AI agents call convert_time to retrieve information from Mcp Time without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
time | string | Yes | The time to convert (e.g., "2025-03-23 12:30:00") |
sourceTimezone | string | Yes | Source IANA timezone name (e.g., "Asia/Shanghai") |
targetTimezone | string | Yes | Target IANA timezone name (e.g., "Europe/London") |
Parameters from the server's own tool schema.
This tool performs a stateless timezone conversion calculation. It reads input time and timezone parameters, computes the equivalent time in the target timezone, and returns the result. No data is written, deleted, or executed; no external systems are affected.
From the tool's definition 'Converts a time from a source IANA timezone to a target IANA timezone' — pure computation/transformation with no side effects
Attacks that exploit this kind of access
Converts a time from a source IANA timezone to a target IANA timezone. It is categorised as a Read tool in the Mcp Time MCP Server, which means it retrieves data without modifying state.
convert_time accepts 3 parameters: time, sourceTimezone, targetTimezone. Required: time, sourceTimezone, targetTimezone. The full parameter table on this page comes from the server's own tool schema.
Register the Mcp Time MCP server in PolicyLayer and add a rule for convert_time: 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 Mcp Time. Nothing to install.
convert_time 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 convert_time 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 convert_time. 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.
convert_time is provided by the Mcp Time MCP server (@mcpcentral/mcp-time). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
