# lengthen_entity A write tool on the Pypi:best Cad MCP server. Agent View of the PolicyLayer registry record for `lengthen_entity`. HTML page: https://policylayer.com/tools/io-github-lokmenower-best-cad-mcp/lengthen-entity ## Facts - Tool: `lengthen_entity` - Server: Pypi:best Cad (`pypi:best-cad-mcp`) — https://policylayer.com/tools/io-github-lokmenower-best-cad-mcp.md - Install: `npx -y pypi:best-cad-mcp` - Homepage: https://github.com/LokmenoWer/best-cad-mcp - 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": "lengthen_entity", "arguments": {} } } ``` ## Why lengthen_entity is rated Medium Based on the name alone, 'lengthen_entity' likely modifies a CAD entity by changing its length, which is a reversible modification (Write). The sibling tools context (CAD automation server) supports this interpretation. However, with no description, confidence is low. Severity is medium as misuse could alter drawing geometry. From the tool's own definition: "Tool name 'lengthen_entity' — description is empty and uninformative." ## Use case AI agents use lengthen_entity to create or update resources in Pypi:best Cad, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Pypi:best Cad environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Pypi:best Cad: ```json { "version": "1", "default": "deny", "tools": { "lengthen_entity": { "limits": [ { "counter": "lengthen_entity_rate", "window": "minute", "max": 30, "scope": "grant" } ] } } } ``` ## Other tools on Pypi:best Cad (320) - `clear_spatial_annotations` — Destructive — https://policylayer.com/tools/io-github-lokmenower-best-cad-mcp/clear-spatial-annotations.md - `clear_understanding_cache` — Destructive — https://policylayer.com/tools/io-github-lokmenower-best-cad-mcp/clear-understanding-cache.md - `delete_entities` — Destructive — https://policylayer.com/tools/io-github-lokmenower-best-cad-mcp/delete-entities.md - `delete_entity` — Destructive — https://policylayer.com/tools/io-github-lokmenower-best-cad-mcp/delete-entity.md - `delete_layer` — Destructive — https://policylayer.com/tools/io-github-lokmenower-best-cad-mcp/delete-layer.md - `delete_named_view` — Destructive — https://policylayer.com/tools/io-github-lokmenower-best-cad-mcp/delete-named-view.md - `delete_selection_set` — Destructive — https://policylayer.com/tools/io-github-lokmenower-best-cad-mcp/delete-selection-set.md - `erase_selection_entities` — Destructive — https://policylayer.com/tools/io-github-lokmenower-best-cad-mcp/erase-selection-entities.md - `purge_drawing` — Destructive — https://policylayer.com/tools/io-github-lokmenower-best-cad-mcp/purge-drawing.md - `remove_hyperlink` — Destructive — https://policylayer.com/tools/io-github-lokmenower-best-cad-mcp/remove-hyperlink.md - `build_drawing_ir` — Execute — https://policylayer.com/tools/io-github-lokmenower-best-cad-mcp/build-drawing-ir.md - `check_runtime_environment` — Execute — https://policylayer.com/tools/io-github-lokmenower-best-cad-mcp/check-runtime-environment.md - `execute_cad_plan` — Execute — https://policylayer.com/tools/io-github-lokmenower-best-cad-mcp/execute-cad-plan.md - `execute_query` — Execute — https://policylayer.com/tools/io-github-lokmenower-best-cad-mcp/execute-query.md - `execute_sql_query` — Execute — https://policylayer.com/tools/io-github-lokmenower-best-cad-mcp/execute-sql-query.md - `highlight_entities` — Execute — https://policylayer.com/tools/io-github-lokmenower-best-cad-mcp/highlight-entities.md - `pan` — Execute — https://policylayer.com/tools/io-github-lokmenower-best-cad-mcp/pan.md - `plot_preview` — Execute — https://policylayer.com/tools/io-github-lokmenower-best-cad-mcp/plot-preview.md - `plot_to_device` — Execute — https://policylayer.com/tools/io-github-lokmenower-best-cad-mcp/plot-to-device.md - `regen` — Execute — https://policylayer.com/tools/io-github-lokmenower-best-cad-mcp/regen.md - `reload_xref` — Execute — https://policylayer.com/tools/io-github-lokmenower-best-cad-mcp/reload-xref.md - `render_drawing_view` — Execute — https://policylayer.com/tools/io-github-lokmenower-best-cad-mcp/render-drawing-view.md - `restart_mcp` — Execute — https://policylayer.com/tools/io-github-lokmenower-best-cad-mcp/restart-mcp.md - `restore_named_view` — Execute — https://policylayer.com/tools/io-github-lokmenower-best-cad-mcp/restore-named-view.md - `revolve_region` — Execute — https://policylayer.com/tools/io-github-lokmenower-best-cad-mcp/revolve-region.md - `select_on_screen` — Execute — https://policylayer.com/tools/io-github-lokmenower-best-cad-mcp/select-on-screen.md - `send_command` — Execute — https://policylayer.com/tools/io-github-lokmenower-best-cad-mcp/send-command.md - `set_active_layout` — Execute — https://policylayer.com/tools/io-github-lokmenower-best-cad-mcp/set-active-layout.md - `set_active_ucs` — Execute — https://policylayer.com/tools/io-github-lokmenower-best-cad-mcp/set-active-ucs.md - `set_variable` — Execute — https://policylayer.com/tools/io-github-lokmenower-best-cad-mcp/set-variable.md - …and 290 more: https://policylayer.com/tools/io-github-lokmenower-best-cad-mcp.md ## For agents This record is a snapshot.
