AI agents call time__get_current_time to retrieve information from Mcpd Proxy without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries time information without modifying, executing external code, deleting data, or affecting financial systems. It is a simple read operation with minimal risk—time data is universally available and cannot be misused to cause harm regardless of agent argument manipulation.
From the tool's definition Tool name is 'get_current_time' and description indicates it retrieves the current time from a 'time' server. The verb 'get' and the nature of time data (read-only, no side effects) indicate a retrieval operation.
Documented attack patterns abuse exactly the kind of access time__get_current_time gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Mcpd Proxy, and nothing reaches the server without passing your rules. This is the rule we recommend for time__get_current_time:
{
"version": "1",
"default": "deny",
"tools": {
"time__get_current_time": {}
}
}time__get_current_time is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

get_current_time tool from time server. It is categorised as a Read tool in the Mcpd Proxy MCP Server, which means it retrieves data without modifying state.
Register the Mcpd Proxy MCP server in PolicyLayer and add a rule for time__get_current_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 Mcpd Proxy. Nothing to install.
time__get_current_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 time__get_current_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 time__get_current_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.
time__get_current_time is provided by the Mcpd Proxy MCP server (mozilla-ai/mcpd-proxy). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Mcpd Proxy, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
