Use to update account settings including agent preferences and email notifications. Only include fields you want to change. Write operation — requires Pro tier or higher.
AI agents use update_settings to create or update resources in Rentalot MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Rentalot MCP Server environment.
This tool creates or modifies data reversibly (account settings, preferences, notifications) as confirmed by the explicit 'Write operation' designation. It does not delete data (not Destructive), execute code (not Execute), move money (not Financial), or retrieve data (not Read). The medium severity reflects that misuse could alter account configuration but is generally reversible.
From the tool's definition Tool description explicitly states 'Write operation' and describes updating 'account settings including agent preferences and email notifications.' These are configuration changes that modify data reversibly without deleting or executing code.
Attacks that exploit this kind of access
Use to update account settings including agent preferences and email notifications. Only include fields you want to change. Write operation — requires Pro tier or higher. It is categorised as a Write tool in the Rentalot MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Rentalot MCP Server MCP server in PolicyLayer and add a rule for update_settings: 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 Rentalot MCP Server. Nothing to install.
update_settings 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 update_settings 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 update_settings. 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.
update_settings is provided by the Rentalot MCP Server MCP server (rentalot-ai/rentalot-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
