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

These attack patterns abuse exactly the kind of access refine_interface 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 to refine a previously generated Gravity AI UI composed payload with a natural-language instruction. This does not save or publish the result.. It is categorised as a Write tool in the Gravity AI UI MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Gravity AI UI MCP server in PolicyLayer and add a rule for refine_interface: 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 Gravity AI UI. Nothing to install.
refine_interface 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 refine_interface 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 refine_interface. 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.
refine_interface is provided by the Gravity AI UI MCP server (https://gravity-ai.ydb-qdrant.tech/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
