AI agents call currentDateTime to retrieve information from Mailmodo without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns the current date and time for a specified timezone. It performs no modifications, deletions, or external operations—purely a data retrieval function. The minimal blast radius (wrong timestamp used in logic) and read-only nature place it firmly in the Read category with low severity.
From the tool's definition Tool name 'currentDateTime' and description 'Get Current Date and time for timezone' indicate a retrieval operation with no side effects.
Attacks that exploit this kind of access
Get Current Date and time for timezone. if timezone is not passed default to UTC. It is categorised as a Read tool in the Mailmodo MCP Server, which means it retrieves data without modifying state.
Register the Mailmodo MCP server in PolicyLayer and add a rule for currentDateTime: 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 Mailmodo. Nothing to install.
currentDateTime is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the currentDateTime 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 currentDateTime. 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.
currentDateTime is provided by the Mailmodo MCP server (mailmodo/mailmodo-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
