# update_app_file Update the content of an existing file in a FlowDot app. Updates the file Agent View of the PolicyLayer registry record for `update_app_file`. HTML page: https://policylayer.com/tools/flowdot-llc-mcp-server/update-app-file ## Facts - Tool: `update_app_file` - 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: Write (Medium 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": "update_app_file", "arguments": {} } } ``` ## Why update_app_file is rated Medium This tool modifies existing file content within a FlowDot app. It is a Write operation because it creates or modifies data reversibly (the update can typically be undone or reverted, and it does not permanently delete or destroy data). From the tool's own definition: "Tool description states 'Update the content of an existing file in a FlowDot app' and 'Updates the file' — the verb 'update' indicates reversible modification of data." ## Use case AI agents use update_app_file to create or update resources in FlowDot MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your FlowDot MCP Server environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches FlowDot MCP Server: ```json { "version": "1", "default": "deny", "tools": { "update_app_file": { "limits": [ { "counter": "update_app_file_rate", "window": "minute", "max": 30, "scope": "grant" } ] } } } ``` ## 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.
