# list_custom_nodes List your own custom nodes. Supports search and category filtering. Agent View of the PolicyLayer registry record for `list_custom_nodes`. HTML page: https://policylayer.com/tools/flowdot-llc-mcp-server/list-custom-nodes ## Facts - Tool: `list_custom_nodes` - Server: FlowDot MCP Server (`flowdot-llc/mcp-server`) — https://policylayer.com/tools/flowdot-llc-mcp-server.md - Homepage: https://github.com/flowdot-llc/mcp-server - 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": "list_custom_nodes", "arguments": {} } } ``` ## Why list_custom_nodes is rated Low This tool retrieves existing custom node data without any side effects. It performs data querying with optional filtering, which is characteristic of Read operations. The limited scope to 'your own' custom nodes and absence of any write, execute, or delete capabilities keeps severity low. From the tool's own definition: "Tool name 'list_custom_nodes' and description states it 'List[s] your own custom nodes' with 'search and category filtering' — purely a query/retrieval operation with no modification or execution capability." ## Use case AI agents call list_custom_nodes to retrieve information from FlowDot MCP Server 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 FlowDot MCP Server: ```json { "version": "1", "default": "deny", "tools": { "list_custom_nodes": {} } } ``` ## Other tools on FlowDot MCP Server (206) - `browser_act` — Destructive — https://policylayer.com/tools/flowdot-llc-mcp-server/browser-act.md - `cancel_execution` — Destructive — https://policylayer.com/tools/flowdot-llc-mcp-server/cancel-execution.md - `delete_agent_character` — Destructive — https://policylayer.com/tools/flowdot-llc-mcp-server/delete-agent-character.md - `delete_app` — Destructive — https://policylayer.com/tools/flowdot-llc-mcp-server/delete-app.md - `delete_app_file` — Destructive — https://policylayer.com/tools/flowdot-llc-mcp-server/delete-app-file.md - `delete_connection` — Destructive — https://policylayer.com/tools/flowdot-llc-mcp-server/delete-connection.md - `delete_custom_node` — Destructive — https://policylayer.com/tools/flowdot-llc-mcp-server/delete-custom-node.md - `delete_goal` — Destructive — https://policylayer.com/tools/flowdot-llc-mcp-server/delete-goal.md - `delete_goal_milestone` — Destructive — https://policylayer.com/tools/flowdot-llc-mcp-server/delete-goal-milestone.md - `delete_goal_task` — Destructive — https://policylayer.com/tools/flowdot-llc-mcp-server/delete-goal-task.md - `delete_image` — Destructive — https://policylayer.com/tools/flowdot-llc-mcp-server/delete-image.md - `delete_input_preset` — Destructive — https://policylayer.com/tools/flowdot-llc-mcp-server/delete-input-preset.md - `delete_knowledge_category` — Destructive — https://policylayer.com/tools/flowdot-llc-mcp-server/delete-knowledge-category.md - `delete_knowledge_document` — Destructive — https://policylayer.com/tools/flowdot-llc-mcp-server/delete-knowledge-document.md - `delete_node` — Destructive — https://policylayer.com/tools/flowdot-llc-mcp-server/delete-node.md - `delete_recipe` — Destructive — https://policylayer.com/tools/flowdot-llc-mcp-server/delete-recipe.md - `delete_recipe_step` — Destructive — https://policylayer.com/tools/flowdot-llc-mcp-server/delete-recipe-step.md - `delete_recipe_store` — Destructive — https://policylayer.com/tools/flowdot-llc-mcp-server/delete-recipe-store.md - `delete_workflow` — Destructive — https://policylayer.com/tools/flowdot-llc-mcp-server/delete-workflow.md - `email_delete` — Destructive — https://policylayer.com/tools/flowdot-llc-mcp-server/email-delete.md - `mcp__flowdot__delete_agent_toolkit` — Destructive — https://policylayer.com/tools/flowdot-llc-mcp-server/mcp--flowdot--delete-agent-toolkit.md - `mcp__flowdot__delete_toolkit_tool` — Destructive — https://policylayer.com/tools/flowdot-llc-mcp-server/mcp--flowdot--delete-toolkit-tool.md - `mcp__flowdot__uninstall_toolkit` — Destructive — https://policylayer.com/tools/flowdot-llc-mcp-server/mcp--flowdot--uninstall-toolkit.md - `panic_clear` — Destructive — https://policylayer.com/tools/flowdot-llc-mcp-server/panic-clear.md - `revoke_kb_access` — Destructive — https://policylayer.com/tools/flowdot-llc-mcp-server/revoke-kb-access.md - `unlink_property_kb_source` — Destructive — https://policylayer.com/tools/flowdot-llc-mcp-server/unlink-property-kb-source.md - `browser_launch` — Execute — https://policylayer.com/tools/flowdot-llc-mcp-server/browser-launch.md - `browser_navigate` — Execute — https://policylayer.com/tools/flowdot-llc-mcp-server/browser-navigate.md - `browser_sequence` — Execute — https://policylayer.com/tools/flowdot-llc-mcp-server/browser-sequence.md - `browser_wait_for` — Execute — https://policylayer.com/tools/flowdot-llc-mcp-server/browser-wait-for.md - …and 176 more: https://policylayer.com/tools/flowdot-llc-mcp-server.md ## For agents This record is a snapshot.
