# save_asset Force save a specific asset. Agent View of the PolicyLayer registry record for `save_asset`. HTML page: https://policylayer.com/tools/jjpxdev-unreal-mcp/save-asset ## Facts - Tool: `save_asset` - Server: Unreal (`@jjpxdev/unreal-mcp`) — https://policylayer.com/tools/jjpxdev-unreal-mcp.md - Install: `npx -y @jjpxdev/unreal-mcp` - Homepage: https://www.npmjs.com/package/@jjpxdev/unreal-mcp - Risk category: Write (Medium risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 1 (1 required) - Recommended policy verdict: Rate-limited ## Parameters | Parameter | Type | Required | Description | | --- | --- | --- | --- | | `asset_path` | string | yes | Asset path to save | Parameters from the server's own tool schema. ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "save_asset", "arguments": { "asset_path": "" } } } ``` ## Why save_asset is rated Medium The tool modifies and persists asset state within Unreal Engine's project files. While save operations are reversible (existing saved versions can be restored or changes undone), they alter the project state and commit changes to disk. This is a Write action rather than Destructive since the asset itself is not deleted or irreversibly corrupted, and backups/version control may exist. From the tool's own definition: "Tool name 'save_asset' and description 'Force save a specific asset' indicate the tool persists data modifications to asset files." ## Use case AI agents use save_asset to create or update resources in Unreal, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Unreal environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Unreal: ```json { "version": "1", "default": "deny", "tools": { "save_asset": { "limits": [ { "counter": "save_asset_rate", "window": "minute", "max": 30, "scope": "grant" } ] } } } ``` ## Other tools on Unreal (126) - `delete_actor` — Destructive — https://policylayer.com/tools/jjpxdev-unreal-mcp/delete-actor.md - `delete_asset` — Destructive — https://policylayer.com/tools/jjpxdev-unreal-mcp/delete-asset.md - `delete_material_expression` — Destructive — https://policylayer.com/tools/jjpxdev-unreal-mcp/delete-material-expression.md - `remove_graph_node` — Destructive — https://policylayer.com/tools/jjpxdev-unreal-mcp/remove-graph-node.md - `build_cook_run` — Execute — https://policylayer.com/tools/jjpxdev-unreal-mcp/build-cook-run.md - `build_graph` — Execute — https://policylayer.com/tools/jjpxdev-unreal-mcp/build-graph.md - `build_plugin` — Execute — https://policylayer.com/tools/jjpxdev-unreal-mcp/build-plugin.md - `build_target` — Execute — https://policylayer.com/tools/jjpxdev-unreal-mcp/build-target.md - `call_preset_function` — Execute — https://policylayer.com/tools/jjpxdev-unreal-mcp/call-preset-function.md - `clean_project` — Execute — https://policylayer.com/tools/jjpxdev-unreal-mcp/clean-project.md - `compile_blueprint` — Execute — https://policylayer.com/tools/jjpxdev-unreal-mcp/compile-blueprint.md - `content_audit` — Execute — https://policylayer.com/tools/jjpxdev-unreal-mcp/content-audit.md - `cook_content` — Execute — https://policylayer.com/tools/jjpxdev-unreal-mcp/cook-content.md - `execute_console_command` — Execute — https://policylayer.com/tools/jjpxdev-unreal-mcp/execute-console-command.md - `execute_python` — Execute — https://policylayer.com/tools/jjpxdev-unreal-mcp/execute-python.md - `generate_lods` — Execute — https://policylayer.com/tools/jjpxdev-unreal-mcp/generate-lods.md - `package_project` — Execute — https://policylayer.com/tools/jjpxdev-unreal-mcp/package-project.md - `recompile_material` — Execute — https://policylayer.com/tools/jjpxdev-unreal-mcp/recompile-material.md - `reinit_niagara_system` — Execute — https://policylayer.com/tools/jjpxdev-unreal-mcp/reinit-niagara-system.md - `render_sequence` — Execute — https://policylayer.com/tools/jjpxdev-unreal-mcp/render-sequence.md - `reset_niagara_system` — Execute — https://policylayer.com/tools/jjpxdev-unreal-mcp/reset-niagara-system.md - `run_all_automation_tests` — Execute — https://policylayer.com/tools/jjpxdev-unreal-mcp/run-all-automation-tests.md - `run_automation_test` — Execute — https://policylayer.com/tools/jjpxdev-unreal-mcp/run-automation-test.md - `run_automation_tests_by_category` — Execute — https://policylayer.com/tools/jjpxdev-unreal-mcp/run-automation-tests-by-category.md - `run_editor_utility_blueprint` — Execute — https://policylayer.com/tools/jjpxdev-unreal-mcp/run-editor-utility-blueprint.md - `run_editor_utility_widget` — Execute — https://policylayer.com/tools/jjpxdev-unreal-mcp/run-editor-utility-widget.md - `run_gauntlet` — Execute — https://policylayer.com/tools/jjpxdev-unreal-mcp/run-gauntlet.md - `run_map_check` — Execute — https://policylayer.com/tools/jjpxdev-unreal-mcp/run-map-check.md - `run_stat_command` — Execute — https://policylayer.com/tools/jjpxdev-unreal-mcp/run-stat-command.md - `spawn_niagara_at_location` — Execute — https://policylayer.com/tools/jjpxdev-unreal-mcp/spawn-niagara-at-location.md - …and 96 more: https://policylayer.com/tools/jjpxdev-unreal-mcp.md ## For agents This record is a snapshot.
