AI agents use create_flag to create or modify resources in Unleash. 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 create_flag 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 Unleash.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

These attack patterns abuse exactly the kind of access create_flag 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.
Create a new feature flag in Unleash. This tool creates a feature flag with the specified configuration. Choose the appropriate flag type: - release: For gradual feature rollouts to users - experiment: For A/B tests and experiments - operational: For system behavior and operational toggles - kill-switch: For emergency shutdowns or circuit breakers - permission: For role-based access control Best practices: 1. Use clear, descriptive names (e.g.,. It is categorised as a Write tool in the Unleash MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Unleash MCP server in PolicyLayer and add a rule for create_flag: 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 Unleash. Nothing to install.
create_flag 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 create_flag 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 create_flag. 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.
create_flag is provided by the Unleash MCP server (Unleash/unleash-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
