• src/servicenow_mcp/tools/project_tools.py:163-256 (handler)

  Main handler function that executes the create_project tool: validates params, prepares data, makes POST request to ServiceNow pm_project table, returns result.

• src/servicenow_mcp/utils/tool_utils.py:924-930 (registration)

  MCP tool registration entry in get_tool_definitions(): maps 'create_project' to handler (create_project_tool), schema (CreateProjectParams), description, and serialization.

  "create_project": (
      create_project_tool,
      CreateProjectParams,
      str,
      "Create a new project in ServiceNow",
