# get_material_quantities A read tool on the Revit MCP Server MCP server. Agent View of the PolicyLayer registry record for `get_material_quantities`. HTML page: https://policylayer.com/tools/demolinator-revit-mcp-server/get-material-quantities ## Facts - Tool: `get_material_quantities` - Server: Revit MCP Server (`demolinator/revit-mcp-server`) — https://policylayer.com/tools/demolinator-revit-mcp-server.md - Homepage: https://github.com/Demolinator/revit-mcp-server - Risk category: Read (Low risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Allowed ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "get_material_quantities", "arguments": {} } } ``` ## Why get_material_quantities is rated Low Based on naming convention and the analysis/documentation focus of the server, this tool retrieves material quantity data from a Revit model without creating, modifying, or deleting information. Empty description slightly reduces confidence but does not change categorization, as 'get_*' operations are conventionally read-only queries. From the tool's own definition: "Tool name 'get_material_quantities' indicates retrieval of quantitative data without modification. The description is empty, but the verb 'get' and the context of a 45-tool Revit MCP server focused on 'analysis' and 'documentation' suggest a read-only query…" ## Use case AI agents call get_material_quantities to retrieve information from Revit MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere. ## Recommended policy (PolicyLayer) Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Revit MCP Server: ```json { "version": "1", "default": "deny", "tools": { "get_material_quantities": {} } } ``` ## Other tools on Revit MCP Server (47) - `delete_elements` — Destructive — https://policylayer.com/tools/demolinator-revit-mcp-server/delete-elements.md - `execute_revit_code` — Execute — https://policylayer.com/tools/demolinator-revit-mcp-server/execute-revit-code.md - `set_active_view` — Execute — https://policylayer.com/tools/demolinator-revit-mcp-server/set-active-view.md - `transform_elements` — Execute — https://policylayer.com/tools/demolinator-revit-mcp-server/transform-elements.md - `ai_element_filter` — Read — https://policylayer.com/tools/demolinator-revit-mcp-server/ai-element-filter.md - `analyze_model_statistics` — Read — https://policylayer.com/tools/demolinator-revit-mcp-server/analyze-model-statistics.md - `check_clashes` — Read — https://policylayer.com/tools/demolinator-revit-mcp-server/check-clashes.md - `export_room_data` — Read — https://policylayer.com/tools/demolinator-revit-mcp-server/export-room-data.md - `get_current_view_elements` — Read — https://policylayer.com/tools/demolinator-revit-mcp-server/get-current-view-elements.md - `get_current_view_info` — Read — https://policylayer.com/tools/demolinator-revit-mcp-server/get-current-view-info.md - `get_element_properties` — Read — https://policylayer.com/tools/demolinator-revit-mcp-server/get-element-properties.md - `get_revit_model_info` — Read — https://policylayer.com/tools/demolinator-revit-mcp-server/get-revit-model-info.md - `get_revit_status` — Read — https://policylayer.com/tools/demolinator-revit-mcp-server/get-revit-status.md - `get_revit_view` — Read — https://policylayer.com/tools/demolinator-revit-mcp-server/get-revit-view.md - `get_selected_elements` — Read — https://policylayer.com/tools/demolinator-revit-mcp-server/get-selected-elements.md - `list_category_parameters` — Read — https://policylayer.com/tools/demolinator-revit-mcp-server/list-category-parameters.md - `list_families` — Read — https://policylayer.com/tools/demolinator-revit-mcp-server/list-families.md - `list_family_categories` — Read — https://policylayer.com/tools/demolinator-revit-mcp-server/list-family-categories.md - `list_levels` — Read — https://policylayer.com/tools/demolinator-revit-mcp-server/list-levels.md - `list_revit_views` — Read — https://policylayer.com/tools/demolinator-revit-mcp-server/list-revit-views.md - `clear_colors` — Write — https://policylayer.com/tools/demolinator-revit-mcp-server/clear-colors.md - `color_splash` — Write — https://policylayer.com/tools/demolinator-revit-mcp-server/color-splash.md - `create_detail_line` — Write — https://policylayer.com/tools/demolinator-revit-mcp-server/create-detail-line.md - `create_dimensions` — Write — https://policylayer.com/tools/demolinator-revit-mcp-server/create-dimensions.md - `create_duct` — Write — https://policylayer.com/tools/demolinator-revit-mcp-server/create-duct.md - `create_grid` — Write — https://policylayer.com/tools/demolinator-revit-mcp-server/create-grid.md - `create_level` — Write — https://policylayer.com/tools/demolinator-revit-mcp-server/create-level.md - `create_line_based_element` — Write — https://policylayer.com/tools/demolinator-revit-mcp-server/create-line-based-element.md - `create_mep_system` — Write — https://policylayer.com/tools/demolinator-revit-mcp-server/create-mep-system.md - `create_pipe` — Write — https://policylayer.com/tools/demolinator-revit-mcp-server/create-pipe.md - …and 17 more: https://policylayer.com/tools/demolinator-revit-mcp-server.md ## For agents This record is a snapshot.
