Parameters from the server's own tool schema.
This tool modifies existing data (a custom item) reversibly without permanently deleting it or executing arbitrary operations. It falls squarely in the Write category. Severity is medium because unauthorized updates to user-defined items in a training/fitness app could corrupt workflow data, but the damage is recoverable through revision or restoration.

Register the Intervals Icu Api MCP server in PolicyLayer and add a rule for updateCustomItem: 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 Intervals Icu Api. Nothing to install.
updateCustomItem 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 updateCustomItem 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 updateCustomItem. 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.
updateCustomItem is provided by the Intervals Icu Api MCP server (intervals-icu-api-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
