# set_xdata A write tool on the Pypi:best Cad MCP server. Agent View of the PolicyLayer registry record for `set_xdata`. HTML page: https://policylayer.com/tools/io-github-lokmenower-best-cad-mcp/set-xdata ## Facts - Tool: `set_xdata` - 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": "set_xdata", "arguments": {} } } ``` ## Why set_xdata is rated Medium Extended data in AutoCAD is custom metadata attached to drawing objects. Setting xdata modifies but does not delete or irreversibly destroy data, and does not execute arbitrary code or trigger external operations. This is reversible (can be overwritten or removed), placing it in Write rather than Destructive or Execute. From the tool's own definition: "Tool name 'set_xdata' indicates setting extended data (xdata) on AutoCAD objects. This is a write operation that modifies object metadata/properties in a CAD drawing." ## Use case AI agents use set_xdata 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": { "set_xdata": { "limits": [ { "counter": "set_xdata_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.
