AI agents use connect_app to create or modify resources in Flutter Skill. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call connect_app repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Flutter Skill.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

These attack patterns abuse exactly the kind of access connect_app gives an agent. Each links to the full case and the policy that stops it:
Other write tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.

[USE WHEN] • You have a specific VM Service URI (ws://...) • Reconnecting to a known app instance [ALTERNATIVES] • If you don't have URI: use scan_and_connect() to auto-find • If app not running: use launch_app() to start it [AUTO-FIX] If project_path is provided, automatically checks and fixes missing configuration: • Adds flutter_skill dependency to pubspec.yaml if missing • Adds FlutterSkillBinding initialization to main.dart if missing [MULTI-SESSION] Returns a session_id that can be used to target this specific app in subsequent tool calls. Omitting session_id in other tools will use the active session.. It is categorised as a Write tool in the Flutter Skill MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Flutter Skill MCP server in PolicyLayer and add a rule for connect_app: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Flutter Skill. Nothing to install.
connect_app is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the connect_app rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for connect_app. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
connect_app is provided by the Flutter Skill MCP server (flutter-skill). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
