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

These attack patterns abuse exactly the kind of access apply_ugc gives an agent. Each links to the full case and the policy that stops it:

User-generated content — looks like a real person captured it casually. Choose: phone shot, film point-and-shoot, mirror selfie, or car selfie.. It is categorised as a Write tool in the Switch MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Switch MCP server in PolicyLayer and add a rule for apply_ugc: 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 Switch. Nothing to install.
apply_ugc 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 apply_ugc 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 apply_ugc. 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.
apply_ugc is provided by the Switch MCP server (https://mcp.switchapp.ai/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
