW_USERNAME=your-username SERVICENOW_PASSWORD=your-password SERVICENOW_AUTH_TYPE=basic python -m servicenow_mcp.cli ``` ### Server-Sent Events (SSE) Mode The ServiceNow MCP server can also run as a web server using Server-Sent Events (SSE) for communication, which allows for more flexible integration options. #### Starting the SSE Server You can start the SSE server using the provided CLI: ``` servicenow-mcp-sse --instance-url=https://your-instance.service-now.com --username=your-username --password=your-password ``` By default, the server will listen on `0.0.0.0:8080`. You can customize the host and port: ``` servicenow-mcp-sse --host=127.0.0.1 --port=8000 ``` #### Connecting to the SSE Server The SSE server exposes two main endpoints: - `/sse` - The SSE connection endpoint - `/messages/` - The endpoint for sending messages to the server #### Example See the `examples/sse_server_example.py` file for a complete example of setting up and running the SSE server. ```python from servicenow_mcp.server import ServiceNowMCP from servicenow_mcp.server_sse import create_starlette_app from servicenow_mcp.utils.config import ServerConfig, AuthConfig, AuthType, BasicAuthConfig import uvicorn # Create server configuration config = ServerConfig( instance_url="https://your-instance.service-now.com", auth=AuthConfig( type=AuthType.BASIC, config=BasicAuthConfig( username="your-username", password="your-password" ) ), debug=True, ) # Create ServiceNow MCP server servicenow_mcp = ServiceNowMCP(config) # Create Starlette app with SSE transport app = create_starlette_app(servicenow_mcp, debug=True) # Start the web server uvicorn.run(app, host="0.0.0.0", port=8080) ``` ## Tool Packaging (Optional) To manage the number of tools exposed to the language model (especially in environments with limits), the ServiceNow MCP server supports loading subsets of tools called "packages". This is controlled via the `MCP_TOOL_PACKAGE` environment variable. ### Configuration 1. **Environment Variable:** Set the `MCP_TOOL_PACKAGE` environment variable to the name of the desired package. ```bash export MCP_TOOL_PACKAGE=catalog_builder ``` 2. **Package Definitions:** The available packages and the tools they include are defined in `config/tool_packages.yaml`. You can customize this file to create your own packages. ### Behavior - If `MCP_TOOL_PACKAGE` is set to a valid package name defined in `config/tool_packages.yaml`, only the tools listed in that package will be loaded. - If `MCP_TOOL_PACKAGE` is **not set** or is empty, the `full` package (containing all tools) is loaded by default. - If `MCP_TOOL_PACKAGE` is set to an invalid package name, the `none` package is loaded (no tools except `list_tool_packages`), and a warning is logged. - Setting `MCP_TOOL_PACKAGE=none` explicitly loads no tools (except `list_tool_packages`). ### Available Packages (Default) The default `config/tool_packages.yaml` includes the following role-based packages: - `service_desk`: Tools for incident handling and basic user/knowledge lookup. - `catalog_builder`: Tools for creating and managing service catalog items, categories, variables, and related scripting (UI Policies, User Criteria). - `change_coordinator`: Tools for managing the change request lifecycle, including tasks and approvals. - `knowledge_author`: Tools for creating and managing knowledge bases, categories, and articles. - `platform_developer`: Tools for server-side scripting (Script Includes), workflow development, and deployment (Changesets). - `system_administrator`: Tools for user/group management and viewing system logs. - `agile_management`: Tools for managing user stories, epics, scrum tasks, and projects. - `full`: Includes all available tools (default). - `none`: Includes no tools (except `list_tool_packages`). ### Introspection Tool - **`list_tool_packages`**: Lists all available tool package names defined in the configuration and shows the currently loaded package. This tool is available in all packages except `none`. ## Available Tools **Note:** The availability of the following tools depends on the loaded tool package (see Tool Packaging section above). By default (`full` package), all tools are available. #### Incident Management Tools 1. **create_incident** - Create a new incident in ServiceNow 2. **update_incident** - Update an existing incident in ServiceNow 3. **add_comment** -

This error occurs when you pass a `CreateChangeRequestParams` object instead of a dictionary to the `create_change_request` function. - Solution: Make sure you're passing a dictionary with the parameters, not a Pydantic model object. - Note: The change management tools have been updated to handle this error automatically. The functions will now attempt to unwrap parameters if they're incorrectly wrapped or passed as a Pydantic model object. 2. **Error: `Missing required parameter 'type'`** - This error occurs when you don't provide all required parameters for creating a change request. - Solution: Make sure to include all required parameters. For `create_change_request`, both `short_description` and `type` are required. 3. **Error: `Invalid value for parameter 'type'`** - This error occurs when you provide an invalid value for the `type` parameter. - Solution: Use one of the valid values: "normal", "standard", or "emergency". 4. **Error: `Cannot find get_headers method in either auth_manager or server_config`** - This error occurs when the parameters are passed in the wrong order or when using objects that don't have the required methods. - Solution: Make sure you're passing the `auth_manager` and `server_config` parameters in the correct order. The functions have been updated to handle parameter swapping automatically. ### Contributing Contributions are welcome! Please feel free to submit a Pull Request. 1. Fork the repository 2.
