# create_pipe A write tool on the Revit MCP Server MCP server. Agent View of the PolicyLayer registry record for `create_pipe`. HTML page: https://policylayer.com/tools/demolinator-revit-mcp-server/create-pipe ## Facts - Tool: `create_pipe` - 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: Write (Medium risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Rate-limited ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "create_pipe", "arguments": {} } } ``` ## Why create_pipe is rated Medium Creating pipes in a Revit model modifies the architectural/MEP design document by adding new geometry and elements. This is reversible (pipes can be deleted), so it falls under Write rather than Destructive. While the description is empty, the tool name combined with the server's MEP focus and sibling tool patterns strongly indicate data creation. From the tool's own definition: "Tool name 'create_pipe' indicates creation of MEP (mechanical, electrical, plumbing) piping elements in Revit." ## Use case AI agents use create_pipe to create or update resources in Revit MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Revit MCP Server environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Revit MCP Server: ```json { "version": "1", "default": "deny", "tools": { "create_pipe": { "limits": [ { "counter": "create_pipe_rate", "window": "minute", "max": 30, "scope": "grant" } ] } } } ``` ## 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_material_quantities` — Read — https://policylayer.com/tools/demolinator-revit-mcp-server/get-material-quantities.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 - …and 17 more: https://policylayer.com/tools/demolinator-revit-mcp-server.md ## For agents This record is a snapshot.
