# graph_get_num_nodes Get number of nodes in the color graph for a timeline item. Agent View of the PolicyLayer registry record for `graph_get_num_nodes`. HTML page: https://policylayer.com/tools/samuelgursky-davinci-resolve-mcp/graph-get-num-nodes ## Facts - Tool: `graph_get_num_nodes` - 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: Read (Low risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Allowed ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "graph_get_num_nodes", "arguments": {} } } ``` ## Why graph_get_num_nodes is rated Low This tool performs a read-only operation—it queries and returns numeric information about an existing color graph. There are no side effects, no code execution, no data modification, and no destructive actions. The blast radius of misuse is minimal since the tool only retrieves information that already exists in the project. From the tool's own definition: "Tool name 'graph_get_num_nodes' and description 'Get number of nodes in the color graph for a timeline item' indicate a query operation that retrieves metadata about the color graph structure without modifying, executing, or deleting anything." ## Use case AI agents call graph_get_num_nodes to retrieve information from DaVinci Resolve MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere. ## Recommended policy (PolicyLayer) Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches DaVinci Resolve MCP: ```json { "version": "1", "default": "deny", "tools": { "graph_get_num_nodes": {} } } ``` ## 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.
