# ti_delete_marker_by_custom_data Delete a marker by custom data on a timeline item. Agent View of the PolicyLayer registry record for `ti_delete_marker_by_custom_data`. HTML page: https://policylayer.com/tools/samuelgursky-davinci-resolve-mcp/ti-delete-marker-by-custom-data ## Facts - Tool: `ti_delete_marker_by_custom_data` - Server: DaVinci Resolve MCP (`samuelgursky/davinci-resolve-mcp`) — https://policylayer.com/tools/samuelgursky-davinci-resolve-mcp.md - Homepage: https://github.com/samuelgursky/davinci-resolve-mcp - Risk category: Destructive (Critical risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Hidden ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "ti_delete_marker_by_custom_data", "arguments": {} } } ``` ## Why ti_delete_marker_by_custom_data is rated Critical This tool performs an irreversible deletion operation on timeline metadata (markers). While markers are not the primary video content, they represent important editorial metadata that documents decisions, cues, or annotations made during editing. Deletion cannot be reversed by the tool, and an AI agent could maliciously or accidentally remove markers that are critical to the project workflow. From the tool's own definition: "Tool name contains 'delete' and description states 'Delete a marker by custom data on a timeline item.' The action is irreversible—deleting a marker from a video timeline cannot be undone programmatically by the tool itself." ## Use case AI agents call ti_delete_marker_by_custom_data to permanently remove resources in DaVinci Resolve MCP, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo. ## Recommended policy (PolicyLayer) Verdict: **Hidden**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches DaVinci Resolve MCP: ```json { "version": "1", "default": "deny", "hide": [ "ti_delete_marker_by_custom_data" ] } ``` ## Other tools on DaVinci Resolve MCP (354) - `archive_project` — Destructive — https://policylayer.com/tools/samuelgursky-davinci-resolve-mcp/archive-project.md - `clear_clip_flags` — Destructive — https://policylayer.com/tools/samuelgursky-davinci-resolve-mcp/clear-clip-flags.md - `clear_clip_transcription` — Destructive — https://policylayer.com/tools/samuelgursky-davinci-resolve-mcp/clear-clip-transcription.md - `clear_folder_transcription` — Destructive — https://policylayer.com/tools/samuelgursky-davinci-resolve-mcp/clear-folder-transcription.md - `clear_transcription` — Destructive — https://policylayer.com/tools/samuelgursky-davinci-resolve-mcp/clear-transcription.md - `close_project` — Destructive — https://policylayer.com/tools/samuelgursky-davinci-resolve-mcp/close-project.md - `delete_burn_in_preset` — Destructive — https://policylayer.com/tools/samuelgursky-davinci-resolve-mcp/delete-burn-in-preset.md - `delete_clip_marker_at_frame` — Destructive — https://policylayer.com/tools/samuelgursky-davinci-resolve-mcp/delete-clip-marker-at-frame.md - `delete_clip_marker_by_custom_data` — Destructive — https://policylayer.com/tools/samuelgursky-davinci-resolve-mcp/delete-clip-marker-by-custom-data.md - `delete_clip_markers_by_color` — Destructive — https://policylayer.com/tools/samuelgursky-davinci-resolve-mcp/delete-clip-markers-by-color.md - `delete_clip_mattes` — Destructive — https://policylayer.com/tools/samuelgursky-davinci-resolve-mcp/delete-clip-mattes.md - `delete_color_group` — Destructive — https://policylayer.com/tools/samuelgursky-davinci-resolve-mcp/delete-color-group.md - `delete_keyframe` — Destructive — https://policylayer.com/tools/samuelgursky-davinci-resolve-mcp/delete-keyframe.md - `delete_layout_preset_tool` — Destructive — https://policylayer.com/tools/samuelgursky-davinci-resolve-mcp/delete-layout-preset-tool.md - `delete_media_pool_clips` — Destructive — https://policylayer.com/tools/samuelgursky-davinci-resolve-mcp/delete-media-pool-clips.md - `delete_media_pool_folders` — Destructive — https://policylayer.com/tools/samuelgursky-davinci-resolve-mcp/delete-media-pool-folders.md - `delete_project` — Destructive — https://policylayer.com/tools/samuelgursky-davinci-resolve-mcp/delete-project.md - `delete_project_folder` — Destructive — https://policylayer.com/tools/samuelgursky-davinci-resolve-mcp/delete-project-folder.md - `delete_render_job` — Destructive — https://policylayer.com/tools/samuelgursky-davinci-resolve-mcp/delete-render-job.md - `delete_render_preset` — Destructive — https://policylayer.com/tools/samuelgursky-davinci-resolve-mcp/delete-render-preset.md - `delete_stills_from_album` — Destructive — https://policylayer.com/tools/samuelgursky-davinci-resolve-mcp/delete-stills-from-album.md - `delete_timelines_by_id` — Destructive — https://policylayer.com/tools/samuelgursky-davinci-resolve-mcp/delete-timelines-by-id.md - `delete_user_preferences_preset` — Destructive — https://policylayer.com/tools/samuelgursky-davinci-resolve-mcp/delete-user-preferences-preset.md - `folder_clear_transcription` — Destructive — https://policylayer.com/tools/samuelgursky-davinci-resolve-mcp/folder-clear-transcription.md - `folder_remove_motion_blur` — Destructive — https://policylayer.com/tools/samuelgursky-davinci-resolve-mcp/folder-remove-motion-blur.md - `graph_reset_all_grades` — Destructive — https://policylayer.com/tools/samuelgursky-davinci-resolve-mcp/graph-reset-all-grades.md - `quit_resolve` — Destructive — https://policylayer.com/tools/samuelgursky-davinci-resolve-mcp/quit-resolve.md - `ti_clear_flags` — Destructive — https://policylayer.com/tools/samuelgursky-davinci-resolve-mcp/ti-clear-flags.md - `ti_delete_fusion_comp` — Destructive — https://policylayer.com/tools/samuelgursky-davinci-resolve-mcp/ti-delete-fusion-comp.md - `ti_delete_marker_at_frame` — Destructive — https://policylayer.com/tools/samuelgursky-davinci-resolve-mcp/ti-delete-marker-at-frame.md - …and 324 more: https://policylayer.com/tools/samuelgursky-davinci-resolve-mcp.md ## For agents This record is a snapshot.
