AI agents use toggle_flag_environment 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 toggle_flag_environment 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.

Enable or disable a feature flag in a specific environment using the Unleash Admin API. For gradual rollouts, configure a flexibleRollout strategy first via set_flag_rollout.. 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 toggle_flag_environment: 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.
toggle_flag_environment 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 toggle_flag_environment 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 toggle_flag_environment. 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.
toggle_flag_environment 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.
