Parameters from the server's own tool schema.
The tool performs an irreversible deletion operation on message data. Once deleted, the message cannot be recovered through normal means. This falls squarely into the Destructive category as it permanently removes data. Severity is high because deletion of user messages could result in loss of important communications or records, and an agent misusing this tool could delete many messages with harmful intent.
From the tool's definition Tool name is 'deleteMessage' with description 'Delete a message' — uses the verb 'Delete' which indicates irreversible removal of data.

Register the Intervals Icu Api MCP server in PolicyLayer and add a rule for deleteMessage: 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.
deleteMessage is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the deleteMessage 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 deleteMessage. 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.
deleteMessage 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.
