# check_runtime_environment Run runtime preflight checks before live CAD work. Agent View of the PolicyLayer registry record for `check_runtime_environment`. HTML page: https://policylayer.com/tools/io-github-lokmenower-best-cad-mcp/check-runtime-environment ## Facts - Tool: `check_runtime_environment` - 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: Execute (High 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": "check_runtime_environment", "arguments": {} } } ``` ## Why check_runtime_environment is rated High The tool executes preflight checks against the runtime CAD environment. While it appears read-only in intent, 'Run' indicates active execution of operations against a live system. It doesn't create/modify data but triggers external operations (probing the CAD runtime). Severity is medium because misuse could interfere with CAD session state or expose environment configuration details. From the tool's own definition: "'Run runtime preflight checks' — actively runs/executes checks against the live environment" ## Use case AI agents invoke check_runtime_environment to trigger actions in Pypi:best Cad. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started. ## 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": { "check_runtime_environment": { "limits": [ { "counter": "check_runtime_environment_rate", "window": "minute", "max": 10, "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 - `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 - `zoom_all` — Execute — https://policylayer.com/tools/io-github-lokmenower-best-cad-mcp/zoom-all.md - …and 290 more: https://policylayer.com/tools/io-github-lokmenower-best-cad-mcp.md ## For agents This record is a snapshot.
