Parameters from the server's own tool schema.
This tool creates new data (a custom item) within the Intervals.icu system, making it reversible via deletion or modification. It does not delete, execute code, or move money, so it falls under Write. Severity is medium because creating items could be misused to clutter the system or create misleading records, but the impact is bounded and reversible.
From the tool's definition Tool name is 'createCustomItem' and description states 'Create a custom item'. The verb 'create' and the action of making a new custom item indicate data modification.

Register the Intervals Icu Api MCP server in PolicyLayer and add a rule for createCustomItem: 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.
createCustomItem 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 createCustomItem 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 createCustomItem. 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.
createCustomItem 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.
