    Before you begin

    Before connecting Claude Desktop to the Service Mapping MCP Server, confirm the following requirements are met.

    • Claude Desktop is installed on your computer.
    • You have a Claude account with permission to add custom MCP connectors. If your organization manages Claude through an Enterprise or Team plan, verify that custom connectors are enabled in your organization's settings.
    • The Service Mapping MCP Server is active, and you have the following details:
      • MCP Server URL
      • OAuth Client ID
      • OAuth Client Secret
      For more information, see: Activate the Now Assist CMDB MCP Server for Service Mapping tools
    • Verify that you have the required role configuration. For more information, see Configure roles for the Service Mapping MCP tools.

      Role required: service_mapping_user assigned with the sn_sm_gen_ai.sm_mcp_user role

      Figure 1. The role containment chain
      service_mapping_user contains sn_sm_gen_ai.sm_mcp_user, which contains sn_mcp_server.viewer. The sn_sm_gen_ai.sm_mcp_admin role separately contains sn_sm_gen_ai.sm_mcp_user.

    About this task

    Claude Desktop supports custom MCP connectors that let Claude query external data sources on your behalf. After you add the Service Mapping MCP Server as a connector and authorize it with your ServiceNow credentials, Claude can call the Service Mapping MCP tools whenever you ask a question about application services in a chat.
